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"
