Hi,

Please find the rseq enablement patchset for inclusion into glibc.

I took care of the round of feedbacks from last week, and rebased the
series on glibc's master branch.

Thanks!

Mathieu

Mathieu Desnoyers (3):
  glibc: Perform rseq registration at C startup and thread creation
    (v22)
  Linux: Use rseq in sched_getcpu if available (v9)
  rseq registration tests (v11)
