26-eeh-partition-endpoint.patch

New versions of firmware introduce a new method by which the
"partitionable endpoint" (the point at which the pci bus is cut)
should be located.  This code adds the support for this (mandatory)
new feature.

25-pci-address-cache.patch

The core EEH file is rather large. This patch splits out a self-contained
chunk of it into its own file.  This is the chunk that performes the
caching and lookup of pci devices based on the i/o addresses of thier
resoures.  This code is almos architecture-independent and could be
used by any system that wanted to find a pci device based only on
the i/o address used by the device.

Various PCI bus errors can be signaled by newer PCI controllers.  The
core error recovery routines are architecture dependent.  This patch adds
a recovery infrastructure for the  PPC64 pSeries systems.

I think it is better to set ->next_pending in the caller, when
it is needed. This saves one parameter, and this coincides with
cpu_quiet() beahaviour, which sets ->completed = ->cur itself.

Semaphores are currently being used where it makes more sense for

This patch converts the inode semaphore to a mutex. I have tested it on

This patch switches XFS over to use the new mutex code directly as
opposed to the previous workaround patch I posted earlier that avoided
the namespace clash by forcing it back to semaphores. This falls in the
'works for me<tm>' category.

add the per-arch mutex.h files for the remaining architectures.

We default to asm-generic/mutex-dec.h, because that performs
quite well on most arches. Arches that do not have atomic
decrement/increment instructions should switch to mutex-xchg.h
instead. Arches can also provide their own implementation for
the mutex fastpath primitives.

Signed-off-by: Ingo Molnar <mingo@elte.hu>

Add three (generic) mutex fastpath implementations.

The mutex-xchg.h implementation is atomic_xchg() based, and should
work fine on every architecture.

The mutex-dec.h implementation is atomic_dec_return() based - this
one too should work on every architecture, but might not perform the
most optimally on architectures that have no atomic-dec/inc instructions.

The mutex-null.h implementation forces all calls into the slowpath. This
is used for mutex debugging, but it can also be used on platforms that do
not want (or need) a fastpath at all.
