1d88dfe265 What:
o ToPIC is happy with two cards now, even when the two cards are
	  modems.
	o Fix (all?) hangs on boot when power is applied to the card.  I
	  suspect that this will make the Ricoh bridges happier and also
	  make a lot of VAIO owners happy (confirm to me in private email
	  please :-).
	o All Cardbus bridges should now support 3.3V, X.XV and Y.YV cards,
	  to the extent that the underlying hardware supports such cards.
	  (X.X and Y.Y haven't been assigned values yet :-).
	o Better 3.3V support for Ricoh ISA bridges.

How:
	o Don't mess with the power register when scanning the cards.  It
	  is unnecessary and causes BADVcc conditions on many chipsets.  These
	  in turn can cause an interrupt storm.
	o Make pcic_disable reset the slot's voltage.
	o Move initializing voltage for the slot until after it has been
	  disabled.
	o Fix a lot of issues with the pcic_cardbus_power routine.  We
	  now properly enable the card and take it out of reset after
	  a power change.
	o When detecting the card's voltage, if we're in a BadVcc state,
	  direct the bridge to rescan the card for what it supports.
	  (we might need to in the future set the power register to 0
	   before doing this).
	o Don't preserve CLKSTOP.  need to revisit this.
	o Better support for Ricoh ISA bridges for 3.3V cards.
	o Don't write to PCIC_POWER directly as offten, but instead go
	  through the pcic_power interface.
	o All cardbus bridges now default to use cardbus power control.
	o Add misc register definitions.
	o remove some (now) bogus comments.

Extra Special Thanks To: Scott Lamber for his kind and generous loan
of a Toshiba laptop with a ToPIC 100 in it for my use.

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).

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

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.

- 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_*

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)

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.
