Subject: [PATCH v2 0/3] Support rseq on arm64

Hello,

This is version two of the patches previously posted here:

http://lkml.kernel.org/r/1529949285-11013-1-git-send-email-will.deacon@arm.com

Changes since v1 include:

  * Move abort handler in-line to avoid possibility of it being
    out-of-range for conditional branch instructions

I've tested both native and compat (little-endian only) with the selftests
and they pass successfully on my Seattle box.

Thanks,

Will
