From b2a39b0d8ec2ce2bdcff4e01572b4e885220254d Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Tue, 4 Jan 2011 11:39:12 +0000 Subject: sparc: use _start for the start entry (like 64 bit does) We use "_start" in 64 bit - do the same in 32 bit. It is always good to be consistent. Signed-off-by: Sam Ravnborg Signed-off-by: David S.
