Please add patch to the source tree..

Hello

In the kernel source 2.6.14 from kernel.org build with the given config1, the
symbol barrier() is missing in linux/include/asm-alpha/atomic.h with gcc 4.0.1 from
FC4.

This is defined in linux/compiler.h or asm/compiler.h.

An alternative patch has already been merged into Linus' git tree. It should 
fix your problem.
