This has been gone over many times, user programs shouldn't be using
kernel headers.  I don't mind if you change /usr/include/asm/atomic.h,
that's a glibc header not a kernel header, but the #ifdef __KERNEL__
in the kernel header is there precisely to catch this sort of error.

(And of course /usr/include/asm should NOT be a symlink into the
kernel sources.)
