mm: generalize ARCH_HAS_CACHE_LINE_SIZE
Patch series "mm: some config cleanups", v2.
This series contains config cleanup patches which reduces code
duplication across platforms and also improves maintainability. There
is no functional change intended with this series.
This patch (of 6):
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.
