[Qemu-ppc] [0/4] Assorted ppc/pseries cleanups

[David Gibson]

Andreas,

Here's another batch of pseries patches.  1-3 are cleanups with little
to no functionality change.  4 implements automatic address allocation
for VIO devices, which makes instantiating them with -device rather
easier.

This is about the third small series of patches I have pending for ppc
inclusion.  Would you prefer me to keep sending them this way, or
should I be sending consolidated series with all my pending patches,
even if they've been sent before?
