9c170fd168 Disable the option VFS_ALLOW_NONMPSAFE by default on all the supported
platforms.
This will make every attempt to mount a non-mpsafe filesystem to the
kernel forbidden, unless it is expressely compiled with
VFS_ALLOW_NONMPSAFE option.

This patch is part of the effort of killing non-MPSAFE filesystems
from the tree.

No MFC is expected for this patch.

723616952d At the risk of reducing source compatibility with old NetBSD and Sprite:
o) Get rid of some unused macros related to features we don't intend to
   provide.
o) Get rid of macro definitions for MIPS-I CPUs.  We are not likely to
   support anything that predartes MIPS-III.
o) Respell MIPS3_* macros as MIPS_*, which is how most of them were being
   used already.
o) Eliminate a duplicate and mostly-unused set of exception vector macros.

There's still considerable duplication and lots more obsolete in our headers,
but this reduces one of the larger files to a size where one could reckon
about the correctness of its contents with a mere few hours of contemplation.

There is, of course, a question of whether we need definitions for fields,
registers and configurations that we are unlikely to ever use or implement,
even if they're not obsolete since 1991.  FreeBSD is not a processor
reference manual, and things that aren't used may be wrong, or may be
duplicated because nobody could possibly actually know whether they're
already defined.

0566170f70 Provide wbwd(4), a driver for the watchdog timer found on various
Winbond Super I/O chips.

With minor efforts it should be possible the extend the driver to support
further chips/revisions available from Winbond.  In the simplest case
only new IDs need to be added, while different chipsets might require
their own function to enter extended function mode, etc.

6fa3bc4f91 Store TLS base in the sigframe just as is done in freebsd32_sendsig. Because
the native sigreturn doesn't use set_mcontext like the COMPAT_FREEBSD32 version
does, this wouldn't actually result in overwriting the TLS base.  Probably it
makes sense to restructure the native sigreturn to use set_mcontext for
consistency, and to allow sigreturn to change the TLS base.

bdf4700515 Fix two and a half oversights in COMPAT_FREEBSD32 related to contexts and
TLS:
o) The mc_tls field used to store the TLS base when doing context gets and
   restores was left a pointer and not converted to a 32-bit integer.  This
   had the bug of not correctly capturing the TLS value desired by the user,
   and the extra nastiness of making the structure the wrong size.
o) The mc_tls field was not being saved by sendsig.  As a result, the TLS base
   would always be set to NULL when restoring from a signal handler.

Thanks to gonzo for helping track down a bunch of other TLS bugs that came out
of tracking these down.

ea6ed0ba9f Fix boot2 to handle boot config files that only contain a custom path to
a loader or kernel.  Specifically, kname cannot be pointed at cmd[] since
it's value is change to be an empty string after the initial call to
parse, and cmd[]'s value can be changed (thus losing a prior setting for
kname) due to user input at the boot prompt.  While here, ensure that that
initial boot config file text is nul-terminated, that ops is initialized
to zero, and that kname is always initialized to a valid string.

2651e350d3 Revert r232473. I have been convinced by Doug Barton and Bjoern Zeeb
that it is better to error out when people attempt to build using the
wrong bsd.*.mk files, than to silently ignore the problem.

This means, that after this commit, if you want to build kernel modules
by hand (or via a port) from a head source tree, you *must* make sure
the files in /usr/share/mk are in sync with that tree.  If that isn't
possible, for example when you are running on an older FreeBSD branch,
you can:

- Run "make buildenv" from your head source tree, to have the correct
  environment setup.  (It's advisable to have run "make buildworld", or
  at a minimum "make toolchain" first.)
- Alternatively, set MAKESYSPATH to the share/mk directory under your
  head source tree.  If your build tools are too old, other problems may
  still occur.
- Alternatively, use "make -m" and specify the share/mk directory under
  your head source tree.  Again, build tools that are too old may still
  result in trouble.
