[PATCH v2 0/5] Various IOMMU related simplifications

["Teddy Astie" <teddy.astie@vates.tech>]

Various simplifications in the VT-d and IO-APIC code (mostly related to legacy ia64 code).

No functional change intended.

Changed in v2 :
 - drop (un)map_vtd_domain_page wrapper instead of moving it
 - drop deprecated and Intel-exclusive iommu_inclusive_mapping=<boolean>
 - description and formatting changes

Teddy Astie (5):
  vtd: Drop (un)map_vtd_domain_page wrapper
  vtd: Drop "iommu_inclusive_mapping" command-line option
  vtd: Collapse x86 subdirectory
  vtd: Remove IO_xAPIC_route_entry macro
  x86/ioapic: Don't open-code 32-bits rte reads
