[PATCH v4 2/2] arm64 Kconfig: Select gigantic page

2016-09-30 Thread Yisheng Xie
Arm64 supports gigantic page after commit 084bd29810a5 ("ARM64: mm: HugeTLB support.") however, it can only be allocated at boottime and can't be freed. This patch selects ARCH_HAS_GIGANTIC_PAGE to make gigantic pages can be allocated and freed at runtime for arch arm64. Acked-by: Michal Hocko A
