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).

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.

Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG)

is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used. If they are not, a message will be displayed on
the console.
Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed. These changes will aid debugging
of broken device drivers.

Add fine-grained locking, using a locking protocol modeled after the i386

UVM pmap's locking protocol, written by Chuck Cranor. Not all of the

under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).

to take a look at.
