[PATCH] remove #ifdef __KERNEL__ from atomic.h

Hi,

I was trying to compile sumji (formerly xtunes), which requires
libCommonC++. I found that libCommonC++ would not compile, because it
needs to use the atomic functions declared in include/asm-ppc/atomic.h .
However, this file does not declare these functions unless __KERNEL__ is
defined. I believe that this is incorrect.

I have checked the i386 and s390 versions of atomic.h and they declare
the atomic functions regardless of the status of the __KERNEL__ macro.
Therefore I propose that it should be removed from asm-ppc/atomic.h, and
have attached a patch to effect this.

With this patch applied, I am able to compile libCommonC++.

Ben Stanley.
