Unify the restart callbacks for ISA, AHCI and BMDMA 2. Ensure we can restart a command after migration Many of the early patches only make much sense considering the end-goal of eliminating BMDMA specific restart code to be shared with ISA and AHCI codepaths. Migration for halted commands is fixed for ISA, PCI and AHCI. As a consequence, operations halted via rerror=stop or werror=stop should be able to be successfully migrated and resumed when using ISA, PCI, or AHCI. This series includes tests for ISA and PCI/BMDMA, but does not yet include tests for AHCI, which require some more qtest work to be upstreamed first. Regardless, the AHCI tests have been written and can be observed at: https://github.com/jnsnow/qemu/commits/ahci-devel-latest See "ahci: add migrate dma test" and "ahci-test: add flush migrate test" for the WIP versions of the AHCI test that I used to exercise this patchset.
