Hi all,

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")

This build has CONFIG_PPC_MM_SLICES not set ...

I have applied the following patch for today:

From: Stephen Rothwell <redacted>
Date: Thu, 7 Jan 2016 19:07:18 +1100
Subject: [PATCH] powerpc: restore the user_psize member of the mm_context_t in
 the paca

It is used when CONFIG_PPC_MM_SLICES is not set.

Fixes: 2fc251a8dda5 ("powerpc: Copy only required pieces of the mm_context_t to the paca")
Signed-off-by: Stephen Rothwell <redacted>

Applied to powerpc next, thanks.
