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
