02ed82ccc5 [POWERPC] 85xx: Drop use of SYNC macro in head_fsl_booke.S
Eliminate needless invocation of the SYNC macro (which always evaluates to
nothing on BookE) from head_fsl_booke.S (for both arch/ppc & arch/powerpc).

8ce0a7df6e [POWERPC] 85xx: Don't write reserved values to MAS1[TSIZE]
Some of the current tlbwe instructions early on in head_fsl_booke.S take
advantage of unarchitected behavior that allows the writing of reserved
values to the TSIZE field.  This patch corrects that, as well as an error
where an uninitialized (by linux) value was written into a MAS register and
used for a tlbwe.

Correct this for both arch/ppc and arch/powerpc.

2ef9481e66 [PATCH] powerpc: trivial: modify comments to refer to new location of files
This patch removes all self references and fixes references to files
in the now defunct arch/ppc64 tree.  I think this accomplises
everything wanted, though there might be a few references I missed.

a7cb03375d [PATCH] powerpc/ppc: Add missing isyncs in head_fsl_booke.S
The e500 core reference manual indicates that isync is required
after mtmsr(DE bit) and mtspr DBCR0.  Add isyncs to make the code
conform to the spec.

dc1c1ca3dc powerpc: merge idle_power4.S and trapc.s
Use idle_power4.S from ppc64 as we are not going to support
32 bit power4 in the merged tree.

Merge ppc64 traps.c into powerpc traps.c:
	use ppc64 versions of exception routine names
		(as they don't have StudlyCaps)
	make all the versions if die() have the same
		prototype

14cf11af6c powerpc: Merge enough to start building in arch/powerpc.
This creates the directory structure under arch/powerpc and a bunch
of Kconfig files.  It does a first-cut merge of arch/powerpc/mm,
arch/powerpc/lib and arch/powerpc/platforms/powermac.  This is enough
to build a 32-bit powermac kernel with ARCH=powerpc.

For now we are getting some unmerged files from arch/ppc/kernel and
arch/ppc/syslib, or arch/ppc64/kernel.  This makes some minor changes
to files in those directories and files outside arch/powerpc.

The boot directory is still not merged.  That's going to be interesting.
