Log:
Virtual memory works baby! Virtual Heap at 0x80000000 fully enabled. Next up, EFI
Protocols with Paging Enabled.
[BOOTLIB]: Fix dumb bug in BlMmIsTranslationEnabled which would always return FALSE.
[BOOTLIB]: Fix dumber bug in MmDefInitializeTranslation which was freeing the page
directories and self-map pages even in the success path. Causing us to zero out paging
structures...
[BOOTLIB]: Cleanup and extend MmMdDbgDumpList for internal use, and add
MmMdListPointerToName as another debug function.
[BOOTLIB]: Add a few more checkpoints in unimplemented paths.
