7ce04d0ad9 Allocate memory pages for the guest from the host's free page queue. 
It is no longer necessary to hard-partition the memory between the host
and guests at boot time.

bda273f21e Get rid of assumptions in the hypervisor that the host physical memory 
associated with guest physical memory is contiguous.

Rewrite vm_gpa2hpa() to get the GPA to HPA mapping by querying the nested
page tables.

98ed632c63 Stash the 'vm_exit' information in each 'struct vcpu'. 
There is no functional change at this time but this paves the way for vm exit
handler functions to easily modify the exit reason going forward.
