Log message:
vmm(4): add IOCTL handler to sets the access protections of the ept
This exposes VMM_IOC_MPROTECT_EPT which can be used by vmd to lock in physical
pages. Currently, vmd just terminates the vm in case it gets a protection fault
in the future.
This feature is used by solo5 which uses vmm(4) as a backend hypervisor.
