During the discussion [1] that took place after
the patch was merged it was agreed that it should
be reverted to avoid introducing a bad interface.

Furthermore, the patch rejected usage of flag
XEN_DOMCTL_CDF_vpci for x86 which is not true
as it should be set for dom0 PVH.

Due to XEN_DOMCTL_CDF_vpmu being introduced after
XEN_DOMCTL_CDF_vpci, modify its bit position
from 8 to 7.

Looking at the thread, we are only missing an ack for...

  tools/ocaml/libs/xc/xenctrl.ml  | 1 - >   tools/ocaml/libs/xc/xenctrl.mli | 1 

the OCAML part. I can commit it once this is done.
