linux-next: build failure after merge of the final tree (akpm tree related)

Hi Andrew,

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

In file included from include/linux/posix_types.h:47:0,
                 from include/linux/types.h:17,
                 from include/linux/page-flags.h:8,
                 from kernel/bounds.c:9:
arch/powerpc/include/asm/posix_types.h:15:14: error: conflicting types for '__kernel_size_t'
arch/powerpc/include/asm/posix_types.h:14:22: note: previous declaration of '__kernel_size_t' was here
In file included from include/linux/page-flags.h:8:0,
                 from kernel/bounds.c:9:
include/linux/types.h:68:1: error: unknown type name '__kernel_ssize_t'

Caused by commit a9dbe86e5995 ("powerpc: use generic posix_types.h").

This think was pointed out a couple of days ago, so maybe Andrew needs a
newer version of the patch.

I added this fix patch for today:

Yes, I pointed that out to Peter a while back, maybe it got lost ...

Cheers,
Ben.
