Hi Paul, After merging the rcu tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: fs/binfmt_misc.c: In function 'create_entry': fs/binfmt_misc.c:314:2: error: implicit declaration of function '_copy_from_user' [-Werror=implicit-function-declaration] Caused by commit d17faaa53e2e ("fs: Silence bogus copy_to_user() build errors"). _copy_from_user() appears to only exist for the x86 and tile architectures ... I have used the rcu tree from next-20120413 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx
