I think -tip would make the most sense, if that's ok with Ingo. Cheers, Will
Hi all, This patch series has previously been posted in RFC form here: RFCv1: https://www.spinics.net/lists/arm-kernel/msg634719.html RFCv2: https://www.spinics.net/lists/arm-kernel/msg636875.html v1: https://www.spinics.net/lists/arm-kernel/msg655262.html The only change since v1 is that some of the fetch ops are replaced by non-value-returning ops for some of the atomic bitops.
