L4 inaccessible without bootloader provided virtual offset

I have spent pretty close to a week trying to figure this out. In older versions there was the map_physical_memory feature, which appears to have been removed as of v0.10.0. I have tried everything I can think of to no avail. Any time I try to access the L4 table to map the rest of the memory, I get a page daily.

Things I have tried:

• reverse calculating an offset from the logs
• creating a new L4 using 4KiB aligned static mut
• I even tried patching in an offset on my own fork of the repo

I am at a loss for how to set up memory without a valid offset

Start by comparing the v0.10.0 memory-mapping changes with the older map_physical_memory feature, then trace how the L4 table is made available and how its virtual offset is determined. Done means documenting or implementing a supported way to obtain the offset so the remaining memory can be mapped without a page fault.
