a NULL argument. Some programs change the contents of the argv
array, typically to remove some special arguments. They shorten
argv by storing a NULL where an argument pointer used to be. Such
programs core dumped if they called setproctitle(), because it
would try to apply strlen() to a NULL pointer.
on. So stop failing the attach if the IRQ is unassigned. With this
patch, I can now boot with PNP-OS YES in my BIOS no differently than
PNP-OS NO (which is a good thing since Windows hangs with PNP-OS NO).

make sure there is exactly one prototype for each function,
use K&R style definitions everywhere to match dominant style,
make flag_signal take an int to avoid problems if we have
ANSI prototypes and K&R definitions.
- standardise error reporting for commands
- simplify the driver-to-controller bio transfer
- add bio in/out accounting
- correctly preserve the command ID in twe_ioctl (thanks to joel@3ware)
pushl that of the new process, rather than doing a movl (%esp) and
assuming that the stack has been setup right. This make the initial
stack setup slightly more sane, and will make it easier to stick
an interrupted process onto the run queue without its knowing.
Remove some PNP-related dead code that is unlikely to survive the
changes in -current PNP anyway.

and numvnodes are longs in the kernel. They should remain longs in systat,
what really needs to change is that they should be using SYSCTL_LONG rather
than SYSCTL_INT. I also changed wantfreevnodes to SYSCTL_LONG because I
happened to notice it.
I wish there was a way to find all of these automatically..

There is no more TAILQ fifo to harvest the entropy; instead, there
is a circular buffer of constant size (changeable by macro) that
pretty dramatically improves the speed and fixes potential slowdowns-
by-locking.
Also gone are a slew of malloc(9) and free(9) calls; all harvesting
buffers are static.
All-in-all, this is a good performance improvement.
Thanks-to: msmith for the circular buffer concept-code.
(specifically, how many entries we've looked at so far). Maintain
interrupt instrumentation. Use USEC_SLEEP instead of USEC_DELAY in
a number of places (this allows us to drop locks and sleep instead
of spin). Track changes to configuration options for topology preference.
Fix botched order of printout for Channel, Target, Lun.
from struct proc, which are now unused (p_nthread already was).
Remove process flag P_KTHREADP which was untested and only set
in vfs_aio.c (it should use kthread_create). Move the yield
system call to kern_synch.c as kern_threads.c has been removed
completely.
