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).
