powerpc: Trivially merge several headers from asm-ppc64 to asm-powerpc For these, I have just done the lame-o merge where the file ends up looking like: #ifndef CONFIG_PPC64 #include <asm-ppc/foo.h> #else ... contents from asm-ppc64/foo.h #endif so nothing has changed, really, except that we reduce include/asm-ppc64 a bit more.

[PATCH] powerpc: sanitize header files for user space includes include/asm-ppc/ had #ifdef __KERNEL__ in all header files that are not meant for use by user space, include/asm-powerpc does not have this yet. This patch gets us a lot closer there. There are a few cases where I was not sure, so I left them out. I have verified that no CONFIG_* symbols are used outside of __KERNEL__ any more and that there are no obvious compile errors when including any of the headers in user space libraries.

[POWERPC] Start factoring pgtable-ppc32.h and pgtable-ppc64.h This factors some things defined in both pgtable-ppc32.h and pgtable-ppc64.h into the common part of asm-powerpc/pgtable.h. These are all things which have essentially identical definitions, and which by their nature are very unlikely ever to need different definitions in the two cases.

[POWERPC] Remove arch/powerpc's dependence on asm-ppc/pg{alloc,table}.h Currently, all 32-bit powerpc platforms use asm-ppc/pgtable.h and asm-ppc/pgalloc.h, even when otherwise compiled with ARCH=powerpc. Those asm-ppc files are a fairly nasty tangle of #ifdefs including a bunch of things which shouldn't be necessary any more in arch/powerpc. Cleaning up that mess is going to take a while, but this patch is a first step. It separates the asm-powerpc/pg{alloc,table}.h into 64 bit and 32 bit versions in asm-powerpc, which the basic .h files in asm-powerpc select based on config. We make a few tiny tweaks to the innards of the files along the way, making the outermost ifdefs (double-inclusion protection and __KERNEL__) a little cleaner, and #including asm-generic/pgtable.h from the top-level asm-powerpc/pgtable.h (since both the old 32-bit and 64-bit versions ended with such an #include).

[PATCH] Four level pagetables for ppc64 Implement 4-level pagetables for ppc64 This patch implements full four-level page tables for ppc64, thereby extending the usable user address range to 44 bits (16T). The patch uses a full page for the tables at the bottom and top level, and a quarter page for the intermediate levels. It uses full 64-bit pointers at every level, thus also increasing the addressable range of physical memory. This patch also tweaks the VSID allocation to allow matching range for user addresses (this halves the number of available contexts) and adds some #if and BUILD_BUG sanity checks.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
