Patch from Ben Dooks

Fix the idle code on the s3c2412 as the default
code is using bits in the CLKCON register that are
no-longer there.

Provide an override for the idle code, and ensure
that the power configuration is set to allow idle
instead of stop or sleep.

Patch from Ben Dooks

These two machines are identical, and supported
by the SMDK2413 configuration. When MACH_SMDK2413
is selected, we must also select MACH_S3C2413
to allow machine_is_smdk2413() or machine_is_s3c2413()
to work.

* 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/paulus/powerpc:
  [POWERPC] Fix G5 DART (IOMMU) race causing occasional data corruption
  [POWERPC] Fix MMIO ops to provide expected barrier behaviour
  [POWERPC] Fix interrupt clearing in kdump shutdown sequence
  [POWERPC] update prep_defconfig
  [POWERPC] kdump: Support kernels having 64k page size.
  [POWERPC] Implement PowerPC futex_atomic_cmpxchg_inatomic().
  [POWERPC] Add new, missing argument to of_irq_map_raw() for 86xx.
  [POWERPC] Update defconfigs

Add support for new hardware and bumps the version to 3.6.10.  It seems
there were several changes introduced including soft_irq.  I decided to
bump the major number to reflect these changes.  Since we're still
supporting older vendor kernels I need some way differentiate between
kernel versions <=2.6.10 and newer kernels >=2.6.16.

MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, which
doesn't exist in userspace.  Move an #endif /* __KERNEL__ */ down a few lines
to prevent that.

Also, remove the broken definition of PAGE_SIZE which is never going to be
correct -- in the absence of PAGE_SIZE, non-broken userspace will fall back to
using sysconf() or getpagesize() instead.

Some files which don't exist in userspace were being included unconditionally

they're protected by #ifdef __KERNEL__

In fact, we probably want to kill off all userspace use of asm/elf.h -- but we
aren't there yet, so we should at least make it possible to include it for
now.

There's useful stuff in <linux/timex.h> but <asm/timex.h> has nothing for
userspace.  Stop exporting it, and include it only from within the existing
#ifdef __KERNEL__ part of <linux/timex.h>

This fixes a 'make headers_check' failure on i386 because asm-i386/timex.h
includes both asm-i386/tsc.h and asm-i386/processor.h, neither of which are
exported to userspace.  It's not entirely clear _why_ it includes either of
these, but it does.

We don't need any of this crap included from the user-visible part of nfs_fs.h
-- remove it all.

In fact, we probably don't need anything but NFS_SUPER_MAGIC to be defined; is
there any need for anything else?  And magic numbers should probably move to
<linux/magic.h> rather than being strewn across various fs-specific include
files which exist in userspace for solely that purpose.

With this patch, 'make header_check' works again at least on PowerPC.

It seems that the occasional data corruption observed with the tg3
driver wasn't due to missing barriers after all, but rather seems to
be due to the DART (= IOMMU) in the U4 northbridge reading stale
IOMMU table entries from memory due to a race.  This fixes it by
making the CPU read the entry back from memory before using it.

This changes the writeX family of functions to have a sync instruction
before the MMIO store rather than after, because the generally expected
behaviour is that the device receiving the MMIO store can be guaranteed
to see the effects of any preceding writes to normal memory.

To preserve ordering between writeX and readX, and to preserve ordering
between preceding stores and the readX, the readX family of functions
have had an sync added before the load.

Although writeX followed by spin_unlock is not officially guaranteed
to keep the writeX inside the spin-locked region unless an mmiowb()
is used, there are currently drivers that depend on the previous
behaviour on powerpc, which was that the mmiowb wasn't actually required.
Therefore we have a per-cpu flag that is set by writeX, cleared by
__raw_spin_lock and mmiowb, and tested by __raw_spin_unlock.  If it is
set, __raw_spin_unlock does a sync and clears it.

This changes both 32-bit and 64-bit readX/writeX.  32-bit already has a
sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus
doesn't need the per-cpu flag.

Tested on G5 (PPC970) and POWER5.

This is required to generate proper core files using kdump on ppc64.

Create a backup region of 64K size irrespective of the PAGE SIZE.
At present 32K was used as backup size. In the case of 64K page size,
second PT_LOAD segments starts at 32K and the first one is not page
aligned.  __ioremap() (crash_dump.c) fails if pfn = 0 which is the
case for the second PT_LOAD segment. This is not an issue for 4K page
size because the the first page (32K backup) is copied to second
kernel memory and thus referencing with the second kernel pfn.
