[RFC v4] PCMCIA locking updates for 2.6.34

[Dominik Brodowski]

Hey,

The v4 of the locking pathes are available in the git repository -- along
with a few other fixes and improvements -- at:

    git://git.kernel.org/pub/scm/linux/kernel/git/brodo/pcmcia-2.6.git#locking

Only those patches which changed (and which are marked with * below) will be
sent out to the PCMCIA list. Changes since v3:

- avoid prod_id memleak
- use pccardd for any requery work, not the workqueue

Best,
	Dominik

      pcmcia: properly lock skt->irq, skt->irq_mask
      pcmcia: protect s->device_count
      pcmcia: add locking to struct pcmcia_socket->pcmcia_state()
      pcmcia: simplify locking
      pcmcia: add locking documentation
      pcmcia: assert locking to struct pcmcia_device
      pcmcia: use mutex for dynid lock
      pcmcia: use ops_mutex for rsrc_{mgr,nonstatic} locking
      pcmcia: use pccardd to handle eject, insert, suspend and resume requests
    * pcmcia: delay re-scanning and re-querying of PCMCIA bus
    * pcmcia: use state machine for extended requery
      pcmcia: avoid sysfs-related lockup for cardbus
      pcmcia: disable pcmcia ioctl for !ARM
    * pcmcia: avoid prod_id memleak
