The following patch
commit 57ce1659316f4ca298919649f9b1b55862ac3826
KVM: x86: In DM_LOWEST, only deliver interrupts to vcpus with enabled LAPIC's
ignored the fact that kvm_irq_delivery_to_apic() was also used by ia64.
We define kvm_lapic_enabled() to fix a compile error caused by this.
This will have the same effect as reverting the problematic patch for ia64.

Hi,
Isn't this a candidate for 2.6.36?
Though ia64 kvm is in experimental stage and may not be working now, compile
errors may be bad for other people who just want to compile ia64 linux.
Thanks,
Takuya

Maybe we should make ia64 kvm depend on CONFIG_BROKEN.
It has been "experimental" for quite a while.

Ack. We should give people on the IA64 Linux ML a chance to step up on it though. CC'ing them.

I don't think the kvm/ia64 is broken in the upstream Linux, and it should work according to our last try. The big issue is about userspace support. Latest qemu maybe not work with latest kernel, but if you choose an old qemu, it should work!

But without my patch, I failed to (cross-)compile kvm/ia64.
So for a few months, kvm/ia64 was broken in that sense, I guess.
I hope we would have more chance to know in which version kvm/ia64 works!
From my side, I'm sometimes worried whether my patches made something
bad for kvm/ia64, hopefully not of course.
Thanks,
Takuya

When was that?

There's always the chance that changes in the host kernel or
architecture independent kvm code will cause breakage. We need regular
use or testing.
