[Qemu-devel] [PATCHv2 0/7] ppc: loadvm/savevm fixups for -M g3beige and -M mac99

[Mark Cave-Ayland]

This patchset fixes up various bugs in loadvm/savevm for -M g3beige and
-M mac99 so that it is becomes possible to save and restore image snapshots.

The focus of this patchset is on -M g3beige since this matches the majority
of my test images, but there were some easy fixes to be made to -M mac99
at the same time.

With this patchset applied both -M g3beige and -M mac99 images can be
saved/restored whilst booted into OpenBIOS with no issues. I tested -M g3beige
with a paused, disk-inactive Darwin 6 image and was able to resume
successfully which was good enough for my needs.

I noticed some hangs can still occur when trying to restore an image
where the disk is active which makes me believe that there is still some
extra macio/dbdma state which needs to be included if someone is interested
enough to pursue this further.

Most of the patches are straightforward except for patch 4 which came out of
a discussion on-list between Alex and Paolo, and patch 5 which is a similar
error except this time for the MSR register. I suspect patch 5 can be
improved by someone with more PPC knowledge than myself.
