Load-qwords-into-physical-memory-list

Load lists of physical-addr-qword-alistp into the physical memory.

Signature

(load-qwords-into-physical-memory-list addr-qword-list-list x86) 
  → 
x86

Arguments

addr-qword-list-list — Required to be physical-addr-qword-alist-listp.

Returns

x86 — Type (x86p x86), given the guard.

This function can be used to initialize the page tables.
