[PATCH v5 0/2] x86/xen: add xen hypercall preemption

[Luis R. Rodriguez]

From: "Luis R. Rodriguez" <mcgrof@xxxxxxxx>

This v5 nukes tracing as David said it was useless, it also
only adds support for 64-bit as its the only thing I can test,
and slightly modifies the documentation in code as to why we
want this. The no krobe thing is left in place as I haven't
heard confirmation its kosher to remove it.

Luis R. Rodriguez (2):
  x86/xen: add xen_is_preemptible_hypercall()
  x86/xen: allow privcmd hypercalls to be preempted on 64-bit
