From b1d1776139698d7522dfd46aa81a056f030ddaf7 Mon Sep 17 00:00:00 2001 From: Baoquan He Date: Tue, 4 Apr 2017 17:02:43 +0100 Subject: [PATCH] x86/efi: Clean up a minor mistake in comment EFI allocates runtime services regions from EFI_VA_START, -4G, down to -68G, EFI_VA_END - 64G altogether, top-down. The mechanism was introduced in commit: d2f7cbe7b26a7 ("x86/efi: Runtime services virtual mapping") Fix the comment that still says bottom-up.
