it is possible that SPP-protected subpage block is allowing write but all others are not.
the TLB entry cannot be cached as writeOK based on SPP subblock check

Fix that the INIT signal remains pending even after delivery of VM-exit/#VMEXIT(INIT) (#16) 
* Clear pending INIT signal

When the INIT signal is translated into corresponding VM-exit/#VMEXIT,
the signal should no longer be marked as pending. Otherwise, the signal
would be (incorrectly) delivered again.

* Remove trailing space and fix an incorrect indent

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

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.

constructor and should not be modified. Timer activation after restore is not
necessary.
