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

From: Will Deacon <hidden>
Date: 2018-06-01 16:06:01
Also in: lkml

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.

Thanks,

Will
