[Qemu-devel] [PATCH 0/4] target-ppc: migration fixups (TCG related)

[Mark Cave-Ayland]

This patchset came out of my work to fix migration for Mac machines under
QEMU running TCG.

Patch 1 was posted to the list a few months ago, but is now part this larger
patchset instead.

Patches 2 and 3 were discovered through a combination of dumping out CPU
structures pre- and post- migration and general code review.

Patch 4 solves the problem that caused random errors when migrating Darwin
images, but seems to duplicate some work that has already been started for
migrating timebase information (see vmstate_ppc_timebase).

I don't have access to any KVM PPC hardware so this has all been tested running
TCG and constantly running savevm/loadvm cycles during a complete Darwin
installation, which in combination with a subsequent macio/DBDMA patchset is
enough to produce a working, bootable image.
