[0/4] AMD/IOMMU: Cleanup

Message

Andrew Cooper Feb. 3, 2020, 2:43 p.m. UTC

Various bits of cleanup without any major functional change.  The eventual
plan is to purge the {get,set}_field_{from,in}_u32() helpers, which are
responsible for very hard to follow code, and poor code generation.

Andrew Cooper (4):
  AMD/IOMMU: Move headers to be local
  AMD/IOMMU: Delete iommu_{get,set,clear}_bit() helpers
  AMD/IOMMU: Treat guest head/tail pointers as byte offsets
  AMD/IOMMU: Treat head/tail pointers as byte offsets
