From 49759743bf090dfa859f036804630e54b8a3f803 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 18 Nov 2018 17:58:46 +0100 Subject: [PATCH] efi_loader: eliminate sandbox addresses Do not use the sandbox's virtual address space for the internal structures of the memory map. This way we can eliminate a whole lot of unnecessary conversions. The only conversion remaining is the one when adding known memory.
