Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
arch/x86/include/asm/i387.h between commits 8546c008924d ("i387: Uninline
the generic FP helpers that we expose to kernel modules") and
1361b83a13d4 ("i387: Split up <asm/i387.h> into exported and internal
interfaces") from the tip tree and commit
"percpu-remove-percpu_xxx-functions-fix" from the akpm tree.

I applied the appropriate part of the latter patch to
arch/x86/include/asm/fpu-internal.h and arch/x86/kernel/i387.c (see below).
