ehea: add kdump support
This patch adds kdump support to the ehea driver. As the firmware doesn't free
resource handles automatically, the driver has to run an as simple as possible
free resource function in case of a crash shutdown. The function iterates over
two arrays freeing all resource handles which are stored there. The arrays are
kept up-to-date during normal runtime. The crash handler fn is triggered by the
recently introduced PPC crash shutdown reg/unreg functions.

Add memory barrier semantics to wake_up() & co
Oleg Nesterov and others have pointed out that on some architectures,
the traditional sequence of
set_current_state(TASK_INTERRUPTIBLE);
if (CONDITION)
return;
schedule();
is racy wrt another CPU doing
CONDITION = 1;
wake_up_process(p);
because while set_current_state() has a memory barrier separating
setting of the TASK_INTERRUPTIBLE state from reading of the CONDITION
variable, there is no such memory barrier on the wakeup side.
Now, wake_up_process() does actually take a spinlock before it reads and
sets the task state on the waking side, and on x86 (and many other
architectures) that spinlock is in fact equivalent to a memory barrier,
but that is not generally guaranteed. The write that sets CONDITION
could move into the critical region protected by the runqueue spinlock.
However, adding a smp_wmb() to before the spinlock should now order the
writing of CONDITION wrt the lock itself, which in turn is ordered wrt
the accesses within the spinlock (which includes the reading of the old
state).
This should thus close the race (which probably has never been seen in
practice, but since smp_wmb() is a no-op on x86, it's not like this will
make anything worse either on the most common architecture where the
spinlock already gave the required protection).

The errors are "Use of uninitialized value in concatenation (.)..."
in combination with:
Warning(linux-2.6.25-rc2/block/blk-core.c:1877): No description found for parameter ''

The compiler is happy with them, but kernel-doc isn't.
This patch teaches create_parameterlist in kernel-doc to parse this type of

The problem only seems to occur in blk-core.c.
However with the patch applied, kernel-doc finds the correct parameter
description for the callback in blk_end_request_callback, which is doesn't
normally.
I thought it would be a bit odd to change to code to use the more normal

kernel-doc instead - even though this is teaching it to understand code
that might go away (The comment for blk_end_request_callback says that it

futex: runtime enable pi and robust functionality
Not all architectures implement futex_atomic_cmpxchg_inatomic(). The default
implementation returns -ENOSYS, which is currently not handled inside of the
futex guts.
Futex PI calls and robust list exits with a held futex result in an endless
loop in the futex code on architectures which have no support.
Fixing up every place where futex_atomic_cmpxchg_inatomic() is called would
add a fair amount of extra if/else constructs to the already complex code. It
is also not possible to disable the robust feature before user space tries to
register robust lists.
Compile time disabling is not a good idea either, as there are already
architectures with runtime detection of futex_atomic_cmpxchg_inatomic support.
Detect the functionality at runtime instead by calling
cmpxchg_futex_value_locked() with a NULL pointer from the futex initialization
code. This is guaranteed to fail, but the call of
futex_atomic_cmpxchg_inatomic() happens with pagefaults disabled.
On architectures, which use the asm-generic implementation or have a runtime
CPU feature detection, a -ENOSYS return value disables the PI/robust features.
On architectures with a working implementation the call returns -EFAULT and
the PI/robust features are enabled.
The relevant syscalls return -ENOSYS and the robust list exit code is blocked,
when the detection fails.

uml: fix FP register corruption
Commit
ee3d9bd4de1ed93d2a7ee41c331ed30a1c7b8acd ("uml: simplify SIGSEGV
handling"), while greatly simplifying the kernel SIGSEGV handler that
runs in the process address space, introduced a bug which corrupts FP
state in the process.
Previously, the SIGSEGV handler called the sigreturn system call by hand - it
couldn't return through the restorer provided to it because that could try to
call the libc restorer which likely wouldn't exist in the process address
space. So, it blocked off some signals, including SIGUSR1, on entry to the
SIGSEGV handler, queued a SIGUSR1 to itself, and invoked sigreturn. The
SIGUSR1 was delivered, and was visible to the UML kernel after sigreturn
finished.
The commit eliminated the signal masking and the call to sigreturn. The
handler simply hits itself with a SIGTRAP to let the UML kernel know that it
is finished. UML then restores the process registers, which effectively
longjmps the process out of the signal handler, skipping sigreturn's restoring
of register state and the signal mask.
The bug is that the host apparently sets used_fp to 0 when it saves the
process FP state in the sigcontext on the process signal stack. Thus, when
the process is longjmped out of the handler, its FP state is corrupt because
it wasn't saved on the context switch to the UML kernel.
This manifested itself as sleep hanging. For some reason, sleep uses floating
point in order to calculate the sleep interval. When a page fault corrupts
its FP state, it is faked into essentially sleeping forever.
This patch saves the FP state before entering the SIGSEGV handler and restores
it afterwards.

spi: pxa2xx_spi clock polarity fix
Fixes a sequencing bug in spi driver pxa2xx_spi.c in which the chip select
for a transfer may be asserted before the clock polarity is set on the
interface. As a result of this bug, the clock signal may have the wrong
polarity at transfer start, so it may need to make an extra half transition
before the intended clock/data signals begin. (This probably means all
transfers are one bit out of sequence.)
This only occurs on the first transfer following a change in clock polarity
in systems using more than one more than one such polarity. The fix
assures that the clock mode is properly set before asserting chip select.
This bug was introduced in a patch merged on 2006/12/10, kernel 2.6.20.
The patch defines an additional bit in: include/asm-arm/arch-pxa/regs-ssp.h
for 2.6.25 and newer kernels but this addition must be made in:
include/asm-arm/arch-pxa/pxa-regs.h for kernels between 2.6.20 and 2.6.24,

atmel_spi: fix clock polarity
The atmel_spi driver does not initialize clock polarity correctly (except for
at91rm9200 CS0 channel) in some case.
The atmel_spi driver uses gpio-controlled chipselect. OTOH spi clock signal
is controlled by CSRn.CPOL bit, but this register controls clock signal
correctly only in 'real transfer' duration. At the time of cs_activate()
call, CSRn.CPOL will be initialized correctly, but the controller do not know
which channel is to be used next, so clock signal will stay at the inactive
state of last transfer. If clock polarity of new transfer and last transfer
was differ, new transfer will start with wrong clock signal state.
For example, if you started SPI MODE 2 or 3 transfer after SPI MODE 0 or 1
transfer, the clock signal state at the assertion of chipselect will be low.
Of course this will violates SPI transfer.
This patch is short term solution for this problem. It makes all CSRn.CPOL
match for the transfer before activating chipselect. For longer term, the
best fix might be to let NPCS0 stay selected permanently in MR and overwrite
CSR0 with to the new slave's settings before asserting CS.

fuse: fix permission checking
I added a nasty local variable shadowing bug to fuse in 2.6.24, with the
result, that the 'default_permissions' mount option is basically ignored.
How did this happen?
- old err declaration in inner scope
- new err getting declared in outer scope
- 'return err' from inner scope getting removed
- old declaration not being noticed
-Wshadow would have saved us, but it doesn't seem practical for
the kernel :(

percpu: fix DEBUG_PREEMPT per_cpu checking
2.6.25-rc1 percpu changes broke CONFIG_DEBUG_PREEMPT's per_cpu checking
on several architectures. On s390, sparc64 and x86 it's been weakened to
not checking at all; whereas on powerpc64 it's become too strict, issuing
warnings from __raw_get_cpu_var in io_schedule and init_timer for example.
Fix this by weakening powerpc's __my_cpu_offset to use the non-checking
local_paca instead of get_paca (which itself contains such a check);
and strengthening the generic my_cpu_offset to go the old slow way via
smp_processor_id when CONFIG_DEBUG_PREEMPT (debug_smp_processor_id is
where all the knowledge of what's correct when lives).

PM: Introduce PM_EVENT_HIBERNATE callback state
During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.
But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.
For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate. Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.
These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

[SCSI] stex: stex_direct_copy shouldn't call dma_map_sg
stex_direct_copy copies an in-kernel buffer to a sg list in order to

stex_internal_copy with the value that dma_map_sg returned. It calls
scsi_kmap_atomic_sg to copy data.
scsi_kmap_atomic_sg doesn't see sg->dma_length so if dma_map_sg merges
sg entries, stex_internal_copy gets the smaller number of sg entries

length in the sg list is shorter than the actual length.
stex_direct_copy shouldn't call dma_map_sg and it doesn't need since

stex_direct_copy and simply calls stex_internal_copy with the actual

[SCSI] libsas: fix error handling
The libsas error handler has two fairly fatal bugs
1. scsi_sas_task_done calls scsi_eh_finish_cmd() too early. This
happens if the task completes after it has been aborted but before
the error handler starts up. Because scsi_eh_finish_cmd()
decrements host_failed and adds the task to the done list, the
error handler start check (host_failed == host_busy) never passes
and the eh never starts.
2. The multiple task completion paths sas_scsi_clear_queue_... all
simply delete the task from the error queue. This causes it to
disappear into the ether, since a command must be placed on the
done queue to be finished off by the error handler. This behaviour
causes the HBA to hang on pending commands.
Fix 1. by moving the SAS_TASK_STATE_ABORTED check to an exit clause at
the top of the routine and calling ->scsi_done() unconditionally (it
is a nop if the timer has fired). This keeps the task in the error
handling queue until the eh starts.
Fix 2. by making sure every task goes through task complete followed
by scsi_eh_finish_cmd().
Tested this by firing resets across a disk running a hammer test (now
it actually survives without hanging the system)
