[Xen-devel] [PATCH 0/6] x86/vtd: Removal of unnecessary abstractions

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

Patch 1 of this series was XSA-283 before people pointed out that I'd got my
maths wrong.  The rest of the series was the work I was doing at the time, to
try and clean up the IOMMU code.

This series comes with a net bloat-o-meter reduction of -536, a reduction in
code volume, runtime memory usage, and has no practical change in behaviour.

Andrew Cooper (6):
  x86/vtd: Don't include control register state in the table pointers
  x86/vtd: Rename struct iommu to vtd_iommu
  x86/vtd: Drop struct qi_ctrl
  x86/vtd: Drop struct ir_ctrl
  x86/vtd: Drop struct iommu_flush
  x86/vtd: Drop struct intel_iommu
