Guo Ren 4ad35c1f56 csky: Fixup 610 vipt cache flush mechanism ... 610 has vipt aliasing issue, so we need to finish the cache flush apis mentioned in cachetlb.rst to avoid data corruption. Here is the list of modified apis in the patch: - flush_kernel_dcache_page (new add) - flush_dcache_mmap_lock (new add) - flush_dcache_mmap_unlock (new add) - flush_kernel_vmap_range (new add) - invalidate_kernel_vmap_range (new add) - flush_anon_page (new add) - flush_cache_range (new add) - flush_cache_vmap (flush all) - flush_cache_vunmap (flush all) - flush_cache_mm (only dcache flush) - flush_icache_page (just nop) - copy_from_user_page (remove no need flush) - copy_to_user_page (remove no need flush) Change to V2: - Fixup compile error with xa_lock*(&mapping->i_pages) Signed-off-by: Guo Ren <ren_guo@c-sky.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Christoph Hellwig <hch@infradead.org>		2019-08-22 10:44:24 +08:00
