Instead of removing removing the #endif at the end of the file,
the #endif before #else should have been removed.
But we cannot have multiple #else statements as pointed out by
Alistair Buxton <a.j.buxton@gmail.com>. So the fix is to:
- remove the non-multi-omap special handling, as we need to
detect between omap730 and omap850 anyways.
- add the missing #endif back to the end of the file

Rich reported a lock imbalance in the futex code:
http://bugzilla.kernel.org/show_bug.cgi?id=14288
It's caused by the displacement of the retry_private label in
futex_wake_op(). The code unlocks the hash bucket locks in the
error handling path and retries without locking them again which
makes the next unlock fail.
Move retry_private so we lock the hash bucket locks when we retry.

The rcu_barrier enum causes several problems:
(1) you have to define the enum somewhere, and there is no
convenient place,
(2) the difference between TREE_RCU and TREE_PREEMPT_RCU causes
problems when you need to map from rcu_barrier enum to struct
rcu_state,
(3) the switch statement are large, and
(4) TINY_RCU really needs a different rcu_barrier() than do the
treercu implementations.
So replace it with a functionally equivalent but cleaner function
pointer abstraction.

These issues identified during an old-fashioned face-to-face code
review extending over many hours. This group improves an existing
abstraction and introduces two new ones. It also fixes an RCU
stall-warning bug found while making the other changes.
o Make RCU_INIT_FLAVOR() declare its own variables, removing
the need to declare them at each call site.
o Create an rcu_for_each_leaf() macro that scans the leaf
nodes of the rcu_node tree.
o Create an rcu_for_each_node_breadth_first() macro that does
a breadth-first traversal of the rcu_node tree, AKA
stepping through the array in index-number order.
o If all CPUs corresponding to a given leaf rcu_node
structure go offline, then any tasks queued on that leaf
will be moved to the root rcu_node structure. Therefore,
the stall-warning code must dump out tasks queued on the
root rcu_node structure as well as those queued on the leaf
rcu_node structures.

Currently, only GPIOs in the wakeup domain (GPIOs in bank 0) are
enabled as wakups. This patch also enables GPIOs in the PER
powerdomain (banks 2-6) to be used as possible wakeup sources.
In addition, this patch ensures that all GPIO wakeups can wakeup
the MPU using the PM_MPUGRPSEL_<pwrdm> registers.
NOTE: this doesn't enable the individual GPIOs as wakeups, this simply
enables the per-bank wakeups at the powerdomain level.
This problem was discovered by Mike Chan when preventing the CORE
powerdomain from going into retention/off. When CORE was allowed to
hit retention, GPIO wakeups via IO pad were working fine, but when
CORE remained on, GPIO module-level wakeups were not working properly.
To test, prevent CORE from going inactive/retention/off, thus
preventing the IO chain from being armed:
# echo 3 > /debug/pm_debug/core_pwrdm/suspend
This ensures that GPIO wakeups happen via module-level wakeups and
not via IO pad.
Tested on 3430SDP using the touchscreen GPIO (gpio 2, in WKUP)
Tested on Zoom2 using the QUART interrup GPIO (gpio 102, in PER)

wakeup event to ensure both hosts can properly clear the event.

Clearing wakeup sources is now only done when the PRM indicates a

PRCM interrupts right now, warn if we get any other type of PRCM
interrupt. Either code needs to be added to the PRCM interrupt
handler to react to these, or these other interrupts should be masked
off at init.

PM_WKST register contents should be ANDed with the contents of the
MPUGRPSEL registers. Otherwise the MPU PRCM interrupt handler could
wind up clearing wakeup events meant for the IVA PRCM interrupt
handler. A future revision to this code should be to read a cached
version of MPUGRPSEL from the powerdomain code, since PRM reads are
relatively slow.

There are two scenarios where a race condition could result in a hang
in the prcm_interrupt handler. These are:
1). Waiting for PRM_IRQSTATUS_MPU register to clear.
Bit 0 of the PRM_IRQSTATUS_MPU register indicates that a wake-up event
is pending for the MPU. This bit can only be cleared if the all the
wake-up events latched in the various PM_WKST_x registers have been
cleared. If a wake-up event occurred during the processing of the prcm
interrupt handler, after the corresponding PM_WKST_x register was
checked but before the PRM_IRQSTATUS_MPU was cleared, then the CPU
would be stuck forever waiting for bit 0 in PRM_IRQSTATUS_MPU to be
cleared.
2). Waiting for the PM_WKST_x register to clear.
Some power domains have more than one wake-up source. The PM_WKST_x
registers indicate the source of a wake-up event and need to be cleared
after a wake-up event occurs. When the PM_WKST_x registers are read and
before they are cleared, it is possible that another wake-up event
could occur causing another bit to be set in one of the PM_WKST_x
registers. If this did occur after reading a PM_WKST_x register then
the CPU would miss this event and get stuck forever in a loop waiting
for that PM_WKST_x register to clear.
This patch address the above race conditions that would result in a
hang.

According to the following in arch/arm/mm/fault.c page faults from
kernel mode are invalid if mmap_sem is already held and there is
no exception handler defined for the faulting instruction:
/*
* As per x86, we may deadlock here. However, since the kernel only
* validly references user space from well defined areas of the code,
* we can bug out early if this is from code which shouldn't.
*/
if (!down_read_trylock(&mm->mmap_sem)) {
if (!user_mode(regs) && !search_exception_tables(regs->ARM_pc))
goto no_context;
Since mmap_sem can be held at arbitrary times by another thread this
also means that any page faults from kernel mode are invalid if no
exception handler is defined for them, regardless whether mmap_sem is
held at the time of fault.
To easier detect code that can trigger the above error, add a check
also for the case where mmap_sem is acquired. As this has an overhead
make it a VM debug check.

The btrfs async worker threads are used for a wide variety of things,
including processing bio end_io functions. This means that when
the endio threads aren't running, the rest of the FS isn't
able to do the final processing required to clear PageWriteback.
The endio threads also try to exit as they become idle and
start more as the work piles up. The problem is that starting more
threads means kthreadd may need to allocate ram, and that allocation
may wait until the global number of writeback pages on the system is
below a certain limit.
The result of that throttling is that end IO threads wait on
kthreadd, who is waiting on IO to end, which will never happen.
This commit fixes the deadlock by handing off thread startup to a
dedicated thread. It also fixes a bug where the on-demand thread
creation was creating far too many threads because it didn't take into
account threads being started by other procs.

This ends up with the doubled initialization of the same mixer widget,
and it mutes the DAC route because hp_pins has no DAC assigned.
To fix this problem, just check spec->autocfg.hp_outs and speaker_outs

There appears to have been a mixup in the max supported jumbo frame size
between 82574 and 82583 which ended up disabling jumbo frames on the 82574
as a result. This patch swaps the two so that this issue is resolved.

This patch will add support for the 82599 Dual port Backplane
device (0x10f8). This device has the ability to link in serial (KR) and
parallel (KX4/KX) modes, depending on what the switch capabilities are in
the blade chassis.

This reverts commit 6029336426.
Based upon a report by David Fries, wherein his system hangs
on bootup with sis5513 controller, right after the CDROM
is registered by ide-cd.c and the TOC is first read.

I'm skipping -rc2 because the -rc1 Makefile mistakenly said -rc2, so in
order to avoid confusion, I'm jumping from -rc1 to -rc3. That way, when
'uname' (or an oops report) says 2.6.32-rc2, there's no confusion about
whether people perhaps meant -rc1 or -rc2.
This adds support for the setcmap api and fixes the 8bpp
support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.
