[PATCH 0/3] rseq: minor optimizations

[Eric Dumazet]

From: Eric Dumazet <edumazet@xxxxxxxxxx>

rseq is a heavy user of copy to/from user data in fast paths.
This series tries to reduce the cost.

Eric Dumazet (3):
  rseq: optimize rseq_update_cpu_id()
  rseq: remove redundant access_ok()
  rseq: optimise for 64bit arches
