linux-next: build failure after merge of the powerpc-mpe tree

Hi all,

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


In file included from arch/powerpc/platforms/powernv/setup.c:36:0:
arch/powerpc/include/asm/opal.h:214:17: error: 'enum OpalMessageType' declared inside parameter list [-Werror]
          struct notifier_block *nb);
                 ^

Caused by commit d7cf83fcaf1b ("powerpc/powernv: Move opal-api.h closer
to the Skiboot version") interacting with commit b921e90260ce
("powerpc/powernv: Add OPAL message notifier unregister function") from
the powerpc tree.

I have added the following merge fix patch:

Michael,  you can pull my next-misc branch and apply this fix to the
merge commit to avoid bisection breakage.

linux-next: build failure after merge of the powerpc-mpe tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 624 bytes --]

Hi all,

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

mm/gup.c: In function 'gup_pte_range':
mm/gup.c:904:3: error: conversion to non-scalar type requested
   pte_t pte = ACCESS_ONCE(*ptep);
   ^
mm/gup.c: In function '__get_user_pages_fast':
mm/gup.c:1194:3: error: conversion to non-scalar type requested
   pgd_t pgd = ACCESS_ONCE(*pgdp);
   ^

Caused by commit 4bcad5b3b3ea ("powerpc: Make STRICT_MM_TYPECHECKS a
config option").

I have reverted that commit for today.

I've dropped it from my tree for now.

You can kill me on Monday.
