Linus Torvalds 148842c98a 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.
