As I noted to you in my first response to you, I did everything I could
to get a system call to do pinning. It is not that hard to do, and I
have created primitive patches towards this in the past, except that it
will not go into 2.4. No SGI scret there ...

FWIW, on IRIX, you _can_ turn off the timer interrupt on specific cpus,
as well as IPIs, but these were a headache to get right ... probably
worth it, just to be able to claim realtime latencies ....

See above ...
