Linus,

Please git pull the following tag:

 git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip.git for-linus-5.0-rc3-tag

xen: fixes for 5.0-rc3

It contains:
- Several fixes for the Xen pvcalls drivers (1 fix for the backend and
  8 for the frontend).
- A fix for a rather longstanding bug in the Xen sched_clock()
  interface which led to weird time jumps when migrating the system.
- A fix for avoiding accesses to x2apic MSRs in Xen PV guests.


Thanks.

Juergen
