[PATCH v3 0/2] x86/pci: reduce PCI accesses

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

First patch is not really related, but it's some cleanup I've found
while looking at the other fixes.  Patch 2 extends the IOMMU logic to
prevent re-writing the same MSI message.

Thanks, Roger.

  x86/apic: remove delivery and destination mode fields from drivers
  x86/iommu: avoid MSI address and data writes if IRT index hasn't
    changed
