8abe0d6b1c Adjust for the new "reaper" kernel thread: do not free the vmspace and 
u-area in machine-dependent code.  Instead, call exit2() to schedule
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).

* Add a driver for the Yamaha OPL[23] FM synths.

Makes the whole concept useless. This is for default printouts. If you
can build a debug kernel, you know what version you have. This was under
the concept of 'RAS' so that hapless users could tell you microversion
things. But I guess this isn't the right way according to our local
Jesuits. Oh, well. I'll think up something different and hopefully
less objectionable. And yes, NetBSD isn't linux. The developers seem
to be equally bad tempered, but linux is more successful.

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.
