[GIT PULL] KVM/ARM updates for v4.1

[Marc Zyngier]

Paolo, Marcelo,

This is the pull request for the KVM/ARM updates targeting v4.1. It
contains a number of important updates bringing the port much closer
to feature completeness.

Note that merging this will generate a small conflict in
virt/kvm/arm/vgic.c, which should be resolved as per linux-next.

Thanks,

	M.
