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

    Changes since RFCv2 include:

    * Rebased onto v4.17-rc4, which allowed me to drop some patches from
    the series which were merged in 4.16.

    * Moved bit.h to be linux/bit.h instead of asm-generic/bit.h

    Thanks,

    Will
