[patch V2 0/3] x86/irq: Bugfix and cleanup for posted MSI interrupts

[Thomas Gleixner]

A small update to V1 which can be found here:

  https://lore.kernel.org/lkml/20251125101912.564125647@xxxxxxxxxxxxx

Luigi reported that the retrigger mechanism for posted MSI interrupts is
broken. That happens because retrigger sends an IPI to the actual allocated
vector, which is handled correctly, but lacks an EOI. That leaves a stale
APIC ISR bit around.

The following series addresses this and does some related cleanups in that
area on top.

Changes vs. V1:

   Use __this_cpu_*() - Luigi

Thanks,
