Shall we add here also the last 2 patches from my series that actually enable
the eventfd compilation and KVM_CAP_IOEVENTFD? Or should I send them sepa
cleaner and straightforward than what
it was before.

This is needed in e.g. ARM vGIC emulation, where the MMIO handling
depends on the VCPU that does the access.

The patches are implemented on top of the latest Andre's vGICv3 work from here:
http://www.linux-arm.org/git?p=linux-ap.git;a=shortlog;h=refs/heads/kvm-gicv3/v4
The code was tested on Dual Cortex-A15 Exynos5250 (ARM Chromebook).
