44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

99b8465544 Introduce the concept of "default" voltage. Have pccard layer use this
value (-1) in lue of 50 (which assumes a 5.0V card).  The rest of the
pccard system doesn't detect the proper voltage for the card, so we have
to do it on powerup.  Many (all?) 3.3V cards can tolerate 5.0V for reading
the CIS, but may fail to operate properly when so powered.

7cf44afd1a <jkh> "Hey Rocky, watch me eject this pccard outta my laptop!" "What,
again?  That NEVER works!"  "This time for sure!"

Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
	o Reintroduce func_intr and func_arg and use the to store the
	  interrupt handler to call.
	o Create a pcic_pci_func_intr to call the real interrupt handler
	  iff the card hasn't been ejected.
	o Remove some checks in pcic_setup_intr now that it is used
	  exclusively for isa routed interrupts.
	o Defer the eject event until later too, but make sure we can't
	  do any client driver ISR calling in the interrum.
	o Add some simple code to make sure that we don't attach more
	  than one child.  This should fix pccardd starting twice
	  problem (ala single user -> multi-user when you started pccardd
	  by hand in SU).

MFC: after jkh thinks I've put the crack pipe away.

372458622f A bunch of interrupt related cleanup.
o Move PIOCSRESOURCE from pccard to pcic so the kernel can give pccardd
  better hints as to what resources to use.
o Implement an undocumented hw.pcic.interrupt_route to allow people that
  need to do so to route their interrupts in a non-standard way.
o Only preallocate a resource in probe if we're routing via pci.
o If we aren't routing via pci, then set the irq to use explicitly
  to defeat the automatic IRQ routing of the pci layer.

This, with the pccardd code should be close to what can be committed

o Delete unused variable wasinactive.
o return 0 from pccard_resume.

o move comment above code for interrupt dispatching.
o Powerstate interface is now available as of 430002, not 500000 (note that

  enter current until well after 500000, but it is good enough for the two

c1c1a23f53 Attempt to fix and document interactions between suspend/resume and pccardc
power x 0.

pccardc power x 0 used to disable the slot.  But a suspend/resume
would reactivate the pccard.  It no longer does that.  Now the
disabling of the slot is sticy until it is reset with power x 1 or the
card is ejected.  This seems closer to correct behavior to me.

o Process all card state changes the same using pccard_do_stat_change().
o Cleanup disabling the card so that we can preserve the state after
  the change.  Basically, don't set it to empty as often as we do.
o On suspend, the new state is "empty" and the laststate is "suspend"
o Document state machine with a diagram of states and edges.  The
  edges are labeld to tell the reader what event causes the external
  state changes.
o "machdep.pccard.pcic_resume_reset" may be obsolete now.  We always
  call the bridge driver's resume method on resume now.  Otherwise cards
  won't automatically show up.  If it needs to stay, I'll add it back.

bf968b1638 First step towards plugging the "pccard is trying to map into a BIOS
region for CIS reading" problem:

Use bus_alloc_resource to get the memory that we'll be using.  Also
has the benefit of doing usage checking as well.  This gets rid of the
ugly kludge that we had before for mapping pmem to vmem.

Second, move PIOCSRESOURCE to its own routine and make it conform more
to style(9) in the process.

6817e978cf Place the call to pccard_insert_beep() in the inserted() timeout
routine instead of pccard_event(). This avoids spurious extra calls
to pccard_insert_beep() at insert or remove time which could occur
due to noise on the card-present lines.

Clean up some code in pccard_beep.c; we were depending on the order
of evaluation of function arguments, which is undefined in C. Also,
use `0' rather than `NULL' for integer values.

975ce2575a fix some minor problem in PIOCSRESOURCE ioctl.
- If resource which was allocated for pcic was
  requested via this ioctl, bus_alloc_resource
  would be succeeded and that resource was
  returned as free resource.  So check whether
  requested resource was used for pcic or not
  before bus_alloc_resource test.

- merge SYS_RES_IRQ routine into other SYS_RES_*
  routine and clean up.

a7da6b679e This fixes a bug that /etc/pccard_ether did not work without DHCP.
For example, when /etc/pccard.conf had ed0 in config line, but kernel
refused this name and said

devclass_alloc_unit: ed0 already exists, using next availale unit
number

Kernel used ed1 as device name and it did not match with config and
insert/remove lines.  Fortunately, dhclient was called without args,
and it works, but if we wanted to use static IP address for PC-card,
it did not work.

This modification makes pccardd to execute insert/remove lines with
the true device name that returns from kernel.  (Last change to
etc/pccard.conf.sample eliminated all hardwired device name from
insert/remove lines in /etc/pccard.conf)

Should have no effect, but does make things a little cleaner.  I
thought this was the race that was causing problems, but it turned out
to be in pccardd waking up after the empty/insert events had happened
and being confused.

o remove extra from controller
o formatting nits
o use PCCARD_DEVINFO(d) rather than a bare device_get_ivars(d)

8d29af8945 Fix alloc_driver() so that calls devclass_get_device() with slt->slotnum
as the unit argument instead of 0. disable_slot() calls
devclass_get_device() correctly, however because alloc_driver() does
it wrong, disable_slot() is unable to locate the child devices
attached to the pccard bus and thus fails to call device_delete_child()
on them. The end result is that when a card is removed, its detach
routine is never called, and re-insertion always fails.

With this fix (and the previous one to if_wi.c), I can now insert,
remove and re-insert my WaveLAN/IEEE card and things behave correctly.
kldunloading the if_wi.ko module also seems to work properly now.

fe0d408987 Remove the 'ivars' arguement to device_add_child() and

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
