We have __weak in
gcc seems to define __builtin_clz as __clzsi2 in some architecture.
But, kernel doesn't link libgcc.a.
If kernel should use gcc's built-in function without libgcc.a,
do we need to port __clzsi2 to 'arch/*/lib/*'?
This breaks alpha (gcc-4.4.4) as well. Can we please get this fixed
promptly?

It seems at least m68k and sparc don't have

This patch adds support for LZ4 compression in the Linux Kernel.
LZ4 Compression APIs for kernel are based on LZ4 implementation
by Yann Collet and changed with kernel coding style.
