[PATCH-tip v2 0/2] x86/paravirt: Enable users to choose PV lock type

[Waiman Long]

v1->v2:
 - Make pv_spinlock_type a bit mask for easier checking.
 - Add patch 2 to deprecate xen_nopvspin

v1 - https://lkml.org/lkml/2017/11/1/381

Patch 1 adds a new pvlock_type parameter for the administrators to
specify the type of lock to be used in a para-virtualized kernel.

Patch 2 deprecates Xen's xen_nopvspin parameter as it is no longer
needed.

Waiman Long (2):
  x86/paravirt: Add kernel parameter to choose paravirt lock type
  x86/xen: Deprecate xen_nopvspin
