Merge tag 'irq-msi-2022-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull MSI irq updates from Thomas Gleixner:
"Rework of the MSI interrupt infrastructure.
This is a treewide cleanup and consolidation of MSI interrupt handling
in preparation for further changes in this area which are necessary
to:
- address existing shortcomings in the VFIO area
- support the upcoming Interrupt Message Store functionality which
decouples the message store from the PCI config/MMIO space"
