b3f2f6cd1f ia64: revert __node_random addition
This partially reverts commit 4ec37de89d
("[IA64] Fix build breakage"), since the commit that made it necessary
got reverted earlier (see commit 35926ff5fb, 'Revert "cpusets:
randomize node rotor used in cpuset_mem_spread_node()"')

Even if we ever re-introduce this, there is no reason to make
__node_random be some architecture-specific function.

35926ff5fb Revert "cpusets: randomize node rotor used in cpuset_mem_spread_node()"
This reverts commit 0ac0c0d0f8, which
caused cross-architecture build problems for all the wrong reasons.
IA64 already added its own version of __node_random(), but the fact is,
there is nothing architectural about the function, and the original
commit was just badly done. Revert it, since no fix is forthcoming.

210501aa57 parisc: Call pagefault_disable/pagefault_enable in kmap_atomic/kunmap_atomic
Based on the generic implementation of kmap_atomic and kunmap_atomic,
we should call pagefault_disable and pagefault_enable in our PA8000
implementation.

The define for kmap_atomic_prot was also missing, and I updated
kmap_atomic_pfn to use the generic implementation because of the
change to kmap_atomic.

I believe that this change is needed to fix the fork copy-on-write
bug.

8507bb0062 FRV: ARCH_KMALLOC_MINALIGN was already defined
ARCH_KMALLOC_MINALIGN was already defined in asm/mem-layout.h and so shouldn't
have been added to asm/cache.h as well, but rather altered in place.

The commit that added it to asm/cache.h was:

	commit 69dcf3db03
	Author: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp>
	Date:   Mon May 24 14:32:54 2010 -0700

	    frv: set ARCH_KMALLOC_MINALIGN

	    Architectures that handle DMA-non-coherent memory need to set
	    ARCH_KMALLOC_MINALIGN to make sure that kmalloc'ed buffer is
	    DMA-safe: the buffer doesn't share a cache with the others.

1b061d9247 rename the generic fsync implementations
We don't name our generic fsync implementations very well currently.
The no-op implementation for in-memory filesystems currently is called
simple_sync_file which doesn't make too much sense to start with,
the the generic one for simple filesystems is called simple_fsync
which can lead to some confusion.

This patch renames the generic file fsync method to generic_file_fsync
to match the other generic_file_* routines it is supposed to be used
with, and the no-op implementation to noop_fsync to make it obvious
what to expect.  In addition add some documentation for both methods.

TS_POLLING clear tells resched_task() and wake_up_idle_cpu()

and thus requires a reschedule interrupt notice work.

Add a new driver to support the AB8500 Power Management chip, replacing
the current AB4500.  The new driver replaces the old one, instead of an
incremental modification, because this is a substantial overhaul
including:

 - Split of the driver into -core and -spi portions, to allow another
   interface layer to be added

 - Addition of interrupt support

 - Switch to MFD core API for handling subdevices

 - Simplification of the APIs to remove a redundant block parameter

 - Rename of the APIs and macros from ab4500_* to ab8500_*

 - Rename of the files from ab4500* to ab8500*

 - Change of the driver name from ab4500 to ab8500

1ba4f22c42 x86, cpufeature: Unbreak compile with gcc 3.x
gcc 3 is too braindamaged to be able to compile static_cpu_has() --
apparently it can't tell that a constant passed to an inline function
is still a constant -- so if we're using gcc 3, just use the dynamic
test.  This is bad for performance, but if you care about performance,
don't use an ancient, known-to-optimize-poorly compiler.
