Subject: [PATCH] include/linux/kernel.h: Remove labs()

Remove labs() since it is not used/needed.

Signed-off-by: Richard Knutsson <ricknu-0@...dent.ltu.se>

Could not find any references to it (other then defined in gcc's stdlib.h),
compile-tested with "allyes" on i386 just to be sure.
If abs()'s int is not sufficient, it then should be replaced with typeof (imho).
