Even if that's only a warning, not including asm/cacheflush.h
leads to svc_flush_bvec() being empty allthough powerpc defines
ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE.
CC net/sunrpc/svcsock.o
net/sunrpc/svcsock.c:227:5: warning: "ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE" is not defined [-Wundef]
#if ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE
^
Include linux/highmem.h so that asm/cacheflush.h will be included.
