From 15f1483404f3497c66872de13f3d585e3da87785 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 11 Dec 2006 21:06:55 -0800 Subject: [PATCH] [SPARC64]: Kill no-remapping-needed code in head.S It branches around some necessary prom calls, which we would need to do even if we are mapped at the correct location already. So it doesn't work. The idea was that this sort of thing could be used for the eventual kexec implementation, but it is clear that this will need to be done differently. Signed-off-by: David S.
