b40ce4165d KSE Milestone 2
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

fb919e4d5a Undo part of the tangle of having sys/lock.h and sys/mutex.h included in
other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

1b7277516b Commit the remaining part of PR14914:
Alot of the code in sys/kern directly accesses the *Q_HEAD and *Q_ENTRY
   structures for list operations.  This patch makes all list operations
   in sys/kern use the queue(3) macros, rather than directly accessing the
   *Q_{HEAD,ENTRY} structures.

1168ab0815 Fixed corruption of the "blocked" list in lf_setlock() when tsleep()
returns 0 after ptrace() attach and/or detach doesn't quite quite
deliver a signal.  Perhaps the process shouldn't be woken in this
case, but avoiding the problem is easy.

PR:		12247

Fixed a couple of places where mechanical fixing of compiler warnings
caused misspelling of NOLOCKF as NULL.

a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.

remembered the trick to making things static:  Put "static" in front of
them.

a8687b6dcd Added some ufs #includes so that this compiles with option LOCKF_DEBUG.
Moving this all from ufs wasn't a good move.  At least the debugging
routines depend on the file system.

Cleaned up the LOCKF_DEBUG #includes.

996c772f58 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

Boy, I'm glad we're not using sup anymore.  This update would have been

b71fec07db Eliminated nested include of <sys/unistd.h> in <sys/file.h> in the kernel.

nothing.

bb56ec4a05 While in the real world, I had a bad case of being swapped out for a lot of
cycles.  While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent).  So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there.  Having a lap-top is
highly recommended.  My kernel still runs, yell at me if you kernel breaks.

92dc7331c9 Made lockf advisory locking code generic (rather than ufs specific), and
use it in NFS. This is required both for diskless support and for POSIX
compliance. Note: the support in NFS is only for the local node.
