Arjan van de Ven 4b7a89a3c1 [PATCH] pcmcia: fix deadlock in pcmcia_parse_events
The PCMCIA layer calls pcmcia_parse_events both from user context and
IRQ context; the lock thus needs to be irqsave to avoid deadlocks

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

this fixes a hang of rmmod in the sequence modprobe yenta_socket; rmmod
yenta_socket as reported by Andreas Steinmetz.  w/o this rmmod yenta_socket
can hang on wait_for_completion() in pcmcia_unregister_socket()

Christoph Lameter 3e1d1d28d9 [PATCH] Cleanup patch for process freezing
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!

Daniel Ritz fa912bcb06 [PATCH] yenta TI: turn off interrupts during card power-on #2
- 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())

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
