After merging the powerpc tree, today's linux-next build (powerpc64
allnoconfig) failed like this:

arch/powerpc/mm/hash_utils_64.c: In function 'get_paca_psize':
arch/powerpc/mm/hash_utils_64.c:869:19: error: 'struct paca_struct' has no member named 'context'
  return get_paca()->context.user_psize;
                   ^
arch/powerpc/mm/hash_utils_64.c:870:1: error: control reaches end of non-void function [-Werror=return-type]
 }
 ^

Caused by commit

  2fc251a8dda5 ("powerpc: Copy only required pieces of the mm_context_t to the paca")

Well that's rather embarrassing, for Mikey ;D

This build has CONFIG_PPC_MM_SLICES not set ...

Ugh, but it would seem none of our defconfigs do :/

4K page size with hugetlb disabled will get that 

Yeah, but none of our defconfigs do that.

I've got a kisskb target for it now:
