Merge tag 'x86-irq-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 irq updates from Thomas Gleixner: "Surgery of the MSI interrupt handling to prepare the support of upcoming devices which require non-PCI based MSI handling: - Cleanup historical leftovers all over the place - Rework the code to utilize more core functionality - Wrap XEN PCI/MSI interrupts into an irqdomain to make irqdomain assignment to PCI devices possible. - Assign irqdomains to PCI devices at initialization time which allows to utilize the full functionality of hierarchical irqdomains. - Remove arch_.*_msi_irq() functions from X86 and utilize the irqdomain which is assigned to the device for interrupt management. - Make the arch_.*_msi_irq() support conditional on a config switch and let the last few users select it" * tag 'x86-irq-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) PCI: MSI: Fix Kconfig dependencies for PCI_MSI_ARCH_FALLBACKS x86/apic/msi: Unbreak DMAR and HPET MSI iommu/amd: Remove domain search for PCI/MSI iommu/vt-d: Remove domain search for PCI/MSI[X] x86/irq: Make most MSI ops XEN private x86/irq: Cleanup the arch_*_msi_irqs() leftovers PCI/MSI: Make arch_.*_msi_irq[s] fallbacks selectable x86/pci: Set default irq domain in pcibios_add_device() iommm/amd: Store irq domain in struct device iommm/vt-d: Store irq domain in struct device x86/xen: Wrap XEN MSI management into irqdomain irqdomain/msi: Allow to override msi_domain_alloc/free_irqs() x86/xen: Consolidate XEN-MSI init x86/xen: Rework MSI teardown x86/xen: Make xen_msi_init() static and rename it to xen_hvm_msi_init() PCI/MSI: Provide pci_dev_has_special_msi_domain() helper PCI_vmd_Mark_VMD_irqdomain_with_DOMAIN_BUS_VMD_MSI irqdomain/msi: Provide DOMAIN_BUS_VMD_MSI x86/irq: Initialize PCI/MSI domain at PCI init time x86/pci: Reducde #ifdeffery in PCI init code ...
