Various simplifications in the VT-d and IO-APIC code (mostly related to legacy ia64 code).
I think these changes isn't very critical for the current stage of release, so I suggest to
have them in 4.22.
Thanks.

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
