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.

no longer running on the dead proc's vmspace and stack).

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).

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.

 * these are just the actual hard TL node IDS that we

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
