Based on an original patch by Valentine Barshak <vbarshak@ru.mvista.com>
Use preempt_schedule_irq to prevent infinite irq-entry and
eventual stack overflow problems with fast-paced IRQ sources.
This kind of problems has been observed on the PASemi Electra IDE
controller. We have to make sure we are soft-disabled before calling
preempt_schedule_irq and hard disable interrupts after that
to avoid unrecoverable exceptions.
This patch also moves the "clrrdi r9,r1,THREAD_SHIFT" out of
the #ifdef CONFIG_PPC_BOOK3E scope, since r9 is clobbered
and has to be restored in both cases.

The creation of the flattened device tree depended on the compiler
putting the constant strings for an object in a section with a
particular name. This was changed with recent compilers. Do this
explicitly instead.
Without this patch, iseries kernels may silently not boot when built with
some compilers.

The architecture defines that if MSR PR is set we are in problem state
irrespective of the HV bit. This fixes perf events to reflect this.
Also, on bare metal systems, samples taken in Linux will now be reported
as kernel rather than hypervisor.

Right now when calling schedule_on_each_cpu() from keventd there
is a deadlock because it tries to schedule a work item on the current CPU
too. This happens via lru_add_drain_all() in hwpoison.
Just call the function for the current CPU in this case. This is actually
faster too.

Memory failure on a KSM page currently oopses on its NULL anon_vma in

Right now we have some trouble with non atomic access
to page flags when locking the page. To plug this hole
for now, limit error recovery to LRU pages for now.
This could be better fixed by defining a suitable protocol,
but let's go this simple way for now
This avoids unnecessary races with __set_page_locked() and
__SetPageSlab*() and maybe more non-atomic page flag operations.
This loses isolated pages which are currently in page reclaim, but these
are relatively limited compared to the total memory.

- Define symbolic names for all the different values
- Boundary check the kill mode values
- For symmetry add a get interface too. This allows library
code to get/set the current state.

xfs_dqrele_inode calls xfs_iput to release the ilock and a reference
and then also calls IRELE which does a second decrement of the reference
count. This leads to a premature freeing of inodes when quotas were turned
off while the filesystem was mounted.

UART3 is in the PER powerdomain. If PER goes idle/inactive
independently of CORE, for UART3 to wakeup it must have its wakeup
enable bits setup in PM_WKEN_PER. This patch enables these bits.
The reason it works when PER and CORE work together is because when
CORE goes inactive/retention, the IOPAD wakeups are enabled and
trigger UART3 wakeup.
Without this patch, when the UART inactivity timer fires for UART3,
its clocks are disabled and it's unable to wakeup so will be unusable
until PER is awoken by another source.
Another way of testing is by keeping CORE on during suspend but
allowing PER to hit retention
# echo 3 > /debug/pm_debug/core_pwrdm/suspend
then enter suspend
# echo mem > /sys/power/state
Without this patch, UART3 will be unable to wakeup the system.

DSP public peripherals used to work on OMAP1510 based (or all OMAP1 class?)
machines as long as old dspgateway code were present in the l-o tree. For
several months it is no longer included, breaking support for McBSP1 based
audio on Amstrad Delta, for example.
This patch, derived from the old dspgateway code, corrects the problem for the
board by simply taking the DSP out of reset state, I guess. That way, things
should not break when a new dsp code is added to the tree, and the change can
be reverted then.
If there are any reports on McBSP1 or other DSP public peripherals not working
for other OMAP1 machines (I've not heard of any for now), I can prepare a more
general patch providing an extra include file with a helper function defined.

Commit 15ac408ee5a509053a765b816e9179515329369f removed enabled_uart
and OMAP_TAG_UART. This works for mach-omap2, but causes issues on
mach-omap1 for some boards as the mach-omap1 serial.c was muxing
pins based on the enabled_uart flag for 15xx.
Fix this by muxing pins in board-*.c files for the 15xx boards for
the uart ports that had enabled_uart flag set before the commit
above.
Tested on Amsdtrad Delta only.
Note that in the future we should add support for powering down
the uarts with a timer like mach-omap2/serial.c does. Otherwise
the enabled uarts will be blocking retention-while-idle.

OMAP sDMA driver API omap_stop_dma() doesn't really stop the dma when used
in linking scenario.
The DMA channel needs to be disabled before resetting the chain.
Also fix clearing of the OMAP_DMA_ACTIVE status in the linked case.

Commit 32bc4820287a1a03982979515949e8ea56eac641 did not fully fix
the backward compatibility issues. We still fail to properly handle
situations when the first PEB contains non-zero image sequence
number, but one of the following PEBs contains zero image sequence
number. For example, this may happen if we mount a new image with
an old kernel, and then try to mount it in the new kernel.
This patch should fix the issue.

Comparing apples to bananas doesn't seem right. Consistently use the
chips enum for chip type comparisons, to avoid such bugs in the
future.
The bug has been there since support for the IT8718F was added, so
VID never worked for this chip nor for the similar IT8720F.

The SCH311x chips do not have VID inputs, so the cpu0_vid and vrm
attributes shouldn't be created for them.
