[PATCH 0/3] KVM: x86: Clean up lowest priority IRQ code

Posted by Sean Christopherson 1 month, 1 week ago

Move some local APIC specific code into lapic.c that has no business being
exposed outside of local APIC emulation.   The lowest priority vector
hashing code in particular is *very* specific to lapic.c internals, but
that's not at all obvious from the globally-visible symbols.
