5881492684 Fix fork_exit() to take a pointer to a function that returns void as its 
first argument rather than a function that returns a void *.

17984f33e4 Update some comments, s0 in the pcb of a child returning from fork1() is 
now passed in as a0 to fork_exit() and and s2 is passed in as a1.

3366175318 Minor cleanups after yesterday's patch. 
The code (bridging and dummynet) actually worked fine!

10b4b1aae3 The osfulator needs sysvipc to work. Thanks to DES's commit to 
the i386 linulator for pointing this out.

The alpha linulator doesn't need a dependancy, as it already
depends on the osfulator.

Thanks a lot to Jakob Schripsema (sch@kpn.com) for pointing out similarities
of the Eicon 2.02 to the Siemens I-surf driver !

e1ad448f1d Add experimental support for Eicon.Diehl DIVA 2.0 and 2.02 ISA PnP cards. 
Increment i4b minor revision (=step) so a buildworld or a make install in
/usr/src/sys/include is necessary to get isdnd and i4b kernel parts in sync.

ce34393882 - Don't pass in MTX_NORECURSE, as that is only used with spin mutexes and 
is going away soon anyways.  Instead, don't pass MTX_RECURSE to mtx_init,
  so that WITNESS will panic if the driver mutex is recursed on.
- Use MTX_DEF in mtx_init() instead of assuming that it will be 0.

fe01c653ba Consider that the chipset may be in ECP mode (from BIOS settings) 
even if mode PS/2 is forced with bootflags. As a matter of fact,
chipsets needs some extra configuration for accessing PS/2 mode
from ECP. The current patch is only relevant for generic chipsets
since specific code is supposed to deal with this during detection.
