The patch adds support for THP (transparent huge pages) to LPAE systems. When this feature is enabled, the kernel tries to map anonymous pages as 2MB sections where possible. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> [steve.capper@linaro.org: symbolic constants used, value of PMD_SECT_SPLITTING adjusted, tlbflush.h included in pgtable.h, added PROT_NONE support.] Signed-off-by: Steve Capper <steve.capper@linaro.org> Reviewed-by: Will Deacon <will.deacon@arm.com>
