Subject: [RESEND PATCH v2 0/9] Rewrite asm-generic/bitops/{atomic,lock}.h and use on arm64

Hi all,

This is a resend of the patches I previously sent 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
     v2: https://lkml.org/lkml/2018/6/1/619

The only change is that I have rebased onto v4.18-rc1.

Ingo -- please can you queue this via -tip when you start picking up
patches for 4.19? It doesn't conflict with Mark's atomic API rework.

Thanks,

Will
