[PATCH] i386: vMI timer patches
VMI timer code. It works by taking over the local APIC clock when APIC is
configured, which requires a couple hooks into the APIC code. The backend
timer code could be commonized into the timer infrastructure, but there are
some pieces missing (stolen time, in particular), and the exact semantics of
when to do accounting for NO_IDLE need to be shared between different
hypervisors as well. So for now, VMI timer is a separate module.
