The one failure turns out to be an intermittent failure that has nothing to do with the patch and probably nothing to do with qemu at all. So I heartily approve of these patches.
Thanks very much, Paolo, for taking the time to implement these fixes.

I've been testing these against our entire kernel regression suite. While they definitely fix the original problems, there is one test that now hangs. I'm going to have to get to the bottom of that failure before I can sign off.

Subject: [PATCH 0/3] apic: ExtINT fixes for QNX
Richard Bilson reported some QNX emulation bugs. I sent him offlist a prototype patch, that he commented on.
The first patch here works around what is arguably a QNX bug, that is
triggered by the last two patches; but it is better to avoid spurious
HLT wakeups, so here it is. The last two patches are what Richard
had tested, amended with a fix for Windows XP + KVM + QEMU apic.
Richard, can you confirm that these patches work?
Paolo
Paolo Bonzini (3):
apic: avoid getting out of halted state on masked PIC interrupts
apic: fix loss of IPI due to masked ExtINT
apic: fix incorrect handling of ExtINT interrupts wrt processor
