From 9679be103108926cfe9e6fd2f6829cefa77e47b0 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 20 Oct 2014 16:41:38 +0200 Subject: arm64/efi: remove idmap manipulations from UEFI code Now that we have moved the call to SetVirtualAddressMap() to the stub, UEFI has no use for the ID map, so we can drop the code that installs ID mappings for UEFI memory regions.
