powerpc/mm: Split the various pgtable-* headers based on MMU type

2009-03-20T04:56:57Z

This patch moves the definition of the PTE format for each MMU type to separate files instead of all in one file. This improves overall maintainability and will make it easier to add new types. On 64-bit, additionally, I've separated the headers relative to the format of the page table tree (3 vs. 4 levels for 64K vs 4K pages) from the headers specific to the PTE format for hash based processors, this will make it easier to add support for Book3 "E" 64-bit implementations. There are still some type-related ifdef's in the generic headers, we might remove them in the long run, but this patch shouldn't result in any code change, -hopefully- just definitions being moved around.

powerpc: Move include files to arch/powerpc/include/asm

2008-08-04T02:02:00Z

from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell Signed-off-by: Paul Mackerras
