From f026cfa82f628db24b8cea41b9d6202af104cecb Mon Sep 17 00:00:00 2001 From: "H. Peter Anvin" Date: Tue, 14 Aug 2012 09:53:38 -0700 Subject: Revert "x86-64/efi: Use EFI to deal with platform wall clock" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit bacef661acdb634170a8faddbc1cf28e8f8b9eee. This commit has been found to cause serious regressions on a number of ASUS machines at the least. We probably need to provide a 1:1 map in addition to the EFI virtual memory map in order for this to work. Signed-off-by: H.
