Flushes were truncated at 4GB, so larger flushes were incorrect. 2. Flushing the dcache in arch_add_memory was unnecessary This series also converts much of the cache assembler to C, with the aim of making it easier to maintain. Alastair D'Silva (6): powerpc: Allow flush_icache_range to work across ranges >4GB powerpc: define helpers to get L1 icache sizes powerpc: Convert flush_icache_range & friends to C powerpc: Chunk calls to flush_dcache_range in arch_*_memory powerpc: Remove 'extern' from func prototypes in cache headers powerpc: Don't flush caches when adding memory arch/powerpc/include/asm/cache.h | 63 +++++++++----- arch/powerpc/include/asm/cacheflush.h | 49 ++++++----- arch/powerpc/kernel/misc_32.S | 117 -------------------------- arch/powerpc/kernel/misc_64.S | 97 --------------------- arch/powerpc/mm/mem.c | 80 +++++++++++++++++- 5 files changed, 146 insertions(+), 260 deletions(-) -- 2.21.0
