From: Eric Dumazet <edumazet@google.com>
rseq is a heavy user of copy to/from user data in fast paths. This series tries to reduce the cost.
v3: Third patch going back to v1 (only deal with 64bit arches) v2: Addressed Peter and Mathieu feedbacks, thanks !
Eric Dumazet (3): rseq: optimize rseq_update_cpu_id() rseq: remove redundant access_ok() rseq: optimise rseq_get_rseq_cs() and clear_rseq_cs()
