sh: Don't export __{s,u}divsi3_i4i from SH-2 libgcc.
rsk7203_defconfig fails to build with the following error: <-- snip --> ... LD .tmp_vmlinux1 arch/sh/kernel/built-in.o:(__ksymtab+0xb8): undefined reference to `__udivsi3_i4i' arch/sh/kernel/built-in.o:(__ksymtab+0xc8): undefined reference to `__sdivsi3_i4i' make[1]: *** [.tmp_vmlinux1] Error 1 <-- snip --> That worked with 2.6.26, and these are far less undefined references than in the cases where libgcc was missing. [ These symbols are not defined on SH-2 versions of libgcc, so we have to special case the export there. - Paul ] Reported-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Yoshinori Sato <ysato@users.sourceforge.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
