Hi Andrew,

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

arch/powerpc/lib/code-patching.c:61:16: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'is_conditional_branch'
 bool __kprobes is_conditional_branch(unsigned int instr)
                ^

Caused by commit

  916c821aaf13 ("kprobes: move kprobe declarations to asm-generic/kprobes.h")

interacting with commit

  51c9c0843993 ("powerpc/kprobes: Implement Optprobes")

from the powerpc tree.

I have applied this merge fix patch for today:

From: Stephen Rothwell <redacted>
Date: Tue, 14 Feb 2017 16:56:11 +1100
Subject: [PATCH] powerpc/kprobes: fixup for kprobes declarations moving
