Merge tag 'for-linus-5.0-rc3-tag' of git://git./linux/kernel/git/xen/tip

Pull xen fixes from Juergen Gross:

 - 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.
