fee4d88e0f Fix "Duplicate mbuf free panic".
The cause of "Duplicate mbuf free panic" is in the programming
error of hme_load_txmbuf(). The code path of the panic is the
following.

1. Due to unknown reason DMA engine was freezed. So TX descritors
   of HME become full and the last failed attempt to transmit a
   packet had set its associated mbuf address to hme_txdesc
   structure. Also the failed packet is requeued into interface
   queue structure in order to retrasmit it when there are more
   available TX descritors.

2. Since DMA engine was freezed, if_timer starts to decrement its
   counter. When if_timer expires it tries to reset HME. During
   the reset phase, hme_meminit() is called and it frees all
   associated mbuf with descriptors. The last failed mbuf is also
   freed here.

3. After HME reset completed, HME starts to retransmit packets
   by dequeing the first packet in interface queue.(Note! the
   packet was already freed in hme_meminit()!)

4. When a TX completion interrupt is posted by the HME, driver
   tries to free the successfylly transmitted mbuf. Since the
   mbuf was freed in step2, now we get "Duplicate mbuf free panic".

However, the real cause is in DMA engine freeze. Since no fatal
errors reported via interrupts, there might be other cause of
the freeze. I tried hard to understand the cause of DMA engine
freeze but couldn't find any clues. It seems that the freeze
happens under very high network loads(e.g. 7.5-8.0 MB/s TX speed).

Though this fix is not enough to eliminate DMA engine freeze it's
better than panic.

0fac1537a2 It was noticed that we do not change a file's access time when it gets
executed.  This appears to violate most of the UNIX-ish standards.
One example quote from:

  http://www.opengroup.org/onlinepubs/009695399/functions/exec.html

    Upon successful completion, the exec functions shall mark for update
    the st_atime field of the file. If an exec function failed but was
    able to locate the process image file, whether the st_atime field is
    marked for update is unspecified. Should the exec function succeed,
    the process image file shall be considered to have been opened with
    open().

This appears to take care of it for ufs filesystems, doing the necessary
sanity checks (read-only filesystem, etc) without violating any other
standards (setting atime for any open appears to be allowed in any standards
I could find).

8d2ad0b460 The two PLANEX cards listed in pccarddevs, identified only by their
CIS, weren't actually used anywhere (other than the generic PC Card
code when certain variables are defined).  They aren't used in NetBSD
either.  Make things simpler by removing them.  Change PLANEX_2 to
PLANEX and tweak wi and owi to use that instead.  The PLANEX id seems
to actually be pci ID assigned to planex, not its pcmcia id.  Ooops.
I don't know if this is a reporting error from where this entry came
from, or if it is a mistake on PLANEX's part.  I suspect the latter,
as ACTIONTEC and NEWMEDIA made the same mistake (although new media
may be because it uses an advansys chip inside).  Make a note of this
in the file.  The 0xc entires may be JEITA assigned, so note that as
well.

83820457eb Add a IEEE488 driver for PCIIA compatible cards.
This driver implements "unaddressed listen only mode", which is what
printers and plotters commonly do on GP-IB busses.

This means that you can capture print/plot like output from your
instruments by configuring them as necessary (good luck!) and

	cat -u /dev/gpib0l > /tmp/somefile

Since there is no way to know when no more output is comming you
will have to ctrl-C the cat process when it is done (that is why
the -u is important).

UART is designed as a keyboard port or not and thus whether we
can use the port as a TTY or not.
We now call sunkbd_attach() even when we didn't previously find
a keyboard. Emit a useful message stating that no keyboard was
found, but don't do anything else.

2554d6b9b4 Revert rev. 1.5.
It should be safe to attach to all Z8530 controllers again. In fact,
the keyboard works on Ultra 2 machines.

06456da2c6 Update an additional reference to the rate of ISN tick callouts that was
missed in tcp_subr.c:1.216: projected_offset must also reflect how often
the tcp_isn_tick() callout will fire.

0ba04c87b3 Change the state allocator from using regular malloc to using
a UMA zone instead. This should eliminate a bit of the locking
overhead associated with with malloc and reduce the memory
consumption associated with each new state.

54082796aa Have tcp_isn_tick() fire 100 times a second, rather than HZ times a
second; since the default hz has changed to 1000 times a second,
this resulted in unecessary work being performed.
