initramfs ended up depending on BLOCK:
INITRAMFS_SOURCE <-- BLK_DEV_INITRD <-- BLOCK
This inhibits use of customized-initramfs-over-ramfs without block layer
(ramfs would still be enabled), useful in embedded applications.
Move BLK_DEV_INITRD out of 'drivers/block/Kconfig' and into 'init/Kconfig',
make it unconditional.

This patch changes the way we determine if a logical volume is larger than
2TB.
The original test looked for a total_size of 0. Originally we added 1 to the
total_size. That would make our read_capacity return size 0 for >2TB lv's.
We assumed that we could not have a lv size of 0 so it seemed OK until we were
in a clustered system. The backup node would see a size of 0 due to the
reservation on the drive. That caused the driver to switch to 16-byte CDB's
which are not supported on older controllers. After that everything was
broken.
It may seem petty but I don't see the value in trying to determine if the LBA
is beyond the 2TB boundary. That's why when we switch we use 16-byte CDB's
for all read/write operations. Please consider this for inclusion.

The interrupt is shared with another device, which resumes earlier than the
sdhci controller, and generates an interrupt.
The sdhci interrupt handler runs, sees 0xffffffff in its own device's
interrupt status, and tries to handle it.. The reason for the 0xffffffff
is that the device is still suspended, and *all* regs are reading back
0xffffffff.

We were using the platform_device.id field to identify which ethernet
port is used for mv643xx_eth device. This is not generally correct.
It will be incorrect, for example, if a hardware platform uses a single
port but not the first port. Here, we add an explicit port_number field
to struct mv643xx_eth_platform_data.
This makes the mv643xx_eth_platform_data structure required, but that
isn't an issue since all users currently provide it already.

The PCnet32 driver always passed the the size of the largest possible packet
to the pci_dma_sync_single_for_cpu and pci_dma_sync_single_for_device.
This results in a fairly large "colateral damage" in the caches and makes
the flush operation itself much slower. On a system with a 40MHz CPU this
patch increases network bandwidth by about 12%.

enabling interrupts which nobody asks it to do (that has been fixed recently in
a number of drivers) and one unusual, with poll_controller() method possibly
causing loss of interrupts due to the interrupt status register being cleared

In active-backup mode, the current bonding code duplicates IGMP
traffic to all slaves, so that switches are up to date in case of a
failover from an active to a backup interface. If bonding then fails
back to the original active interface, it is likely that the "active
slave" switch's IGMP forwarding for the port will be out of date until
some event occurs to refresh the switch (e.g., a membership query).
This patch alters the behavior of bonding to no longer flood
IGMP to all ports, and to issue IGMP JOINs to the newly active port at
the time of a failover. This insures that switches are kept up to date
for all cases.
"GOELLESCH Niels" <niels.goellesch@eurocontrol.int> originally
reported this problem, and included a patch. His original patch was
modified by Jay Vosburgh to additionally remove the existing IGMP flood
behavior, use RCU, streamline code paths, fix trailing white space, and
adjust for style.

Bonding can erroneously register the same packet_type to receive
ARPs (for use by ARP validation): once at device open time, and once via
sysfs. Since sysfs can change the validate setting (and thus register
or unregister) at any time, a flag is needed to synchronize with device
open in order to avoid double registrations, and the simplest place is
within the packet_type structure itself. Double unregister is not an
issue.

CT based mach64 cards were reported to hang on sparc64 boxes when
compiled with gcc-4.1.x and later.
Looking at this piece of code, it's no surprise. A critical
delay was implemented as an empty for() loop, and gcc 4.0.x
and previous did not optimize it away, so we did get a delay.
But gcc-4.1.x and later can optimize it away, and we get crashes.

This patch resolves the issue found here:
http://bugme.osdl.org/show_bug.cgi?id=7426
The basic summary is:
Currently we register most of i386/x86_64 clocksources at module_init
time. Then we enable clocksource selection at late_initcall time. This
causes some problems for drivers that use gettimeofday for init
calibration routines (specifically the es1968 driver in this case),
where durring module_init, the only clocksource available is the low-res
jiffies clocksource. This may cause slight calibration errors, due to
the small sampling time used.
It should be noted that drivers that require fine grained time may not
function on architectures that do not have better then jiffies
resolution timekeeping (there are a few). However, this does not
discount the reasonable need for such fine-grained timekeeping at init
time.
Thus the solution here is to register clocksources earlier (ideally when
the hardware is being initialized), and then we enable clocksource
selection at fs_initcall (before device_initcall).
This patch should probably get some testing time in -mm, since
clocksource selection is one of the most important issues for correct
timekeeping, and I've only been able to test this on a few of my own
boxes.

Recent patch for raid6 reshape had a change missing that showed up in
subsequent review.
Many places in the raid5 code used "conf->raid_disks-1" to mean "number of
data disks". With raid6 that had to be changed to "conf->raid_disk -
conf->max_degraded" or similar. One place was missed.
This bug means that if a raid6 reshape were aborted in the middle the
recorded position would be wrong. On restart it would either fail (as the
position wasn't on an appropriate boundary) or would leave a section of the
array unreshaped, causing data corruption.

Currently sm501fb_crtsrc_store() won't allow the routing to be changed via
echos from userspace in to the sysfs file. The reason for this is that the
strnicmp() for both heads uses a sizeof() for the string length, which ends
up being strlen() + 1 (\0 in the normal case, but the echo gives a newline,
which is where the issue occurs), this then causes a mismatch and
subsequently bails with the -EINVAL.
In addition to this, the hardcoded lengths were then used for the store
length that was returned, which ended up being erroneous and resulting in a
write error. There's also no point in returning anything but the full
length since it will -EINVAL out on a mismatch well before then anyways.
sizeof("string") is great for making sure you have space in your buffer,
but rather less so for string comparisons :-)

Most drivers using GPIOs already know they are running on a system that
supports the generic GPIO calls, because of other platform dependencies.
But the generic GPIO-based LED and input button drivers can't know that.
So this patch adds a Kconfig hook, GENERIC_GPIO, to mark the platforms
where <asm/gpio.h> will do the right thing. Currently that's a bunch of
ARMs, and AVR32; more are on the way.
It also fixes a dependency bug for the gpio button input driver; it was
wrong to start with, now it covers all platforms with GENERIC_GPIO.

Fix soft lockup with iSeries viocd driver, caused by eventually calling
end_that_request_first() with nr_bytes 0.
Some versions of hald do an SG_IO ioctl on the viocd device which becomes a
request with hard_nr_sectors and hard_cur_sectors set to zero. Passing zero
as the number of sectors to end_request() (which calls
end_that_request_first()) causes an infinite loop when the bio is being freed.
This patch makes sure that the zero is never passed. It only requires some
number larger the the request size the terminate the loop.

For devices that do not support msi-x we only support 1 interrupt. Therefore
we can disable that one interrupt by disabling the msi capability itself. If
we leave the intx interrupts disabled while we have the msi capability
disabled no interrupts should be delivered from that device.
Devices with just the minimal msi support (and thus hitting this code path)
include things like the intel e1000 nic, so it looks like is going to be a
fairly common case and thus important to get right.

enable/disable_msi_mode have several side effects which keeps them from being
generally useful. So this patch replaces them with with two much more
targeted functions: msi_set_enable and msix_set_enable.
This patch makes pci_dev->msi_enabled and pci_dev->msix_enabled the definitive
way to test if linux has enabled the msi capability, and has the appropriate
msi data structures set up.
This patch ensures that while writing the msi messages in save/restore and
during device initialization we have the msi capability disabled so we don't
get into races. The pci spec requires that we do not have the msi capability
enabled and the msi messages unmasked while we write the messages. Completely
disabling the capability is overkill but it is easy :)
Care has been taken so we never have both a msi capability and intx enabled
simultaneously. We haven't run into a problem yet but better safe then sorry.

In some cases when we are not using msi we need a way to ensure that the
hardware does not have an msi capability enabled. Currently the code has been
calling disable_msi_mode to try and achieve that. However disable_msi_mode
has several other side effects and is only available when msi support is
compiled in so it isn't really appropriate.
Instead this patch implements pci_msi_off which disables all msi and msix
capabilities unconditionally with no additional side effects.
pci_disable_device was redundantly clearing the bus master enable flag and
clearing the msi enable bit. A device that is not allowed to perform bus
mastering operations cannot generate intx or msi interrupt messages as those
are essentially a special case of dma, and require bus mastering. So the call
in pci_disable_device to disable msi capabilities was redundant.
quirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off.
