cf0ee54fec - Fix a bug where a "power_off_slot' timeout was not cancelled when the
computer 'suspended', although the slot was powered off.  There was a
  race where the slow could be powered off *after* it was assigned a
  new driver when the computer was 'resumed'.

9a2daf9190 Changed the type of an isa/general interrupt handler to take a
`void *' arg.  Fixed or hid most of the resulting type mismatches.
Handlers can now be updated locally (except for reworking their
global declarations in isa_device.h).

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.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

480895cbea - Give up trying for a simple solution for correctly recognizing if a card
was really removed, or simply 'faked' by a suspend/resume.  Keep track
  of both current and previous state, and send that information to the
  userland programs.

40b8c3d008 MF22:
(update_intr_masks might not need to be done in 3.X, but the new generic
 interrupt code is incomplete w/regard to support for the PCCARD code, so
 to avoid any potential problems use it.  It can't hurt).

- Correctly register pcic_imask with the system interrupt code.

- Call update_intr_masks() so that pcic_imask modifications that occur
  when card interrupts are registered get updated in the system
  interrupt code.

ec510cabb0 - Disable cards when doing a suspend by emulating that they have been
removed.  Add a new state 'suspend' so we 'fake' insertion events at
  resume time for the cards that have been suspended.

[
The code still works if you remove the card during suspend, switch the
card during suspend, or combinations of both.

075a76a29e - Instead of relying on a functional call to register PCARD-capable drivers,
use a Linker Set.  Note, if a driver is loaded as an LKM  if will have
  to use the function call, but since none of the existing drivers
  are loadable, this made things cleaner and boot messages nicer.

8bb7a8fc95 - Functional changes to PCCARD support.
* Kill individual drivers 'suspend' routines, since there's no simple/safe
   way to suspend/resume a card w/out going through the complete probe
   at initialization time.
 * Default to using the apm_pccard_resume sysctl code, which basically
   pretends the card was removed, and then re-inserted.  Suspend/resume
   is now 'emulated' with a fake insert/removal.  (Hence we no longer
   need the driver-specific suspend routines.)

   naming schemes.

2e6bafc0a2 - When doing suspend/resume, only try to suspend those drivers on active
slots.  Otherwise, we try to suspend drivers who have been disabled
  already.

[
The only reason the drivers are still on the list is because of race
conditions where the card is removed while the driver is in use.  We
leave the drivers on the slot list (leaving all of their structures in
place in case a process is using it) but set it's state to empty so that
further uses by the pccard code know not to expect active cards.

cc6da87199 Update the PCIC controller's imask with individual slot IRQ's.
Assuming that the intr_mask[] was updated by changing the maskptrs (the
existing update_intr_masks() function will not work) this code was
written so the PCIC controller insertion/removal events will not
interrupt the card IRQ handler events.

Some possible scenarios:
+ Card is removed during IRQ handler:

  - PCIC card handler is allowed to interrupt
  - card removal event is called, removing the driver and data structures
  * card interrupt handler continues w/out driver, data structures, and hardware

OR (the code just committed)

  * card IRQ handler has no hardware to read/write to, but has code and
    data to run on (XXX- Assume it completes and doesn't spin forever)
  - PCIC card handler unloads the card driver

The current situation at least leaves the card interrupt handlers the
drivers and data structures to work with although the hardware can't be
guaranteed.
