SubjectRe: mm->context[NR_CPUS] and pci fix check [was Re: Alpha SCSI error on 2.4.0-test11]
   Date: 	Fri, 1 Dec 2000 15:18:42 +0100
From: Andrea Arcangeli <andrea@suse.de>

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.

Later,
