One-to-one GVA to GPA mappings can be used in the guest to set up boot sequences during which paging is enabled, hence requiring a transition from using physical to virtual addresses in consecutive instructions.

NAK, this is an extremely convoluted way for establishing mappings for hardcoded boot ranges. Just use virt_map(). And if clobbering an existing mapping is a concern, we should add an assert in virt_map() to verify the address is available.

I'm able to replace this with virt_map() as you suggested. I'll drop this patch in the next version.
