Subject: [PATCH] alpha: Fix percpu for !SMP
Commit 9267b4b3880d00dc2dab90f1d817c856939114f7 introduced a
percpu.h for alpha. It didn't define PER_CPU_ATTRIBUTES for
the non-SMP case, leading to build failures for such a config
(e.g., the alpha defconfig).
Fix this by defining PER_CPU_ATTRIBUTES to empty at the end of
asm-alpha/percpu.h if it wasn't already defined, just like the
asm-generic version does. The SMP && !MODULE case can drop its
own definition now as well.

This is needed for 2.6.26, it's a regression fix.
