Merge tag 'x86-irq-2021-08-30' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 PIRQ updates from Thomas Gleixner:
"A set of updates to support port 0x22/0x23 based PCI configuration
space which can be found on various ALi chipsets and is also available
on older Intel systems which expose a PIRQ router.
While the Intel support is more or less nostalgia, the ALi chips are
still in use on popular embedded boards used for routers"
