Merge remote-tracking branch 'mst/tags/for_anthony' into staging
pci, pc, virtio bug fixes
This reverts PCI master abort support - we'll want it
eventually but it exposes too many core bugs to be safe for 1.7.
This also reverts a recent exec.c change that was an
attempt to work-around some of these core bugs.
Also included are small fixes in pc and virtio,
and a core loader fix for PPC bamboo.
