From: Sam Ravnborg Date: Mon, 8 Dec 2008 09:04:59 +0000 (-0800) Subject: sparc: fix sparse warnings in traps_32.c X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=8d74e32a537e8dbb22a1d5e9005d11111dab979a;p=linux-beck.git sparc: fix sparse warnings in traps_32.c o add decalrations to entry.h for functions only used from assembler o add declaratiosn to kernel.h for functions only used from .c o removed unused functions/extern declarations Signed-off-by: Sam Ravnborg Signed-off-by: David S.
