[PATCH] xen/kexec: Wire up kexec hypercalls for PVH hardware domains

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Nothing in do_kexec_op() is PV specific.  Plumb in PVH guests too.

kexec-tools in userspace still has a PV check needing dropping before kexec is
generally usable for PVH dom0's, but the Xen side should be all fine.

Bloat-o-meter reports:

  Function                                     old     new   delta
  hvm_hypercall                               2118    2309    +191
  hvm_do_multicall_call                       1366    1411     +45
  Total: Before=4226938, After=4227174, chg +0.01%

which reinforces my hatred of this entire infrastructure.
