Patch series "arch: include asm/cacheflush.h in asm/hugetlb.h". Three architectures are using PG_dcache_clean in their asm/hugetlb.h, but relying on accident to include the asm/cacheflush.h which defines it. This patch (of 3): PG_dcache_clean is used in asm/hugetlb.h but defined in asm/cacheflush.h: builds rely on an accident of that being included via linux/mempolicy.h, but better include it directly (like arch/sh/include/asm/hugetlb.h does).
