Add a `-b #' option and logic for locating the secondary boot image via

would have been different as you can't mount a tfs with the kernel, and
this option gets possibly useful support for any contiguous format, even
completely raw boot images.

Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use

tty structures, and on some machines (namely the DraCo internal lpt, and some

interupt level would hurt serial performance.
On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were

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.

Clarify comment about what nodes are being 'found' and noted for later
...
use by an error handler:
* There can be only one TurboLaser, and we'll overload it
* with a bitmap of found turbo laser nodes. Note that
* these are just the actual hard TL node IDS that we
* discover here, not the virtual IDs that get assigned
* to CPUs. During TLSB specific error handling we
* only need to know which actual TLSB slots have boards
* 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
it to the rest of the kernel. This is so that at machine check
time when we're doing some TLSB/KFTXX error handling we don't
have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).

Start of the platform specific (RAWHIDE) machine check handler. This

is not really needed for this platform, except that we might want to
handle PCI errors which get reported through here. In any case, this
prints out more info than is usual. Will probably need to detune
this to be based upon DIAGNOSTIC defines.
