[PATCH 1/6] mm: Generalize ARCH_HAS_CACHE_LINE_SIZE
ARCH_HAS_CACHE_LINE_SIZE config has duplicate definitions on platforms that subscribe it. Instead, just make it a generic option which can be selected on applicable platforms. This change reduces code duplication and makes it cleaner. Cc: Vineet Gupta Cc: Catalin Marinas Cc: Will Deacon Cc: Thomas Gleixner Cc: Ingo Molnar Cc: Borislav Petkov Cc: "H.
