2014-04-03	lib/clz_ctz.c: add prototype declarations in lib/clz_ctz.c	Rashika Kheria	1	-0/+7
	Add prototype declarations of functions in lib/clz_ctz.c. These functions are required by GCC builtins and hence can not be removed despite of their unreferenced appearance in kernel source. This eliminates the following warning in lib/clz_ctz.c: lib/clz_ctz.c:16:12: warning: no previous prototype for `__ctzsi2' [-Wmissing-prototypes] lib/clz_ctz.c:22:12: warning: no previous prototype for `__clzsi2' [-Wmissing-prototypes] lib/clz_ctz.c:44:12: warning: no previous prototype for `__clzdi2' [-Wmissing-prototypes] lib/clz_ctz.c:50:12: warning: no previous prototype for `__ctzdi2' [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@gmail.com> Reviewed-by: Josh Triplett <josh@joshtriplett.org> Acked-by: Chanho Min <chanho.min@lge.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2013-07-09	lib: add weak clz/ctz functions	Chanho Min	1	-0/+58
	Some architectures need __c[lt]z[sd]i2() for __builtin_c[lt]z[ll] and that causes a build failure. They can be implemented using the fls()/__ffs() and overridden by linking arch-specific versions may not be implemented yet. This is required by "lib: add lz4 compressor module".
