Hi all,

After merging the net-next tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

lib/hash.c:16:43: error: expected '=', ',', ';', 'asm' or '__attribute__' before '__read_mostly'
static struct fast_hash_ops arch_hash_ops __read_mostly = {
^
lib/hash.c: In function 'arch_fast_hash':
lib/hash.c:23:9: error: 'arch_hash_ops' undeclared (first use in this function)
return arch_hash_ops.hash(data, len, seed);
^
lib/hash.c:23:9: note: each undeclared identifier is reported only once for each function it appears in
lib/hash.c: In function 'arch_fast_hash2':
lib/hash.c:29:9: error: 'arch_hash_ops' undeclared (first use in this function)
return arch_hash_ops.hash2(data, len, seed);
^
lib/hash.c: In function 'hashlib_init':
lib/hash.c:35:24: error: 'arch_hash_ops' undeclared (first use in this function)
setup_arch_fast_hash(&arch_hash_ops);
^
lib/hash.c: In function 'arch_fast_hash':
lib/hash.c:24:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^
lib/hash.c: In function 'arch_fast_hash2':
lib/hash.c:30:1: warning: control reaches end of non-void function [-Wreturn-type]
}
^

Caused by commit 71ae8aac3e19 ("lib: introduce arch optimized hash
library"). Read Rule 1 in Documentation/SubmitChecklist :-( Hint:
__read_mostly is defined in linux/cache.h ...

I have used the net-next tree from next-20131217 again today.
