Fix that the blocking by SMI bit maybe set when a VM-exit ends outside SMM ( #15 )
...
* Fix that the blocking by SMI bit is set
The blocking by SMI bit of the guest interruptibility state VMCS should
not be set unless the VM-exit ends in SMM. This only happens under the
dual-monitor treatment, which is not implemented in Bochs.
* Remove trailing whitespaces

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.
