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

Like the 1000A, the AlphaServer 1000 has a daughtercard assembly that

New systype, and, sigh, another way of doing interrupts and another
mystery icu.
Kill off some EVCNT_COUNTERS calls, since [A] it has to be rewritten anyway
before it can be useful, and [B] #ifdefs do not belong at every call site,
a common API should be defined and the implementations conditionalized, not
all the calls. Duhh.

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.

Several changes to the TurboChannel Dual SCSI driver:
...
- Fix the autoconfiguration model; the TCDS children don't attach to
TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
TurboChannel driver (i.e. work on DECstations).

Step 1 of the Grand Alpha Pmap Rototill:
...
- Clean up pmap_bootstrap() some, and make a slight change to how the
PROM mappings are saved.
- Give each pmap its own level 1 page table, rather than sharing a global
level 1 page table. This will eventually allow for Very Large user
address spaces.
- Keep a list of all pmaps, so that when kernel level 2 page tables are
allocated, all level 1 tables may be updated.
- Add a couple of functions for allocating and freeing page table pages.
- Add a few comments about ASN allocation.
