fcb0203141 First-cut at code to spin up secondary processors on a multiprocessor 
Alpha system, conditional on MULTIPROCESSOR.

NOTE: This does not yet work completely.  The secondary CPU begins the
boot process, but never makes it into the cpu spinup trampoline.  This
is merely a snapshot of a work-in-progress.

5b01d45ac4 Add a `-b #' option and logic for locating the secondary boot image via 
an absolute block address. It's cheating, as the motivation is support for
the libsa ustar tfs `filesystem' and the solution symmetrical to ufs and
cd9660 would have been to teach installboot about tfs. However, it still
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.

the reaper to free them for us, once it is safe to do so (i.e. we are
no longer running on the dead proc's vmspace and stack).

5fa7eee1ff don't define __BUS_SPACE_COMPAT_OLDDEFS by default. As stated in 
bus_space(9), if drivers want it (they shouldn't; easy to convert) they

the interfaces were (slightly) changed, and no code in the source tree
uses the old interfaces as far as I can tell.

people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access.  (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

is
6054d626f9 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
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
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
possible).

ff376fbd03 Doh! Jason caught me being really stupid. There isn't necessarily

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.
