Olof Johansson	3467bfd340	[POWERPC] Use mtocrf instruction in asm when CONFIG_POWER4_ONLY=y ... mtocrf is a faster single-field mtcrf (move to condition register fields) instruction available in POWER4 and later processors. It can make quite a difference in performance on some implementations, so use it for CONFIG_POWER4_ONLY builds.

Jon Mason	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.

Benjamin Herrenschmidt	3c726f8dee	[PATCH] ppc64: support 64k pages ... Adds a new CONFIG_PPC_64K_PAGES which, when enabled, changes the kernel base page size to 64K. The resulting kernel still boots on any hardware. On current machines with 4K pages support only, the kernel will maintain 16 "subpages" for each 64K page transparently. Note that while real 64K capable HW has been tested, the current patch will not enable it yet as such hardware is not released yet, and I'm still verifying with the firmware architects the proper to get the information from the newer hypervisors.

Paul Mackerras	70d64ceaa1	powerpc: Rename files to have consistent _32/_64 suffixes ... This doesn't change any code, just renames things so we consistently have foo_32.c and foo_64.c where we have separate 32- and 64-bit versions.
