[Qemu-devel] [PATCH 0/4] ppc: loadvm/savevm fixups for macio/DBDMA

[Mark Cave-Ayland]

This patchset fixes up macio/DBDMA to allow migration to succeed for Mac
machines while IDE/DMA requests are in-flight, and in conjunction with the
migration fixup patchset, enables me to successfully migrate live VMs
under TCG.

Migration was tested by running through a complete Darwin install whilst
issuing savevm/loadvm command pairs every minute or so in the monitor
with no visible ill-effects, and resulted in a bootable disk image.

  macio: use the existing IDEDMA aiocb to hold the active DMA aiocb
