if the childs exec() has succeeded or failed by taking advantage
of the fact that both processes share the same memory.
FWIW:
I tried to implement this by doing a pipe(), setting the
write desciptors close-on-exec flag in the child and writing
errno to the descriptor if the exec() fails. The parent can
then ``if (read()) got errno else exec worked''.
This didn't work though - the child could write() to fd[1] on
exec failure, but the parent got 0 trying to read() from fd[0] !
Is this a bug in execve() ?
dropping out of background/foreground/direct mode.
This avoids either having to wait for the redial timer before
exiting or jaming up in select() waiting for something that'll
never happen.
Remove a bogus (redundant, just weird, etc.) key_freeso(so).
There are no consumers of it now, nor does it seem there
ever will be.
in6?_pcb.c:
Add an if (inp->in6?p_sp != NULL) before the call to
ipsec[46]_delete_pcbpolicy(inp). In low-memory conditions
this can cause a crash because in6?_sp can be NULL...
file and start over.
Also note that we're in the traditional whack-a-ball kernel model/api
reorg for 5.0 and that one needs to be extra careful about making sure
models and kernels are in sync.
On a K6-2/450 with fairly fast SCSI disks, building+installing src/share/
takes 2m51.3s, where src/share/doc/ is 1m9.9s of that.
However on a slow Alpha (233MHz) the times are 7m39.3s and 4m58.3s
respectively.
This commit allows one to speed up their build time, without not getting
any important and required changes if one used "NOSHARE".

This makes it easy to create a new DDB command, which is the big reason
for the change. You can now do the following in DDB:
Example rc.conf entry:
dumpdev="/dev/ad0s1b" # Device name to crashdump to (if enabled).
db> show disk/ad0s1b
dev_t = 0xc0b7ea00
db> p *dumpdev

* add a callback for initialising the mixer interface
* support ac97 2.1 variable rate audio feature
fix ac97-using drivers for the above
add suspend/resume support for neomagic
