Hello,

The most important change is the removal of support of OPAL flags
required for P9 DD1. It provides a good cleanup of some complex
routines.

Thanks,

C.

Changes since v1:

 - dropped the change on the allocation of the pages donated to the
   XIVE IC. Needs a retest on a specific system.
 - Took into account Greg's comments on flag removal.
