2008-06-10powerpc: Remove arch/ppc and include/asm-ppcPaul Mackerras
All the maintained platforms are now in arch/powerpc, so the old arch/ppc stuff can now go away.

2006-02-10[PATCH] powerpc: trivial: modify comments to refer to new location of filesJon Mason
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. Signed-off-by: Jon Mason <jdmason@us.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
2006-01-09[PATCH] ppc32: Put cache flush routines back into .relocate_code sectionPaul Janzen
In 2.6.14, we had the following definition of _GLOBAL() in include/asm-ppc/processor.h: #define _GLOBAL(n)\ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n;\ n: In 2.6.15, as part of the great powerpc merge, we moved this definition to include/asm-powerpc/ppc_asm.h, where it appears (to 32-bit code) as: #define _GLOBAL(n) \ .text; \ .stabs __stringify(n:F-1),N_FUN,0,0,n;\ .globl n; \ n: Mostly, this is fine. However, we also have the following, in arch/ppc/boot/common/util.S: .section ".relocate_code","xa" [...] _GLOBAL(flush_instruction_cache) [...] _GLOBAL(flush_data_cache) [...] The addition of the .text section definition in the definition of _GLOBAL overrides the .relocate_code section definition. As a result, these two functions don't end up in .relocate_code, so they don't get relocated correctly, and the boot fails. There's another suspicious-looking usage at kernel/swsusp.S:37 that someone should look into. I did not exhaustively search the source tree, though. The following is the minimal patch that fixes the immediate problem. I could easily be convinced that the _GLOBAL definition should be modified to remove the ".text;" line either instead of, or in addition to, this fix.

2005-09-09[PATCH] ppc32: Correct an instruction in the boot codeFrank van Maarseveen
In the flush and invalidate bootcode on PPC4xx we were accidentally using the wrong instruction. Use cmplw, which reads from a register like we want. Signed-off-by: Tom Rini <trini@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
