[PATCH 0/2] kvm: disable virtualization on kdump

The following two patches should make kdump work when the kvm-intel module
is loaded. We need to disable vmx mode before booting the kdump kernel,
so I've introduced a notifier interface where KVM can hook and disable
virtualization on all CPUs just before they are halted.

It has the same purpose of the KVM reboot notifier that gets executed
at kexec-time. But on the kdump case, things are not as simple because
the kernel has just crashed.

The notifier interface being introduced is x86-specific. I don't know
if an arch-independent interface would be more appropriate for this

It was tested only using kvm-intel. Testing on different machines
is welcome.
