Leave the overloaded "hotplug" word to susbsystems which are handling
real devices. The driver core does not "plug" anything, it just exports
the state to userspace and generates events.

Print out minimal information in dmesg whnever a CardBus or PCMCIA card
is inserted into or ejected from a slot. This will make debugging certain
types of bugs much easier, and is similar to output produced by other
hotpluggable buses.

- thread_done should only be completed when the wait_queue is installed.

- all wake up conditions should be checked before schedule()

this fixes a hang of rmmod in the sequence modprobe yenta_socket; rmmod

If probing for the correct interrupt fails on yenta bridges, the driver falls
back to polling for interrupt actions.  However, CardBus cards cannot be used
then.

1. Establish a simple API for process freezing defined in linux/include/sched.h:

   frozen(process)		Check for frozen process
   freezing(process)		Check if a process is being frozen
   freeze(process)		Tell a process to freeze (go to refrigerator)
   thaw_process(process)	Restart process
   frozen_process(process)	Process is frozen now

2. Remove all references to PF_FREEZE and PF_FROZEN from all
   kernel sources except sched.h

3. Fix numerous locations where try_to_freeze is manually done by a driver

4. Remove the argument that is no longer necessary from two function calls.

5. Some whitespace cleanup

6. Clear potential race in refrigerator (provides an open window of PF_FREEZE
   cleared before setting PF_FROZEN, recalc_sigpending does not check
   PF_FROZEN).

This patch does not address the problem of freeze_processes() violating the rule
that a task may only modify its own flags by setting PF_FREEZE. This is not clean
in an SMP environment. freeze(process) is therefore not SMP safe!

- make boot-up card recognition more reliable (ie.  redo interrogation
  always if there is no valid 'card inserted' state) (and yes, i saw it
  happening on an o2micro controller that both CB_CBARD and CB_16BITCARD
  bits were set at the same time)

- also redo interrogation before probing the ISA interrupts.  it's safer
  to do the probing with the socket in a clean state.

- make card insert detect more reliable.  yenta_get_status() now returns
  SS_PENDING as long as the card is not completley inserted and one of the
  voltage bits is set.  also !CB_CBARD doesn't mean CB_16BITCARD.  there is
  CB_NOTACARD as well, so make an explicit check for CB_16BITCARD.

- for TI bridges: disable IRQs during power-on.  in all-serial and tied
  interrupt mode the interrupts are always disabled for single-slot
  controllers.  for two-slot contollers the disabling is only done when the
  other slot is empty.  to force disabling there is a new module parameter
  now: pwr_irqs_off=Y (which is a regression for working setups.  that's
  why it's an option, only use when required)

- modparm to disable ISA interrupt probing (isa_probe, defaults to on)

- remove unneeded code/cleanups (ie.  merge yenta_events() into
  yenta_interrupts())

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
