ppc patch queuye for 2017-03-03

Browse Source 
This will probably be my last pull request before the hard freeze.  It
 has some new work, but that has all been posted in draft before the
 soft freeze, so I think it's reasonable to include in qemu-2.9.
 
 This batch has:
     * A substantial amount of POWER9 work
         * Implements the legacy (hash) MMU for POWER9
 	* Some more preliminaries for implementing the POWER9 radix
           MMU
 	* POWER9 has_work
 	* Basic POWER9 compatibility mode handling
 	* Removal of some premature tests
     * Some cleanups and fixes to the existing MMU code to make the
       POWER9 work simpler
     * A bugfix for TCG multiply adds on power
     * Allow pseries guests to access PCIe extended config space
 
 This also includes a code-motion not strictly in ppc code - moving
 getrampagesize() from ppc code to exec.c.  This will make some future
 VFIO improvements easier, Paolo said it was ok to merge via my tree.
