[Qemu-devel] RFC: Implement emulation of pSeries logical partitions (v2)

[qemu]

This patch series adds a "pseries" machine to qemu, allowing it to
emulate IBM pSeries logical partitions.  Along the way we add a bunch
of support for more modern ppc CPUs than are currently supported.  It
also makes some significant cleanups to the translation code for hash
page table based ppc MMUs.

Changes since v1 of this series:
 * numerous coding style fixups
 * incorporated most review comments from initial version
 * moved to a wholly dynamic hypercall registration scheme
 * assorted other cleanups
 * many more patches implementing VIO devices and basic partition firmware
