Hi Boqun,
Can you please split this into two patches. One that does the cmpxchg change
and one that changes PPC_ATOMIC_ENTRY_BARRIER.
Also given how pervasive this change is I'd like to take it via the powerpc
next tree, so can you please send this patch (which will be two after you split
it) as powerpc patches. And the rest can go via tip?
cheers
