Doh! Jason caught me being really stupid. There isn't necessarily
...
a linear 0..N mapping out of alpha_cpu_whami - which is what I was
using to index the new cpu machine check array. This is a quick hack
back to just using the first element while I think of a kinder function
that will do the function (per-platform) of whami->VIRTUAL CPU ID, which
if you think about it, is really necessary anyway.

use by an error handler:

* in them (irrespective of how many CPUs they have).

There can only be one TurboLaser node, and now we'll overload

into the integer tlsb_found a bit map of found nodes and export

have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).
