Redundant (but no harm done).
I added it so it's explicit this code is run with IF=0. Kind of
serves a documentation purpose so we don't have to look up
whether the cpu starts with IF=0 or not.

This patch adds a ballooning infrastructure to QEMU. This includes a pair of
monitor commands, balloon and info balloon, to balloon a guest and to query
the guest's balloon status.

This patch adds the virtio balloon driver. It doesn't actually reduce the RSS
size when using KVM (although it does when using -no-kvm). This is because
even with MMU notifiers, we're holding a reference to each page in the shadow
page table. Once we switch to not taking a reference for pages in
This patch updates the virtio device methods to provide hooks for setting and
getting the config. This is needed for ballooning since the balloon driver
uses config changes to signal changes in the balloon amount. We also add a
method to signal that we have changed the config.

This patch adds a kvm_has_mmu_notifiers routine to libkvm. This allows
userspace to query the existence of mmu notifiers which is important for
ballooning since madvise() is not safe from userspace without it.
