Patch 1 simplifies the pvclock.h API by moving seqcount logic into
two new functions pvclock_read_begin and pvclock_read_retry.
Patch 2 uses the new simplified API in the vDSO.

Please ack the vDSO changes!

Paolo

v2->v3: add unlikely() around read_retry check.

Paolo Bonzini (2):
  pvclock: introduce seqcount-like API
  x86: vdso: use __pvclock_read_cycles
