Subject: linux-next: manual merge of the percpu tree with the tip tree

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
arch/x86/include/asm/percpu.h between commit b1e7734f024c ("x86, percpu:
Use ASM_NOP4 instead of hardcoding P6_NOP4") from the tip tree and commit
5f55924deaa6 ("percpu: Avoid extra NOP in percpu_cmpxchg16b_double") from
the percpu tree.

I fixed it up (see below) and can carry the fix as necessary.

Cheers,
