Since Nate reported a reasonable performance boost from the out-of-line
MSI polling in v1 [1], I've now implemented the equivalent for cons
polling as well - that has been boot-tested on D05 with some trivial I/O
and at least doesn't seem to lock up or explode. There's also a little
cosmetic tweaking to make the patches a bit cleaner as a series.

  iommu/arm-smmu-v3: Specialise CMD_SYNC handling
  iommu/arm-smmu-v3: Forget about cmdq-sync interrupt
  iommu/arm-smmu-v3: Use CMD_SYNC completion interrupt
  iommu/arm-smmu-v3: Poll for CMD_SYNC outside cmdq lock
  iommu/arm-smmu-v3: Use burst-polling for sync completion

What's this final mythical patch about? I don't see it in the series.

Anyway, the first two patches look fine to me, but this doesn't apply
on top of my iommu/devel branch so they will need rebasing.

No idea what I was doing wrong on Friday, but the first two patches apply
cleanly now, so I'll push them out in a bit.

Sorry for the noise,

Will
