Subject: alpha: don't implement PER_CPU_ATTRIBUTES

from arch/alpha/kernel/srm_env.c:37:
include/linux/sched.h:138: warning: '__used__' attribute ignored
Fixed by removing the __used from PER_CPU_ATTRIBUTES
Ivan said:
It was intended for suppressing the compiler warnings about "unused"
static per-cpu variables, as they were only referenced inside the asm
code.
Now it seems to be broken with DECLARE_PER_CPU thing, so I think your
patch that kills __used attribute should go in as a compile fix ASAP -
we can live with a few compile warnings until the rest of percpu
patchset gets merged.
