4545c62547 Edit the interrupt name strings to shorten them. This is believed to
only affect amd64 and i386.  alpha uses "intr N" instead of "irqN" and
mostly has no device names.  ia64 uses only device names.

- Edit interrupt names once after they are read from the kernel and not
  every time they are displayed.
- Discard bogus trailing spaces so that the next step doesn't move things
  to oblivion.
- If an interrupt name starts with "irqN:" (as it usually does in on
  amd64 and i386), then move "irqN" to the end and strip ":", since we
  have no space for the ":" and don't want to start descriptions with
  "N" after stripping "irq" in the next step (since "N" would look like
  a count).  This step may need reworking for interrupt names containing
  several device names -- then moving the irq number to the end would
  lose it instead of losing some device names.
- Remove "irq" from an interrupt name if and only if the original name is
  too long to display.

18d3a03e13 Backed out rev.1.49 since it had buffer overruns and only worked
accidentally.

Read buffer overruns:
The size of the target array (TSOTTA == 10) is a wrong limit to use for
scanning the source string.

Write buffer overruns:
TSOTTA is also a wrong limit to use for copying to the target buffer,
since we want to add a NUL terminator afterwards.  TSOTTA was also 1
too small for holding both the desired number of visible characters
and the NUL.

Worked accidentally:
There is error in the algorithm that tends to result in the space saved
by stripping "irq" not actually being used, but some cases worked
accidentally provided "irqN" is near the end of the source string and
"N" is only 1 digit.

Starting with 5.mumble-CURRENT, "irqN" is at the beginning of the
string on all (?) arches that have it and the accidents don't happen.
E.g. on i386's, the keyboard irq is now named
"irq1: atkbd0<bogus blank padding>" by the kernel, and this name was
converted to "1: atkb" -- not only the device number but part of the
device name has been lost --, while before 5.mumble the kernel name
was "atkbd0 irq1" and systat accidentally preserved the irq number to
give "atkbd0 1".  The ":" in the string wastes precious space, and
stripping "irq" results in descriptions starting with numbers which
makes them look too much like counts.  This commit just fixes the last
problem.

e76bdda079 Abbreviate long field descriptors at write time so that they don't get
clobbered at runtime:
    dirtybuf -> dtbuf
    desiredvnodes -> desvn
    numvnodes -> numvn
    freevnodes -> frevn
The vmstats column has only 5 characters available for descriptors, but up
to 13 were used.  The extras get clobbered at runtime by interrupt values
and/or descriptors on systems with more than 12 interrupt sources.
    %slo-z -> %sloz
This one is in the "extended" vmstats area and doesn't get clobbered now.

Removed stale documentation of desvn.

Changed a descriptor:
    tfree -> totfr
so that it is consistent with the abbreviations for other free counts
(daefr and prcfr) and thus almost decodeable.

Fixed missing documentation of tfree/totfr.  This and everything else
in the extended vmstats area is misdocumented as being in a certain
place in the vmstats column.

55a5ff0140 Add auto upgrade capability to mergemaster.
An mtree description of all non-zero files that make
distribution installs (only size and md5) is built from the
temproot.  When the user completes a mergemaster run, the
mtree description file gets installed into /var/db for
safe-keeping.

When the user then decides to do a subsequent upgrade (with
the -U flag), the existing mtree description from /var/db
is called into service looking for files that are different in
DESTDIR. This is stashed away until a file that would normally
end up prompting the user to look at changes is encountered.
Since there are no user modified changes, the new file is
installed without bothering the user.

Marcel Moolenaar
64220a7e28 Rewrite of puc(4). Significant changes are:
o  Properly use rman(9) to manage resources. This eliminates the
   need to puc-specific hacks to rman. It also allows devinfo(8)
   to be used to find out the specific assignment of resources to
   serial/parallel ports.
o  Compress the PCI device "database" by optimizing for the common
   case and to use a procedural interface to handle the exceptions.
   The procedural interface also generalizes the need to setup the
   hardware (program chipsets, program clock frequencies).
o  Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
   default and non-serdev devices are handled by the bus.
o  Use the serdev I/F to collect interrupt status and to handle
   interrupts across ports in priority order.
o  Sync the PCI device configuration to include devices found in
   NetBSD and not yet merged to FreeBSD.
o  Add support for Quatech 2, 4 and 8 port UARTs.
o  Add support for a couple dozen Timedia serial cards as found
   in Linux.

f088002825 The nvidia binary blob sometimes defers tx completion notification to the
OS dependent layer.  Thus, the watchdog timer can go off when the tx
engine is working fine but the OS dependent layer just hasn't been called
to cleanup finished tx transactions.  To workaround this, when the watchdog
fires, poke the binary blob to force it to flush any pending tx
completions.  If this drops the pending tx count to zero then just return
without logging a message or resetting the chip.

This reportedly fixes the 'device timeout()' errors with at least several
NF4 nve(4) parts.

stations that are associated by making ieee80211_find_txnode return
NULL when a unicast frame is to be delivered to an unassociated
station.  This will be handled differently in the future but for
now putting the check here allows all drivers to immediately do
the right thing.

7eeda22793 Interim fix for pmap problems I introduced with my last commit.
Remove the code to dyanmically change the pv_entry limits.  Go back
to a single fixed kva reservation for pv entries, like was done
before when using the uma zone.  Go back to never freeing pages
back to the free pool after they are no longer used, just like
before.

This stops the lock order reversal due to aquiring the kernel map
lock while pmap was locked.

This fixes the recursive panic if invariants are enabled.

The problem was that allocating/freeing kva causes vm_map_entry
nodes to be allocated/freed.  That can recurse back into pmap as
new pages are hooked up to kvm and hence all the problem.
Allocating/freeing kva indirectly allocate/frees memory.

So, by going back to a single fixed size kva block and an index,
we avoid the recursion panics and the LOR.

The problem is that now with a linear block of kva, we have no
mechanism to track holes once pages are freed.  UMA has the same
problem when using custom object for a zone and a fixed reservation
of kva.  Simple solutions like having a bitmap would work, but would
be very inefficient when there are hundreds of thousands of bits
in the map.  A first-free pointer is similarly flawed because pages
can be freed at random and the first-free pointer would be rewinding
huge amounts.  If we could allocate memory for tree strucures or
an external freelist, that would work.  Except we cannot allocate/free
memory here because we cannot allocate/free address space to use
it in.  Anyway, my change here reverts back to the UMA behavior of
not freeing pages for now, thereby avoiding holes in the map.

ups@ had a truely evil idea that I'll investigate.  It should allow
freeing unused pages again by giving us a no-cost way to track the
holes in the kva block.  But in the meantime,  this should get people
booting with witness and/or invariants again.

Footnote: amd64 doesn't have this problem because of the direct map
access method.  I'd done all my witness/invariants testing there.  I'd
never considered that the harmless-looking kmem_alloc/kmem_free calls
would cause such a problem and it didn't show up on the boot test.

more complete and accurate content, better advice, etc, that could be added

Per scottl's suggest, add a small piece of moralizing text regarding the
fact that sysctl names quickly get embedded in system configuration files,
libraries, third party applications, and even books, so renaming and
removing names after they've been published is a tricky issue.
