- Simplification and distangling of the MSI related functionality
- Let IO/APIC construct the RTE entries from an MSI message instead of
having IO/APIC specific code in the interrupt remapping drivers
- Make the retrieval of the parent interrupt domain (vector or remap
unit) less hardcoded and use the relevant irqdomain callbacks for
selection.
- Allow the handling of more than 255 CPUs without a virtualized IOMMU
when the hypervisor supports it. This has made been possible by the
above modifications and also simplifies the existing workaround in the
HyperV specific virtual IOMMU.
- Cleanup of the historical timer_works() irq flags related
inconsistencies.

Pull x86 apic updates from Thomas Gleixner:
"Yet another large set of x86 interrupt management updates:
- Simplification and distangling of the MSI related functionality
- Let IO/APIC construct the RTE entries from an MSI message instead
of having IO/APIC specific code in the interrupt remapping drivers

unit) less hardcoded and use the relevant irqdomain callbacks for
