Subject[PATCH v3 0/5] Switch arm64 over to qrwlock
Date
Hello,

This is version three of the patches previously posted here:

v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-October/534666.html
v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-October/534981.html

Changes since v2 include:

* Drop unused cnt argument
* Fix typo in UNLOCK Kconfig inlining options
* Added Tested-by tags

Thanks to all of those who provided review and testing feedback!
