Many RTC routines were not protected against each other, so there are
potential races, for example, ntp-update against /dev/rtc. This patch
fixes them using rtc_lock.

The mips_rtc_lock is no longer needed because RTC operations should be
protected already by other mechanism. (rtc_lock, local_irq_save, etc.)
Also, locking whole rtc_get_time/rtc_set_time should be avoided while
some RTC routines might take very long time (a few seconds).

Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel
base page size to 64K. The resulting kernel still boots on any
hardware. On current machines with 4K pages support only, the kernel
will maintain 16 "subpages" for each 64K page transparently.
Note that while real 64K capable HW has been tested, the current patch
will not enable it yet as such hardware is not released yet, and I'm
still verifying with the firmware architects the proper to get the
information from the newer hypervisors.

We don't want to call dump_cpu_info() from cpu_init() after boot since
it produces a lot of unnecessary noise - since cpu_init() gets called

Patch from Richard Purdie
Update the PXA pm.c file to allow machines (such as the Sharp
Zaurus) to override the standard pm functions but reuse/wrap them
where needed.
The init call is made slightly earlier to give machine code an init
level to override them in removing any race.

Patch from Alessandro Zummo
This patch fixes AHB/PCI endianness problems when the
processor is in little-endian mode.
The patch configures the CSR register closely following the directives
in [1], paragraph 4.1, page 19.
According to the considerations in [1], page 11, while the AHB bus
supports both endian modes, on the IXP4XX it always uses big-endian.
The PCI bus is connected to the South AHB. A wrong setting in the CSR
register will thus cause a malfunctional PCI bus.
A schematic diagram of the bus interconnections on the IXP4XX
can be found in [1], page 18.
The patch has been verified to work on the NSLU2 in
both LE and BE modes.
The author is Peter Korsgaard.

Include autoconf.h into every kernel compilation via the gcc command line
using -imacros. This ensures that we have the kernel configuration
included from the start, rather than relying on each file having #include
<linux/config.h> as appropriate. History has shown that this is something
which is difficult to get right.
Since we now include the kernel configuration automatically, make
configcheck becomes meaningless, so remove it.

my patch "x86: initialise tss->io_bitmap_owner to something" (commit ID
d5cd4aadd3d220afac8e3e6d922e333592551f7d) introduced a problem with a
program (DOSEMU) that called ioperm after already doing some port i/o.
The problem is that a process switch return causes tss->io_bitmap_base
to be set to IO_BITMAP_OFFSET so that the fault (that *really* sets the
io bitmap) never triggers.
This fixes that regression.

Some visually impaired people use hardware devices which directly read
the vga screen. When newt for instance asks to hide the cursor for
better visual aspect, the kernel puts the vga cursor out of the screen,
so that the cursor position can't be read by the hardware device. This
is a great loss for such people.
Here is a patch which uses the same technique as CUR_NONE for hiding the
cursor while still moving it.
Mario, you should apply it to the speakup kernel for access floppies
asap. I'll submit a 2.4 patch too.

Statically allocated devices in module data is a potential cause
of oopsen. The device may be in use by a userspace process, which
will keep a reference to the device. If the module is unloaded,
the module data will be freed. Subsequent use of the platform
device will cause a kernel oops.
Use generic platform device allocation/release code in modules.

Re-jig the simple platform device support to allow private data
to be attached to a platform device, as well as allowing the
parent device to be set.
Example usage:
pdev = platform_device_alloc("mydev", id);
if (pdev) {
err = platform_device_add_resources(pdev, &resources,
ARRAY_SIZE(resources));
if (err == 0)
err = platform_device_add_data(pdev, &platform_data,
sizeof(platform_data));
if (err == 0)
err = platform_device_add(pdev);
} else {
err = -ENOMEM;
}
if (err)
platform_device_put(pdev);

Adds a phy_mask field to struct mii_bus and uses it. This field
indicates each phy address to be ignored when probing the mdio bus.
This support is needed for the fs_enet and ibm_emac drivers to be
converted to the generic phy layer among other drivers. Many systems
lock up on probing certain phy addresses or probing doesn't return
0xffff when nothing is found at the address. A new driver I'm
working on also makes use of this mask.

This patch is a better fix for Allied Telesyn 2700/2701 FX boards than
the change made in early January this year. It allows the user to
select the speed/duplex via module_param, but if no selection is made,
forces the speed to 100 FD. It fixes both Bugzilla bugs 2669 and 4551.

Display the name eth%d or pci_name() of device which fails to allocate
memory. When changing ring size via ethtool, it also releases the
lock before returning on error. Added comment that the caller of
pcnet32_alloc_ring must call pcnet32_free_ring on error, to avoid leak.

Hi,
This patch provides dynamic two buffer-mode and 3 buffer-mode options.
Previously 2 buffer-mode was compilation option. Now with this patch applied
one can load driver in 2 buffer-mode with module-load parameter
ie.
#insmod s2io.ko rx_ring_mode=2
This patch also provides 3 buffer-mode which provides header separation
functionality. In 3 buffer-mode skb->data will have L2/L3/L4 headers and
"skb_shinfo(skb)->frag_list->data" will have have L4 payload.
one can load driver in 3 buffer-mode with same above module-load parameter
ie.
#insmod s2io.ko rx_ring_mode=3
Please review the patch.
