Hi Andrew,

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

In file included from /scratch/sfr/next/include/linux/stat.h:60:0,
                 from /scratch/sfr/next/include/linux/module.h:10,
                 from /scratch/sfr/next/init/do_mounts.c:1:
/scratch/sfr/next/include/linux/time.h: In function '__FD_ZERO':
/scratch/sfr/next/include/linux/time.h:279:2: error: implicit declaration of function 'memset' [-Werror=implicit-function-declaration]

... and many similar.

Caused by commit 5607ffd42bae ("posix_types: remove fd_set macros").

I have reverted that commit (and the following checkpatch fix commit) for
today.
