134a826b50 Unbreak slot_irq_handler(). The problem here is that slot_irq_handler()
abuses its argument, which is supposed to be an integer unit number, as
a pointer to the head of the 'struct slot' list. When this code was
hacked^Wupdated for newbus, a new mechanism for registering slot_irq_handler()
was put in place and the significance of the unit number was overlooked.
When registering an interrupt, we have both device_id and unit. The unit
number is passed as 'unit' but /sys/i386/usa/intr_machdep.c:register_intr()
drops unit on the floor and uses device_id instead. Since pccard_alloc_intr()
always sets device_id to 0, this means the unit number is always zero, and
slot_irq_handler() is always called with 0, which becomes a NULL pointer
which slot_irq_handler() tries to dereference and the kernel explodes.

Result: if you assign a PCMCIA driver in the kernel config file like this:

device wi0 at isa? port? irq?

Then the system will panic the moment a PCMCIA device is attached and
an interrupt is triggered.

The quick fix: make pccard_alloc_intr() pass the unit number as both
the device_id and unit arguments to register_pcic_intr(). The correct fix
would be to rewrite /sys/pccard to be less disgusting.

f711d546d2 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

a1f7e1b4c5 Somehow, it is possible to get a pcicintr() when in the resume process.
This will trigger inserted()) to be called twice which confuses pccardd.

process. The real insertion of cards and the emulated one in the suspend/resume
code really do not mix up.

FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.
