From 1b1fbbcaad56ede1442e7074bd935a2c98b99596 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Sat, 29 Nov 2008 21:44:32 -0800 Subject: sparc,sparc64: prepare vmlinux.lds.S for unification This patch makes the two vmlinux.lds.S files identical and serve as documentation for the changes in each file. This mainly add stuffs to sparc32 that is otherwise only used by sparc64 and thus it should have no effect. Build tested only. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
