21144e2fde Brought back schedsofttty() (SMPng casualty). Didn't bring back the
other schedsoft*() functions since they have never been used.

Removed confused comment about not needing these functions.  The
functions delay scheduling of SWIs until the next hardclock tick.
For devices that only deliver a few characters per interrupt, this
reduces the number of calls to the scheduler by a large factor (about
115 for each sio port at 115200 bps).

33510ef17a Unpessimized CURSIG(). The fast path through CURSIG() was broken in
the 128-bit sigset_t changes by moving conditionally (rarely) executed
code to the beginning where it is always executed, and since this code
now involves 3 128-bit operations, the pessimization was relatively
large.  This change speeds up lmbench's pipe latency benchmark by
3.5%.

Fixed style bugs in CURSIG().

fbbeeb6cd6 Uninlined CURSIG() and unpolluted <sys/signalvar.h>. CURSIG() had become
very bloated, first with 128-bit sigset_t's, then with locking in the
SMP case, then with locking in all cases.  The space bloat was probably
also time bloat, partly because the fast path through CURSIG() was
pessimized by the sigset_t changes.  This change speeds up lmbench's
pipe-based latency benchmark by 4% on a Celeron.  <sys/signalvar.h>
had become very polluted to support the bloat.

e645a1ca27 change the evaluation order of the rsvp socket in rsvp_input()
in favor of the new-style per-vif socket.

this does not affect the behavior of the ISI rsvpd but allows
another rsvp implementation (e.g., KOM rsvp) to take advantage
of the new style for particular sockets while using the old style
for others.

in the future, rsvp supporn should be replaced by more generic
router-alert support.

3ff1a2f43e Add new flag PDIRUNLOCK to the component.cn_flags which should be set by
filesystem lookup() routine if it unlocks parent directory. This flag should
be carefully tracked by filesystems if they want to work properly with nullfs
and other stacked filesystems.

VFS takes advantage of this flag to perform symantically correct usage
of vrele() instead of vput() if parent directory already unlocked.

If filesystem fails to track this flag then previous codepath in VFS left
unchanged.

Convert UFS code to set PDIRUNLOCK flag if necessary. Other filesystmes will
be changed after some period of testing.

7b9e034490 Both boot and boot-conf were using a different algorithm from the one
used by start to find the kernel. Fix this.

Also, boot would proceed immediately in the absence of a path as
argument. Check first if a kernel has already been loaded, and, if
not, fall back to load kernel&modules behavior.

Some further factorizing. I deem this code to be mostly readable by
now! :-)

45713b37cd Change the interface to pccard_function_init. The interface is such
that it looks for an acceptible one.  Once it finds it, it should set
the resources for the device.  I say "should" because I've not written
that.  Also set an ivar for the child of pccard.  Minor fix to the
attach message printed, we lose the slot number, which I'll have to
restore later.  Adjust the pccard ivar so that we can save the
function that corresponds to this driver so we can enable and disable
it more easily.  Save a pointer to the function so we know what we're
dealing with.

There should be some way for the driver to specify which cfg it wants
to activate.  For now the pccard_function_init function just picks
one, but we'll have to revisit this going forward.  I'm not doing it
now because I'd need some way to activate the card many times and I'm
not sure that is desirable or even safe with some cards.

1cb190742f Factorize, reorganize, and move code around.
The boot-conf and boot code had various bugs, and some of it was big,
ugly, unwieldy, and, sometimes, plain incorrect. I'm just about
completely replaced these ugly parts with something much more manageable.

Minor changes were made to the well-factorized parts of it, to accomodate
the new code.

Of note:

	* make sure boot-conf has the exact same behavior wrt boot order
as start.

	* Correct both boot and boot-conf so they'll work correctly when
compiled in, as they both had some bugs, minor and major.

	* Remove all the crud from loader.4th back into support.4th, for
the first time since boot-conf was first improved. Hurray!

I'm fairly satisfied with the code at this time. Time to see about those
man pages...
