ARM64: mm: THP support.
Bring Transparent HugePage support to ARM. The size of a transparent huge page depends on the normal page size. A transparent huge page is always represented as a pmd. If PAGE_SIZE is 4KB, THPs are 2MB. If PAGE_SIZE is 64KB, THPs are 512MB. Signed-off-by: Steve Capper <steve.capper@linaro.org> Acked-by: Catalin Marinas <catalin.marinas@arm.com>
