[Devel] [PATCH hci-8.1 v5 0/5] timens: Remove dependency on the vDSO

[Eva Kurchatova]

Changes in v3:

- Drop offset_lock extern declaration, so that the picks apply clean.
- Mainline commits are git cherry-pick -x of mainline, with the conflict
  resolution described in a rebase note where the patch differs.
- Drop the freeze fix from the series: Low priority, the same issue
  exists in mainline, and not exploitable. Goes mainline first.
- Drop the sparc config workaround: VZKernel doesn't target sparc, will
  be fixed if ever needed by a newer kernel import.
