+Email clients info for Linux
+======================================================================
+
+General Preferences
+----------------------------------------------------------------------
+Patches for the Linux kernel are submitted via email, preferably as
+inline text in the body of the email.  Some maintainers accept
+attachments, but then the attachments should have content-type
+"text/plain".  However, attachments are generally frowned upon because
+it makes quoting portions of the patch more difficult in the patch
+review process.
+
+Email clients that are used for Linux kernel patches should send the
+patch text untouched.  For example, they should not modify or delete tabs
+or spaces, even at the beginning or end of lines.
+
+Don't send patches with "format=flowed".  This can cause unexpected
+and unwanted line breaks.
+
+Don't let your email client do automatic word wrapping for you.
+This can also corrupt your patch.
+
+Email clients should not modify the character set encoding of the text.
+Emailed patches should be in ASCII or UTF-8 encoding only.
+If you configure your email client to send emails with UTF-8 encoding,
+you avoid some possible charset problems.
+
+Email clients should generate and maintain References: or In-Reply-To:
+headers so that mail threading is not broken.
+
+Copy-and-paste (or cut-and-paste) usually does not work for patches
+because tabs are converted to spaces.  Using xclipboard, xclip, and/or
+xcutsel may work, but it's best to test this for yourself or just avoid
+copy-and-paste.
+
+Don't use PGP/GPG signatures in mail that contains patches.
+This breaks many scripts that read and apply the patches.
+(This should be fixable.)
+
+It's a good idea to send a patch to yourself, save the received message,
+and successfully apply it with 'patch' before sending patches to Linux
+mailing lists.
+
+
+Some email client (MUA) hints
+----------------------------------------------------------------------
+Here are some specific MUA configuration hints for editing and sending
+patches for the Linux kernel.  These are not meant to be complete
+software package configuration summaries.
+
+Legend:
+TUI = text-based user interface
+GUI = graphical user interface
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Alpine (TUI)
+
+Config options:
+In the "Sending Preferences" section:
+
+- "Do Not Send Flowed Text" must be enabled
+- "Strip Whitespace Before Sending" must be disabled
+
+When composing the message, the cursor should be placed where the patch
+should appear, and then pressing CTRL-R let you specify the patch file
+to insert into the message.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Evolution (GUI)
+
+Some people use this successfully for patches.
+
+When composing mail select: Preformat
+  from Format->Heading->Preformatted (Ctrl-7)
+  or the toolbar
+
+Then use:
+  Insert->Text File... (Alt-n x)
+to insert the patch.
+
+You can also "diff -Nru old.c new.c | xclip", select Preformat, then
+paste with the middle button.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Kmail (GUI)
+
+Some people use Kmail successfully for patches.
+
+The default setting of not composing in HTML is appropriate; do not
+enable it.
+
+When composing an email, under options, uncheck "word wrap". The only
+disadvantage is any text you type in the email will not be word-wrapped
+so you will have to manually word wrap text before the patch. The easiest
+way around this is to compose your email with word wrap enabled, then save
+it as a draft. Once you pull it up again from your drafts it is now hard
+word-wrapped and you can uncheck "word wrap" without losing the existing
+wrapping.
+
+At the bottom of your email, put the commonly-used patch delimiter before
+inserting your patch:  three hyphens (---).
+
+Then from the "Message" menu item, select insert file and choose your patch.
+As an added bonus you can customise the message creation toolbar menu
+and put the "insert file" icon there.
+
+You can safely GPG sign attachments, but inlined text is preferred for
+patches so do not GPG sign them.  Signing patches that have been inserted
+as inlined text will make them tricky to extract from their 7-bit encoding.
+
+If you absolutely must send patches as attachments instead of inlining
+them as text, right click on the attachment and select properties, and
+highlight "Suggest automatic display" to make the attachment inlined to
+make it more viewable.
+
+When saving patches that are sent as inlined text, select the email that
+contains the patch from the message list pane, right click and select
+"save as".  You can use the whole email unmodified as a patch if it was
+properly composed.  There is no option currently to save the email when you
+are actually viewing it in its own window -- there has been a request filed
+at kmail's bugzilla and hopefully this will be addressed.  Emails are saved
+as read-write for user only so you will have to chmod them to make them
+group and world readable if you copy them elsewhere.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Lotus Notes (GUI)
+
+Run away from it.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Mutt (TUI)
+
+Plenty of Linux developers use mutt, so it must work pretty well.
+
+Mutt doesn't come with an editor, so whatever editor you use should be
+used in a way that there are no automatic linebreaks.  Most editors have
+an "insert file" option that inserts the contents of a file unaltered.
+
+To use 'vim' with mutt:
+  set editor="vi"
+
+  If using xclip, type the command
+  :set paste
+  before middle button or shift-insert or use
+  :r filename
+
+if you want to include the patch inline.
+(a)ttach works fine without "set paste".
+
+Config options:
+It should work with default settings.
+However, it's a good idea to set the "send_charset" to:
+  set send_charset="us-ascii:utf-8"
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Pine (TUI)
+
+Pine has had some whitespace truncation issues in the past, but these
+should all be fixed now.
+
+Use alpine (pine's successor) if you can.
+
+Config options:
+- quell-flowed-text is needed for recent versions
+- the "no-strip-whitespace-before-send" option is needed
+
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Sylpheed (GUI)
+
+- Works well for inlining text (or using attachments).
+- Allows use of an external editor.
+- Not good for IMAP.
+- Is slow on large folders.
+- Won't do TLS SMTP auth over a non-SSL connection.
+- Has a helpful ruler bar in the compose window.
+- Adding addresses to address book doesn't understand the display name
+  properly.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Thunderbird (GUI)
+
+By default, thunderbird likes to mangle text, but there are ways to
+coerce it into being nice.
+
+- Under account settings, composition and addressing, uncheck "Compose
+  messages in HTML format".
+
+- Edit your Thunderbird config settings to tell it not to wrap lines:
+      user_pref("mailnews.wraplength", 0);
+
+- Edit your Thunderbird config settings so that it won't use format=flowed:
+      user_pref("mailnews.send_plaintext_flowed", false);
+
+- You need to get Thunderbird into preformat mode:
+. If you compose HTML messages by default, it's not too hard. Just select
+  "Preformat" from the drop-down box just under the subject line.
+. If you compose in text by default, you have to tell it to compose a new
+  message in HTML (just as a one-off), and then force it from there back to
+  text, else it will wrap lines. To do this, use shift-click on the Write
+  icon to compose to get HTML compose mode, then select "Preformat" from
+  the drop-down box just under the subject line.
+
+- Allows use of an external editor:
+  The easiest thing to do with Thunderbird and patches is to use an
+  "external editor" extension and then just use your favorite $EDITOR
+  for reading/merging patches into the body text.  To do this, download
+  and install the extension, then add a button for it using
+  View->Toolbars->Customize... and finally just click on it when in the
+  Compose dialog.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+TkRat (GUI)
+
+Works.  Use "Insert file..." or external editor.
+
+                                ###

+with the VBE 2.0 standard.
+
+Unlike other drivers, uvesafb makes use of a userspace helper called
+v86d.  v86d is used to run the x86 Video BIOS code in a simulated and
+controlled environment.  This allows uvesafb to function on arches other
+than x86.  Check the v86d documentation for a list of currently supported
+arches.
+
+v86d source code can be downloaded from the following website:
+  http://dev.gentoo.org/~spock/projects/uvesafb
+
+Please refer to the v86d documentation for detailed configuration and
+installation instructions.
+
+Note that the v86d userspace helper has to be available at all times in
+order for uvesafb to work properly.  If you want to use uvesafb during
+early boot, you will have to include v86d into an initramfs image, and
+either compile it into the kernel or use it as an initrd.
+
+2. Caveats and limitations
+--------------------------
+
+uvesafb is a _generic_ driver which supports a wide variety of video
+cards, but which is ultimately limited by the Video BIOS interface.
+The most important limitations are:
+
+- Lack of any type of acceleration.
+- A strict and limited set of supported video modes.  Often the native
+  or most optimal resolution/refresh rate for your setup will not work
+  with uvesafb, simply because the Video BIOS doesn't support the
+  video mode you want to use.  This can be especially painful with
+  widescreen panels, where native video modes don't have the 4:3 aspect
+  ratio, which is what most BIOS-es are limited to.
+- Adjusting the refresh rate is only possible with a VBE 3.0 compliant
+  Video BIOS.  Note that many nVidia Video BIOS-es claim to be VBE 3.0
+  compliant, while they simply ignore any refresh rate settings.
+
+3. Configuration
+----------------
+
+uvesafb can be compiled either as a module, or directly into the kernel.
+In both cases it supports the same set of configuration options, which
+are either given on the kernel command line or as module parameters, e.g.:
+
+ video=uvesafb:1024x768-32,mtrr:3,ywrap (compiled into the kernel)
+
+ # modprobe uvesafb mode=1024x768-32 mtrr=3 scroll=ywrap  (module)
+
+Accepted options:
+
+ypan    Enable display panning using the VESA protected mode
+        interface.  The visible screen is just a window of the
+        video memory, console scrolling is done by changing the
+        start of the window.  Available on x86 only.
+
+ywrap   Same as ypan, but assumes your gfx board can wrap-around
+        the video memory (i.e. starts reading from top if it
+        reaches the end of video memory).  Faster than ypan.
+        Available on x86 only.
+
+redraw  Scroll by redrawing the affected part of the screen, this
+        is the safe (and slow) default.
+
+(If you're using uvesafb as a module, the above three options are
+ used a parameter of the scroll option, e.g. scroll=ypan.)
+
+vgapal  Use the standard VGA registers for palette changes.
+
+pmipal  Use the protected mode interface for palette changes.
+        This is the default if the protected mode interface is
+        available.  Available on x86 only.
+
+mtrr:n  Setup memory type range registers for the framebuffer
+        where n:
+              0 - disabled (equivalent to nomtrr) (default)
+              1 - uncachable
+              2 - write-back
+              3 - write-combining
+              4 - write-through
+
+        If you see the following in dmesg, choose the type that matches
+        the old one.  In this example, use "mtrr:2".
+...
+mtrr: type mismatch for e0000000,8000000 old: write-back new: write-combining
+...
+
+nomtrr  Do not use memory type range registers.
+
+vremap:n
+        Remap 'n' MiB of video RAM.  If 0 or not specified, remap memory
+        according to video mode.
+
+vtotal:n
+        If the video BIOS of your card incorrectly determines the total
+        amount of video RAM, use this option to override the BIOS (in MiB).
+
+<mode>  The mode you want to set, in the standard modedb format.  Refer to
+        modedb.txt for a detailed description.  When uvesafb is compiled as
+        a module, the mode string should be provided as a value of the
+        'mode' option.
+
+vbemode:x
+        Force the use of VBE mode x.  The mode will only be set if it's
+        found in the VBE-provided list of supported modes.
+        NOTE: The mode number 'x' should be specified in VESA mode number
+        notation, not the Linux kernel one (eg. 257 instead of 769).
+        HINT: If you use this option because normal <mode> parameter does
+        not work for you and you use a X server, you'll probably want to
+        set the 'nocrtc' option to ensure that the video mode is properly
+        restored after console <-> X switches.
+
+nocrtc  Do not use CRTC timings while setting the video mode.  This option
+        has any effect only if the Video BIOS is VBE 3.0 compliant.  Use it
+        if you have problems with modes set the standard way.  Note that
+        using this option implies that any refresh rate adjustments will
+        be ignored and the refresh rate will stay at your BIOS default (60 Hz).
+
+noedid  Do not try to fetch and use EDID-provided modes.
+
+noblank Disable hardware blanking.
+
+v86d:path
+        Set path to the v86d executable. This option is only available as
+        a module parameter, and not as a part of the video= string.  If you
+        need to use it and have uvesafb built into the kernel, use
+        uvesafb.v86d="path".
+
+Additionally, the following parameters may be provided.  They all override the
+EDID-provided values and BIOS defaults.  Refer to your monitor's specs to get
+the correct values for maxhf, maxvf and maxclk for your hardware.
+
+maxhf:n     Maximum horizontal frequency (in kHz).
+maxvf:n     Maximum vertical frequency (in Hz).
+maxclk:n    Maximum pixel clock (in MHz).
+
+4. The sysfs interface
+----------------------
+
+uvesafb provides several sysfs nodes for configurable parameters and
+additional information.
+
+Driver attributes:
+
+/sys/bus/platform/drivers/uvesafb
+  - v86d (default: /sbin/v86d)
+    Path to the v86d executable. v86d is started by uvesafb
+    if an instance of the daemon isn't already running.
+
+Device attributes:
+
+/sys/bus/platform/drivers/uvesafb/uvesafb.0
+  - nocrtc
+    Use the default refresh rate (60 Hz) if set to 1.
+
+  - oem_product_name
+  - oem_product_rev
+  - oem_string
+  - oem_vendor
+    Information about the card and its maker.
+
+  - vbe_modes
+    A list of video modes supported by the Video BIOS along with their
+    VBE mode numbers in hex.
+
+  - vbe_version
+    A BCD value indicating the implemented VBE standard.
+
+5. Miscellaneous
+----------------
+
+Uvesafb will set a video mode with the default refresh rate and timings
+from the Video BIOS if you set pixclock to 0 in fb_var_screeninfo.

+In 2.6.2* /proc/interrupts was expanded again.  This time the goal was for

+  THR -- interrupt raised when a machine check threshold counter

+  a configurable threshold.  Only available on some systems.
+
+  TRM -- a thermal event interrupt occurs when a temperature threshold
+  has been exceeded for the CPU.  This interrupt may also be generated
+  when the temperature drops back to normal.
+
+  SPU -- a spurious interrupt is some interrupt that was raised then lowered
+  by some IO device before it could be fully processed by the APIC.  Hence
+  the APIC sees the interrupt but does not know what device it came from.
+  For this case the APIC will generate the interrupt with a IRQ vector
+  of 0xff. This might also be generated by chipset bugs.

+suppressed when the system is a uniprocessor.  As of this writing, only
+i386 and x86_64 platforms support the new IRQ vector displays.
+
+Of some interest is the introduction of the /proc/irq directory to 2.4.
 It could be used to set IRQ to CPU affinity, this means that you can "hook" an
 IRQ to only one CPU, or to exclude a CPU of handling IRQs. The contents of the

+Quota subsystem
+===============
+
+Quota subsystem allows system administrator to set limits on used space and
+number of used inodes (inode is a filesystem structure which is associated
+with each file or directory) for users and/or groups. For both used space and
+number of used inodes there are actually two limits. The first one is called
+softlimit and the second one hardlimit.  An user can never exceed a hardlimit
+for any resource. User is allowed to exceed softlimit but only for limited
+period of time. This period is called "grace period" or "grace time". When
+grace time is over, user is not able to allocate more space/inodes until he
+frees enough of them to get below softlimit.
+
+Quota limits (and amount of grace time) are set independently for each
+filesystem.
+
+For more details about quota design, see the documentation in quota-tools package
+(http://sourceforge.net/projects/linuxquota).
+
+Quota netlink interface
+=======================
+When user exceeds a softlimit, runs out of grace time or reaches hardlimit,
+quota subsystem traditionally printed a message to the controlling terminal of
+the process which caused the excess. This method has the disadvantage that
+when user is using a graphical desktop he usually cannot see the message.
+Thus quota netlink interface has been designed to pass information about
+the above events to userspace. There they can be captured by an application
+and processed accordingly.
+
+The interface uses generic netlink framework (see
+http://lwn.net/Articles/208755/ and http://people.suug.ch/~tgr/libnl/ for more
+details about this layer). The name of the quota generic netlink interface
+is "VFS_DQUOT". Definitions of constants below are in <linux/quota.h>.
+  Currently, the interface supports only one message type QUOTA_NL_C_WARNING.
+This command is used to send a notification about any of the above mentioned
+events. Each message has six attributes. These are (type of the argument is
+in parentheses):
+        QUOTA_NL_A_QTYPE (u32)
+	  - type of quota being exceeded (one of USRQUOTA, GRPQUOTA)
+        QUOTA_NL_A_EXCESS_ID (u64)
+	  - UID/GID (depends on quota type) of user / group whose limit
+	    is being exceeded.
+        QUOTA_NL_A_CAUSED_ID (u64)
+	  - UID of a user who caused the event
+        QUOTA_NL_A_WARNING (u32)
+	  - what kind of limit is exceeded:
+		QUOTA_NL_IHARDWARN - inode hardlimit
+		QUOTA_NL_ISOFTLONGWARN - inode softlimit is exceeded longer
+		  than given grace period
+		QUOTA_NL_ISOFTWARN - inode softlimit
+		QUOTA_NL_BHARDWARN - space (block) hardlimit
+		QUOTA_NL_BSOFTLONGWARN - space (block) softlimit is exceeded
+		  longer than given grace period.
+		QUOTA_NL_BSOFTWARN - space (block) softlimit
+        QUOTA_NL_A_DEV_MAJOR (u32)
+	  - major number of a device with the affected filesystem

+Exporting kernel headers for use by userspace
+=============================================
+
+The "make headers_install" command exports the kernel's header files in a
+form suitable for use by userspace programs.
+
+The linux kernel's exported header files describe the API for user space
+programs attempting to use kernel services.  These kernel header files are
+used by the system's C library (such as glibc or uClibc) to define available
+system calls, as well as constants and structures to be used with these
+system calls.  The C library's header files include the kernel header files
+from the "linux" subdirectory.  The system's libc headers are usually
+installed at the default location /usr/include and the kernel headers in
+subdirectories under that (most notably /usr/include/linux and
+/usr/include/asm).
+
+Kernel headers are backwards compatible, but not forwards compatible.  This
+means that a program built against a C library using older kernel headers
+should run on a newer kernel (although it may not have access to new
+features), but a program built against newer kernel headers may not work on an
+older kernel.
+
+The "make headers_install" command can be run in the top level directory of the
+kernel source code (or using a standard out-of-tree build).  It takes two
+optional arguments:
+
+  make headers_install ARCH=i386 INSTALL_HDR_PATH=/usr/include
+
+ARCH indicates which architecture to produce headers for, and defaults to the
+current architecture.  The linux/asm directory of the exported kernel headers
+is platform-specific, to see a complete list of supported architectures use
+the command:
+
+  ls -d include/asm-* | sed 's/.*-//'
+
+INSTALL_HDR_PATH indicates where to install the headers.  It defaults to
+"./usr/include".
+
+The command "make headers_install_all" exports headers for all architectures
+simultaneously.  (This is mostly of interest to distribution maintainers,
+who create an architecture-independent tarball from the resulting include
+directory.)  Remember to provide the appropriate linux/asm directory via "mv"
+or "ln -s" before building a C library with headers exported this way.
+
+The kernel header export infrastructure is maintained by David Woodhouse
+<dwmw2@infradead.org>.

+	This magic number seems to give pretty optimal throughput

+	without coming up with a number so large that we hog the whole
+	CPU. 
+	Specifically, with this number, out of about 134,000 status

+
     This module supports multiple cards and ISA PnP.
 
+    Note: the firmware file "wavefront.os" was located in the earlier
+          version in /etc.  Now it's loaded via firmware loader, and
+	  must be in the proper firmware path, such as /lib/firmware.
+	  Copy (or symlink) the file appropriately if you get an error
+	  regarding firmware downloading after upgrading the kernel.

+Notes on Power-Saving Mode
+==========================
+
+AC97 and HD-audio drivers have the automatic power-saving mode.
+This feature is enabled via Kconfig CONFIG_SND_AC97_POWER_SAVE
+and CONFIG_SND_HDA_POWER_SAVE options, respectively.
+
+With the automatic power-saving, the driver turns off the codec power
+appropriately when no operation is required.  When no applications use
+the device and/or no analog loopback is set, the power disablement is
+done fully or partially.  It'll save a certain power consumption, thus
+good for laptops (even for desktops).
+
+The time-out for automatic power-off can be specified via power_save
+module option of snd-ac97-codec and snd-hda-intel modules.  Specify
+the time-out value in seconds.  0 means to disable the automatic
+power-saving.  The default value of timeout is given via
+CONFIG_SND_AC97_POWER_SAVE_DEFAULT and
+CONFIG_SND_HDA_POWER_SAVE_DEFAULT Kconfig options.  Setting this to 1
+(the minimum value) isn't recommended because many applications try to
+reopen the device frequently.  10 would be a good choice for normal
+operations.
+
+The power_save option is exported as writable.  This means you can
+adjust the value via sysfs on the fly.  For example, to turn on the
+automatic power-save mode with 10 seconds, write to
+/sys/modules/snd_ac97_codec/parameters/power_save (usually as root):
+
+	# echo 10 > /sys/modules/snd_ac97_codec/parameters/power_save
+
+
+Note that you might hear click noise/pop when changing the power
+state.  Also, it often takes certain time to wake up from the
+power-down to the active state.  These are often hardly to fix, so
+don't report extra bug reports unless you have a fix patch ;-)
+
+For HD-audio interface, there is another module option,
+power_save_controller.  This enables/disables the power-save mode of
+the controller side.  Setting this on may reduce a bit more power
+consumption, but might result in longer wake-up time and click noise.
+Try to turn it off when you experience such a thing too often.

@@ -302,31 +302,30 @@ MEMORY POLICIES AND CPUSETS
 
 Memory policies work within cpusets as described above.  For memory policies
 that require a node or set of nodes, the nodes are restricted to the set of
-nodes whose memories are allowed by the cpuset constraints.  If the
-intersection of the set of nodes specified for the policy and the set of nodes
-allowed by the cpuset is the empty set, the policy is considered invalid and
-cannot be installed.
+nodes whose memories are allowed by the cpuset constraints.  If the nodemask
+specified for the policy contains nodes that are not allowed by the cpuset, or
+the intersection of the set of nodes specified for the policy and the set of
+nodes with memory is the empty set, the policy is considered invalid
+and cannot be installed.
 
 The interaction of memory policies and cpusets can be problematic for a
 couple of reasons:
 
-1) the memory policy APIs take physical node id's as arguments.  However, the
-   memory policy APIs do not provide a way to determine what nodes are valid
-   in the context where the application is running.  An application MAY consult
-   the cpuset file system [directly or via an out of tree, and not generally
-   available, libcpuset API] to obtain this information, but then the
-   application must be aware that it is running in a cpuset and use what are
-   intended primarily as administrative APIs.
-
-   However, as long as the policy specifies at least one node that is valid
-   in the controlling cpuset, the policy can be used.
+1) the memory policy APIs take physical node id's as arguments.  As mentioned
+   above, it is illegal to specify nodes that are not allowed in the cpuset.
+   The application must query the allowed nodes using the get_mempolicy()
+   API with the MPOL_F_MEMS_ALLOWED flag to determine the allowed nodes and
+   restrict itself to those nodes.  However, the resources available to a
+   cpuset can be changed by the system administrator, or a workload manager
+   application, at any time.  So, a task may still get errors attempting to
+   specify policy nodes, and must query the allowed memories again.
 
 2) when tasks in two cpusets share access to a memory region, such as shared
    memory segments created by shmget() of mmap() with the MAP_ANONYMOUS and
    MAP_SHARED flags, and any of the tasks install shared policy on the region,
    only nodes whose memories are allowed in both cpusets may be used in the
-   policies.  Again, obtaining this information requires "stepping outside"
-   the memory policy APIs, as well as knowing in what cpusets other task might
-   be attaching to the shared region, to use the cpuset information.
+   policies.  Obtaining this information requires "stepping outside" the
+   memory policy APIs to use the cpuset information and requires that one
+   know in what cpusets other task might be attaching to the shared region.
    Furthermore, if the cpusets' allowed memory sets are disjoint, "local"
    allocation is the only valid policy.

+	This User-Mode Linux network transport allows one or more running

+	with the rest of the world using Virtual Distributed Ethernet,
+	an improved fork of uml_switch.
+
+	You must have libvdeplug installed in order to build the vde

+
+	To use this form of networking, you will need to run vde_switch
+	on the host.
+
+	For more information, see <http://wiki.virtualsquare.org/>

+ *
+ * Transfers must be in one transaction or the firmware goes bonkers.
+ * This means that the transfer must either be small enough to do a
+ * byte based transfer or it must be padded to a multiple of the
+ * current block size.
+ *
+ * As SDIO is still new to the kernel, it is unfortunately common with
+ * bugs in the host controllers related to that. One such bug is that 
+ * controllers cannot do transfers that aren't a multiple of 4 bytes.
+ * If you don't have time to fix the host controller driver, you can
+ * work around the problem by modifying if_sdio_host_to_card() and

- * Keyboard mappings for DEC LK201/401/501 keyboards
- *
- * 17.05.99 Michael Engel (engel@unix-ag.org)
- *
- * DEC US keyboards generate keycodes in the range 0x55 - 0xfb
- *
- * This conflicts with Linux scancode conventions which define
- * 0x00-0x7f as "normal" and 0x80-0xff as "shifted" scancodes, so we
- * have to remap the keycodes to 0x00-0x7f with the scancodeRemap
- * array. The generated scancode is simply the number of the key counted
- * from the left upper to the right lower corner of the keyboard ...
- *
- * These scancodes are then being remapped (I hope ;-)) with the
- * lk501*map[] arrays which define scancode -> Linux code mapping
- *
- * Oh man is this horrible ;-)
- *
- * Scancodes with dual labels exist for keyboards as follows:
- *
- * code:  left label          / right label
- *
- * 0x73:  LKx01, LK421        / LK443, LK444
- * 0x74:  LKx01, LK421        / LK443, LK444
- * 0x7c:  LKx01, LK421        / LK443, LK444
- * 0x8a:  LKx01, LK421        / LK443, LK444
- * 0x8b:  LKx01, LK421        / LK443, LK444
- * 0x8c:  LKx01, LK421        / LK443, LK444
- * 0x8d:  LKx01, LK421        / LK443, LK444
- * 0x8e:  LKx01, LK421        / LK443, LK444
- * 0x8f:  LKx01, LK421        / LK443, LK444
- * 0x9c:  LKx01, LK421        / LK443, LK444
- * 0xa1:  LKx01, LK421        / LK443, LK444

-/*
- * Header file used to associate behaviors with virtualized objects.
- *
- * A virtualized object is an internal, virtualized representation of
- * OS entities such as persistent files, processes, or sockets.  Examples
- * of virtualized objects include vnodes, vprocs, and vsockets.  Often
- * a virtualized object is referred to simply as an "object."
- *
- * A behavior is essentially an implementation layer associated with
- * an object.  Multiple behaviors for an object are chained together,
- * the order of chaining determining the order of invocation.  Each
- * behavior of a given object implements the same set of interfaces
- * (e.g., the VOP interfaces).
- *
- * Behaviors may be dynamically inserted into an object's behavior chain,
- * such that the addition is transparent to consumers that already have
- * references to the object.  Typically, a given behavior will be inserted
- * at a particular location in the behavior chain.  Insertion of new
- * behaviors is synchronized with operations-in-progress (oip's) so that
- * the oip's always see a consistent view of the chain.
- *
- * The term "interposition" is used to refer to the act of inserting
- * a behavior such that it interposes on (i.e., is inserted in front
- * of) a particular other behavior.  A key example of this is when a
- * system implementing distributed single system image wishes to
- * interpose a distribution layer (providing distributed coherency)
- * in front of an object that is otherwise only accessed locally.
- *
- * Note that the traditional vnode/inode combination is simply a virtualized
- * object that has exactly one associated behavior.
- *
- * Behavior synchronization is logic which is necessary under certain
- * circumstances that there is no conflict between ongoing operations
- * traversing the behavior chain and those dynamically modifying the
- * behavior chain.  Because behavior synchronization adds extra overhead
- * to virtual operation invocation, we want to restrict, as much as
- * we can, the requirement for this extra code, to those situations
- * in which it is truly necessary.
- *
- * Behavior synchronization is needed whenever there's at least one class
- * of object in the system for which:
- * 1) multiple behaviors for a given object are supported,
- * -- AND --
- * 2a) insertion of a new behavior can happen dynamically at any time during
- *     the life of an active object,
- *	-- AND --
- *	3a) insertion of a new behavior needs to synchronize with existing
- *	    ops-in-progress.
- *	-- OR --
- *	3b) multiple different behaviors can be dynamically inserted at
- *	    any time during the life of an active object
- *	-- OR --
- *	3c) removal of a behavior can occur at any time during the life of
- *	    an active object.
- * -- OR --
- * 2b) removal of a behavior can occur at any time during the life of an
- *     active object

+ * Inode state bits.  Protected by inode_lock.
+ *
+ * Three bits determine the dirty state of the inode, I_DIRTY_SYNC,
+ * I_DIRTY_DATASYNC and I_DIRTY_PAGES.
+ *
+ * Four bits define the lifetime of an inode.  Initially, inodes are I_NEW,
+ * until that flag is cleared.  I_WILL_FREE, I_FREEING and I_CLEAR are set at
+ * various stages of removing an inode.
+ *
+ * Two bits are used for locking and completion notification, I_LOCK and I_SYNC.
+ *
+ * I_DIRTY_SYNC		Inode itself is dirty.
+ * I_DIRTY_DATASYNC	Data-related inode changes pending
+ * I_DIRTY_PAGES	Inode has dirty pages.  Inode itself may be clean.
+ * I_NEW		get_new_inode() sets i_state to I_LOCK|I_NEW.  Both
+ *			are cleared by unlock_new_inode(), called from iget().
+ * I_WILL_FREE		Must be set when calling write_inode_now() if i_count
+ *			is zero.  I_FREEING must be set when I_WILL_FREE is
+ *			cleared.
+ * I_FREEING		Set when inode is about to be freed but still has dirty
+ *			pages or buffers attached or the inode itself is still
+ *			dirty.
+ * I_CLEAR		Set by clear_inode().  In this state the inode is clean
+ *			and can be destroyed.
+ *
+ *			Inodes that are I_WILL_FREE, I_FREEING or I_CLEAR are
+ *			prohibited for many purposes.  iget() must wait for
+ *			the inode to be completely released, then create it
+ *			anew.  Other functions will just ignore such inodes,
+ *			if appropriate.  I_LOCK is used for waiting.
+ *
+ * I_LOCK		Serves as both a mutex and completion notification.
+ *			New inodes set I_LOCK.  If two processes both create
+ *			the same inode, one of them will release its inode and
+ *			wait for I_LOCK to be released before returning.
+ *			Inodes in I_WILL_FREE, I_FREEING or I_CLEAR state can
+ *			also cause waiting on I_LOCK, without I_LOCK actually
+ *			being set.  find_inode() uses this to prevent returning
+ *			nearly-dead inodes.
+ * I_SYNC		Similar to I_LOCK, but limited in scope to writeback
+ *			of inode dirty data.  Having a seperate lock for this
+ *			purpose reduces latency and prevents some filesystem-
+ *			specific deadlocks.
+ *
+ * Q: Why does I_DIRTY_DATASYNC exist?  It appears as if it could be replaced
+ *    by (I_DIRTY_SYNC|I_DIRTY_PAGES).
+ * Q: What is the difference between I_WILL_FREE and I_FREEING?
+ * Q: igrab() only checks on (I_FREEING|I_WILL_FREE).  Should it also check on
+ *    I_CLEAR?  If not, why?

+	  by inserting a short delay after each one.  The delay is
+	  specified in milliseconds on the kernel command line,

+
+	  It is likely that you would also need to use "lpj=M" to preset
+	  the "loops per jiffie" value.
+	  See a previous boot log for the "lpj" value to use for your
+	  system, and then set "lpj=M" before setting "boot_delay=N".
+	  NOTE:  Using this option may adversely affect SMP systems.
+	  I.e., processors other than the first one may not boot up.

+ * The floating proportion is a time derivative with an exponentially decaying
+ * history:
+ *
+ *   p_{j} = \Sum_{i=0} (dx_{j}/dt_{-i}) / 2^(1+i)
+ *
+ * Where j is an element from {prop_local}, x_{j} is j's number of events,
+ * and i the time period over which the differential is taken. So d/dt_{-i} is
+ * the differential over the i-th last period.
+ *
+ * The decaying history gives smooth transitions. The time differential carries
+ * the notion of speed.
+ *
+ * The denominator is 2^(1+i) because we want the series to be normalised, ie.
+ *
+ *   \Sum_{i=0} 1/2^(1+i) = 1
+ *
+ * Further more, if we measure time (t) in the same events as x; so that:
+ *
+ *   t = \Sum_{j} x_{j}
+ *
+ * we get that:
+ *
+ *   \Sum_{j} p_{j} = 1
+ *
+ * Writing this in an iterative fashion we get (dropping the 'd's):
+ *
+ *   if (++x_{j}, ++t > period)
+ *     t /= 2;
+ *     for_each (j)
+ *       x_{j} /= 2;
+ *
+ * so that:
+ *
+ *   p_{j} = x_{j} / t;
+ *
+ * We optimize away the '/= 2' for the global time delta by noting that:
+ *
+ *   if (++t > period) t /= 2:
+ *
+ * Can be approximated by:
+ *
+ *   period/2 + (++t % period/2)
+ *
+ * [ Furthermore, when we choose period to be 2^n it can be written in terms of
+ *   binary operations and wraparound artefacts disappear. ]
+ *
+ * Also note that this yields a natural counter of the elapsed periods:
+ *
+ *   c = t / (period/2)
+ *
+ * [ Its monotonic increasing property can be applied to mitigate the wrap-
+ *   around issue. ]
+ *
+ * This allows us to do away with the loop over all prop_locals on each period
+ * expiration. By remembering the period count under which it was last accessed
+ * as c_{j}, we can obtain the number of 'missed' cycles from:
+ *
+ *   c - c_{j}
+ *
+ * We can then lazily catch up to the global period count every time we are
+ * going to use x_{j}, by doing:
+ *
+ *   x_{j} /= 2^(c - c_{j}), c_{j} = c

+ * Virtual memory maps allow VM primitives pfn_to_page, page_to_pfn,
+ * virt_to_page, page_address() to be implemented as a base offset
+ * calculation without memory access.
+ *
+ * However, virtual mappings need a page table and TLBs. Many Linux
+ * architectures already map their physical space using 1-1 mappings
+ * via TLBs. For those arches the virtual memmory map is essentially
+ * for free if we use the same page size as the 1-1 mappings. In that
+ * case the overhead consists of a few additional pages that are
+ * allocated to create a view of memory for vmemmap.
+ *
+ * The architecture is expected to provide a vmemmap_populate() function
+ * to instantiate the mapping.

+ *    there is no mechanism yet for this driver and the machine driver to
+ *    communicate the values of the M0, M1, MCLK1, and MCLK2 pins.
+ * 2) Only I2C is supported, not SPI
+ * 3) Only Master mode is supported, not Slave.
+ * 4) The machine driver's 'startup' function must call
+ *    cs4270_set_dai_sysclk() with the value of MCLK.
+ * 5) Only I2S and left-justified modes are supported
+ * 6) Power management is not supported
+ * 7) The only supported control is volume and hardware mute (if enabled)
