2.6.22 came with anon_inode_getfd, but it didn't export it. Since 2.6.23
it is usable for modules, too.

Add an 'info kvm' command to the monitor to be used to determine if KVM is
active. It's very similar to the existing 'info kqemu' command.

When an event (such as an interrupt) is injected, and the stack is
shadowed (and therefore write protected), the guest will exit. The
current code will see that the stack is shadowed and emulate a few
instructions, each time postponing the injection.
