  "message": "[PATCH] powerpc: Merge cacheflush.h and cache.h\n\nThe ppc32 and ppc64 versions of cacheflush.h were almost identical.\nThe two versions of cache.h are fairly similar, except for a bunch of\nregister definitions in the ppc32 version which probably belong better\nelsewhere.  This patch, therefore, merges both headers.  Notable\npoints:\n\t- there are several functions in cacheflush.h which exist only\non ppc32 or only on ppc64.  These are handled by #ifdef for now, but\nthese should probably be consolidated, along with the actual code\nbehind them later.\n\t- Confusingly, both ppc32 and ppc64 have a\nflush_dcache_range(), but they\u0027re subtly different: it uses dcbf on\nppc32 and dcbst on ppc64, ppc64 has a flush_inval_dcache_range() which\nuses dcbf.  These too should be merged and consolidated later.\n\t- Also flush_dcache_range() was defined in cacheflush.h on\nppc64, and in cache.h on ppc32.  In the merged version it\u0027s in\ncacheflush.h\n\t- On ppc32 flush_icache_range() is a normal function from\nmisc.S.  On ppc64, it was wrapper, testing a feature bit before\ncalling __flush_icache_range() which does the actual flush.  This\npatch takes the ppc64 approach, which amounts to no change on ppc32,\nsince CPU_FTR_COHERENT_ICACHE will never be set there, but does mean\nrenaming flush_icache_range() to __flush_icache_range() in\narch/ppc/kernel/misc.S and arch/powerpc/kernel/misc_32.S\n\t- The PReP register info from asm-ppc/cache.h has moved to\narch/ppc/platforms/prep_setup.c\n\t- The 8xx register info from asm-ppc/cache.h has moved to a\nnew asm-powerpc/reg_8xx.h, included from reg.h\n\t- flush_dcache_all() was defined on ppc32 (only), but was\nnever called (although it was exported).  Thus this patch removes it\nfrom cacheflush.h and from ARCH\u003dpowerpc (misc_32.S) entirely.  It\u0027s\nleft in ARCH\u003dppc for now, with the prototype moved to ppc_ksyms.c.\n\nBuilt for Walnut (ARCH\u003dppc), 32-bit multiplatform (pmac, CHRP and PReP\nARCH\u003dppc, pmac and CHRP ARCH\u003dpowerpc).
