When running with KVM enabled, you can choose between emulating the

of the interrupt controller, it will default to that. If not, if will
default to user space emulation.
Unfortunately when running in user mode gic emulation, we miss out on
timer events which are only available from kernel space. This patch leverages
the new kernel/user space pending line synchronization for those timer events.

Hi everyone,
I probably missed a refresh of this patch, but as I didn't see anything,
I picked this one up today in order to test the KVM support recently
merged. Tweaking this patch a bit to fit the new ABI allowed me to
instantiate a KVM guest without the in-kernel irqchip (tested on a
mustang). So, FWIW, this is report of a successful test. Is there a
refreshed version of this patch someone can point me to, which I should
test instead?
