Subject: SUNRPC: Add missing definition of ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=becd2014923ff259b8155df58199f605dd50cb8f;p=linux.git

SUNRPC: Add missing definition of ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE

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.
