b8f38eb8d3 Fix two bugs around monitor/mwait
MONITOR relies on tickle_read_virtual to set the physical address, but it was
only doing so on TLB miss. So a MONITOR with a TLB hit would arm the most
recently accessed address instead of the requested one.

TLB invalidations disarmed the monitoring range, but didn't wake a CPU that
had already MWAIT-ed. Any instruction that invalidated TLB entries on other
CPUs could have caused an MWAIT-ing CPU to never wake.

3e333a0d79 Removed APIC timer handles from save/restore list. They are set by the
constructor and should not be modified. Timer activation after restore is not
necessary.
