  ppc/pnv: use IEC binary prefixes to represent sizes (2019-02-26 14:20:30 
+1100)

----------------------------------------------------------------
ppc patch queue 2019-02-26

Next set of patches for ppc and spapr.  There's a lot in this one:
 * Support "STOP light" states on POWER9
 * Add support for HVI interrupts on POWER9 (powernv machine)
 * CVE-2019-8934: Don't leak host model and serial information to the guest
 * Tests and cleanups for various hot unplug options
 * Hash and radix MMU implementation on POWER9 for powernv machine
 * PCI Host Bridge hotplug support for pseries machine
 * Allow larger kernels and initrds for powernv machine

Plus a handful of miscellaneous fixes and cleanups.

The cpu hotplug tests and cleanups from David Hildenbrand aren't
solely power related.  However the consensus amongst Michael Tsirkin,
David Hildenbrand, Cornelia Huck and myself was that it made most
sense to come in via my tree.
