Merge tag 'x86-apic-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

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

   - 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"
