Merge tag 'x86_apic_for_6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull x86 apic updates from Dave Hansen:
"This includes a very thorough rework of the 'struct apic' handlers.
Quite a variety of them popped up over the years, especially in the
32-bit days when odd apics were much more in vogue.

The end result speaks for itself, which is a removal of a ton of code
and static calls to replace indirect calls.

If there's any breakage here, it's likely to be around the 32-bit
museum pieces that get light to no testing these days.

Summary:

- Rework apic callbacks, getting rid of unnecessary ones and
coalescing lots of silly duplicates.

- Use static_calls() instead of indirect calls for apic->foo()

- Tons of cleanups an crap removal along the way"

x86/irq: Add hardcoded hypervisor interrupts to /proc/stat

Some hypervisor interrupts (such as for Hyper-V VMbus and Hyper-V timers)
have hardcoded interrupt vectors on x86 and don't have Linux IRQs

x86/irq: Add hardcoded hypervisor interrupts to /proc/stat

Some hypervisor interrupts (such as for Hyper-V VMbus and Hyper-V timers)
have hardcoded interrupt vectors on x86 and don't have Linux IRQs assigned.
These interrupts are shown in /proc/interrupts, but are not reported in
the first field of the "intr" line in /proc/stat because the x86 version
of arch_irq_stat_cpu() doesn't include them.

Fix this by adding code to arch_irq_stat_cpu() to include these interrupts,
similar to existing interrupts that don't have Linux IRQs.

Use #if IS_ENABLED() because unlike all the other nearby #ifdefs,
CONFIG_HYPERV can be built as a module.
