cgd 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.

tv 00ede2160e Change ddb_init() for a.out to provision for kernels which are not booted by
the current 'bootblock' method, like the Shark, which preloads and preformats
the symbol table right in the boot code.

is 7a0f63f982 Back out the defopt for M680?0. As pointed out to me, this breaks ports which
dont use the M680?0 the way Amiga, Atari, Mac68k, and X68k do. I must have
missed this in the past discussion about this project.

is 6a6812fd92 Move M680[2346]0 to opt_m68kcpu.h.
XXX Some explicit dependencies could be removed now from the individual
arch/$ARCH/conf/Makefile.$ARCH files, but this is still to be done.

thorpej 6626878e7b It is no longer necessary for pmap_pinit() and pmap_release() to be
pmap interface functions, as NetBSD no longer uses statically allocated
pmaps (except for the kernel pmap, which is special-cased anyhow).

tv b21bfbde11 Add -Wno-main conditional on compiler being gcc 2.8 or egcs. (This adds
a HAVE_GCC28 check-variable that can now be used to add other gcc-2.8
flags in cases where they may be useful, or to remove gcc 2.7.2 "bug
workaround" flags.)

cgd 3bbb7f7d45 Move pmap_map() function definition to MD headers, as appropriate. It's
an internal function, and the VM system shouldn't try to prototype it.
(Note that some ports _don't_ prototype it.)

scottr f49dd3ef30 Avoid declaring the "astpending" and "want_resched" globals in cpu.h,
as this breaks C++ code that happens to indirectly include this header.
Both Matthias Scheler and I noticed this, independently.

This problem notably does not affect the atari and sun3/sun3x ports,
which have already implemented a similar solution.

thorpej a8f80ad4fd Fix a bogosity apparently inherited from when the Utah 4.3BSD code base
was converted to use Mach VM for Net2/4.4BSD.  The user segment table
pointer was originally stored in the PCB.  When Mach VM came along,
however, it was also stored in the pmap, and loaded into the PCB in
pmap_activate().  pmap_activate() would then note that the PCB's USTP
was now in sync with the pmap's USTP, and the low-level context switch
code would use the value from the PCB.

However, pmap_activate() would also load the hardware MMU context if
the pmap was the current pmap (or, in the case where pmaps can be shared,
such as in NetBSD, if the proc was the current proc).  The low-level
context switch code would then reload the hardware _again_ using the
USTP from the PCB.

However, the optimization of not calling pmap_activate() if "stchanged"
was false ended up causing some processes to use stale USTP values from
the PCB when the low-level context switch code reloaded the hardware!
This was noticed by using a real vfork(2) (which worked for some time
before failing, surprisingly!)

Since I'm hard pressed to find any real optimization here (since the
hardware was always reloaded once, sometimes twice!), the code now always
calls pmap_activate(), which uses the correct USTP value (the one in the
pmap).  The PCB's USTP is now ignored, and should eventually be g/c'd.

Another optimization can actually be performed, and I have added a comment
describing what it is, but have not yet implemented it.

Also note that most of the loadustp() functions where actually incomplete.
This has been corrected.  These functions should probably be split up into
MMU-specific operations, and called indirectly, rather than doing constant
run-time decision making based on values that will never change during the
course of a boot's lifetime.
