The ppc32 and ppc64 versions of cacheflush.h were almost identical. The two versions of cache.h are fairly similar, except for a bunch of register definitions in the ppc32 version which probably belong better elsewhere. This patch, therefore, merges both headers. Notable points: - there are several functions in cacheflush.h which exist only on ppc32 or only on ppc64. These are handled by #ifdef for now, but these should probably be consolidated, along with the actual code behind them later. - Confusingly, both ppc32 and ppc64 have a flush_dcache_range(), but they're subtly different: it uses dcbf on ppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which uses dcbf. These too should be merged and consolidated later. - Also flush_dcache_range() was defined in cacheflush.h on ppc64, and in cache.h on ppc32. In the merged version it's in cacheflush.h - On ppc32 flush_icache_range() is a normal function from misc.S. On ppc64, it was wrapper, testing a feature bit before calling __flush_icache_range() which does the actual flush. This patch takes the ppc64 approach, which amounts to no change on ppc32, since CPU_FTR_COHERENT_ICACHE will never be set there, but does mean renaming flush_icache_range() to __flush_icache_range() in arch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S - The PReP register info from asm-ppc/cache.h has moved to arch/ppc/platforms/prep_setup.c - The 8xx register info from asm-ppc/cache.h has moved to a new asm-powerpc/reg_8xx.h, included from reg.h - flush_dcache_all() was defined on ppc32 (only), but was never called (although it was exported). Thus this patch removes it from cacheflush.h and from ARCH=powerpc (misc_32.S) entirely. It's left in ARCH=ppc for now, with the prototype moved to ppc_ksyms.c.
