When two md arrays share some block device (e.g each uses different
partitions on the one device), a resync of one array will wait for
the resync on the other to finish.
This can be a long time and as it currently waits TASK_UNINTERRUPTIBLE,
the softlockup code notices and complains.
So use TASK_INTERRUPTIBLE instead and make sure to flush signals
before calling schedule.

Currently e100 uses pci_enable_wake() to clear pending wake-up events
and disable PME# during intitialization, but that function is not
suitable for this purpose, because it immediately returns error code
if device_may_wakeup() returns false for given device.
Make e100 use pci_pme_active(), which carries out exactly the
required operations, instead.

The EEPROM corruption is triggered by concurrent access of the EEPROM

The bnx2 driver stores/uses the irq value from the pci_dev internally.
But when it stores the irq value, it has been performing an
integer demotion. Because of the recent changes made to
arch/x86/kernel/io_apic.c, the new method in creating the irq value
(using build_irq_for_pci_dev()) has exposed this bug on x86 systems.
Because of this demotion when calling request_irq() from
bnx2_request_irq(), the driver would get a return code of -EINVAL.
This is because the kernel could not find the requested irq descriptor.
By storing the irq value properly, the kernel can find the correct
irq descriptor and the bnx2 driver can operate normally.

ProHG media is more sensitive to the ordering of initialization
commands.
- Make the driver fall back to highest supported mode instead of always
falling back to serial. The driver will attempt the switch to 8b mode
for any new MSPro card, but not all of them support it. Previously,
these new cards ended up in serial mode, which is not the best idea
(they work fine with 4b, after all).

When suspending the system with atmel_lcdfb enabled, I sometimes see
this:
atmel_lcdfb atmel_lcdfb.0: FIFO underflow 0x10
Which can be explained by the fact that we're not stopping the LCD
controller and its DMA engine when suspending, we're just gating the
clocks to them.
There's another potential issue which may be harder to trigger but
much more nasty: If we gate the clocks at _just_ the right moment,
e.g. when the DMA engine is doing a bus transaction, we may cause the
DMA engine to violate the system bus protocol and cause a lockup.
Avoid these issues by shutting down the LCD controller before entering
suspend (and restarting it when resuming). This prevents the underrun
from happening in the first place, and prevents whatever nastiness is
happening when the bus clock stops in the middle of a DMA transfer.

If you are on ia64 and you modprobe xpc then modprobe -r xpc, you
immediately get a panic. xpc depends on xp which depends on gru for a
symbol. That symbol is only used when we are running on UV hardware.
Currently, the GRU driver detects we are not on UV hardware and does no
initializing. It does not do the same check when unloading. As a result,
the gru driver attempts to tear down stuff that was not setup.
This is a simple two-line workaround to get us through this release. Once
2.6.28 is opened, we need to rework the symbols that xp is depending on
from gru so the gru driver can properly fail to load when hardware is not
available.

Fixes two DMA bugs in the pxa2xx_spi driver. The first bug is in all
versions of this driver; the second was introduced in the 2.6.20 kernel,
and prevents using the driver with chips like m25p16 flash (which can
issue large DMA reads).
1. Zero length transfers are permitted for use to insert timing,
but pxa2xx_spi.c will fail if this is requested in DMA mode.
Fixed by using programmed I/O (PIO) mode for such transfers.
2. Transfers larger than 8191 are not permitted in DMA mode. A
test for length rejects all large transfers regardless of DMA
or PIO mode. Worked around by rejecting only large transfers
with DMA mapped buffers, and forcing all other transfers
larger than 8191 to use PIO mode. A rate limited warning is
issued for DMA transfers forced to PIO mode.
This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20. An additional patch would be
required for older kernels, but those versions are very buggy anyway.

Fixes several chipselect bugs in the pxa2xx_spi driver. These bugs are in
all versions of this driver and prevent using it with chips like m25p16
flash.
1. The spi_transfer.cs_change flag is handled too early:
before spi_transfer.delay_usecs applies, thus making the
delay ineffective at holding chip select.
2. spi_transfer.delay_usecs is ignored on the last transfer
of a message (likewise not holding chipselect long enough).
3. If spi_transfer.cs_change is set on the last transfer, the
chip select is always disabled, instead of the intended
meaning: optionally holding chip select enabled for the
next message.
Those first three bugs were fixed with a relocation of delays
and chip select de-assertions.
4. If a message has the cs_change flag set on the last transfer,
and had the chip select stayed enabled as requested (see 3,
above), it would not have been disabled if the next message is
for a different chip. Fixed by dropping chip select regardless
of cs_change at end of a message, if there is no next message
or if the next message is for a different chip.
This patch should apply to all kernels back to and including 2.6.20;
it was test patched against 2.6.20. An additional patch would be
required for older kernels, but those versions are very buggy anyway.

git commit 74811f355f causes crash at
module load (or boot) time on my machine with a hpt374 controller.
The reason for this is that for initializing second controller which sets
(hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
Because of this, all initialization functions get corrupted data in info
variable which causes a crash at boot time.
This patch fixes that and makes my machine boot again.
