SubjectRe: [PATCH 02/19] [RFC] x86, apic: Mask IO-APIC and PIC unconditionally on LAPIC resume

So your point is that it works with irq-remapping so it should work without as
well.
The lapic code registers its opcodes as the first syscore device so this code
is always executed before the lapic's and pic resume code. PIC masks its sources
during init so it does not matter if they are masked earlier. And ioapic, well
it restores its entries as well.
So yes, I think this safe to do here.
