I'm still left the #ifdef __alpha__ around the context[NR_CPUS] to avoid breakage of other archs but that should be probably removed: any CPU with per-CPU ASNs like alpha needs per-CPU per-MM context information to avoid wasting ASNs when the task migrate CPU or with threads.
I would instead suggest to declare 'context' to be of an arch-specific defined type, much like "thread_struct" is.
For example, I don't need NR_CPUS contexts in the mm_struct on sparc64, my allocation just works differently, so I shouldn't eat all the space.
