579f45fa60 Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it.  Driver writers can do
this if it's not defined.  (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

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.

ecbb00a262 This commit fixes various 64bit portability problems required for
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.
