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" * tag 'x86-apic-2020-12-14' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (42 commits) x86/ioapic: Cleanup the timer_works() irqflags mess iommu/hyper-v: Remove I/O-APIC ID check from hyperv_irq_remapping_select() iommu/amd: Fix IOMMU interrupt generation in X2APIC mode iommu/amd: Don't register interrupt remapping irqdomain when IR is disabled iommu/amd: Fix union of bitfields in intcapxt support x86/ioapic: Correct the PCI/ISA trigger type selection x86/ioapic: Use I/O-APIC ID for finding irqdomain, not index x86/hyperv: Enable 15-bit APIC ID if the hypervisor supports it x86/kvm: Enable 15-bit extension when KVM_FEATURE_MSI_EXT_DEST_ID detected iommu/hyper-v: Disable IRQ pseudo-remapping if 15 bit APIC IDs are available x86/apic: Support 15 bits of APIC ID in MSI where available x86/ioapic: Handle Extended Destination ID field in RTE iommu/vt-d: Simplify intel_irq_remapping_select() x86: Kill all traces of irq_remapping_get_irq_domain() x86/ioapic: Use irq_find_matching_fwspec() to find remapping irqdomain x86/hpet: Use irq_find_matching_fwspec() to find remapping irqdomain iommu/hyper-v: Implement select() method on remapping irqdomain iommu/vt-d: Implement select() method on remapping irqdomain iommu/amd: Implement select() method on remapping irqdomain x86/apic: Add select() method on vector irqdomain ...
