Add a function to set queue merge_bvec_fn to mimic the rest of the api,
and also add documentation for that and blk_queue_prep_rq().

The might_sleep() thing caught ide, which calls request_irq() with a
lock held. It can be argued that this is a bad thing, however I think it
can also validly be argued that requesting an irq should not be a
blocking operation. This might even remove some driver bugs where usage
count is not incremented during init...

It can also be argued, that the very first irq requests cannot be
blocking for io anyways, for good reason :-)

Too trivial to see the first time when debugging on weekends ;-))

This fixes a procfs crash noticed by Anton Blanchard.

The procfs code can have a reference even to an already exited task, so
it needs to follow special rules accessing p->sig.  The atomic-signals
patch made this bug happen at a much higher frequency, but procfs i
believe was buggy ever since, it potentially used the freed signal
structure - which just did not result in a crash like it does today.

The proper fix is to take the tasklist read-lock in
collect_sigign_sigcatch(), this excludes __exit_sighand() freeing the
signal structure prematurely.

due to synchronize_irq() becoming a no-op when !CONFIG_SMP.

uml.ld.S.

With this we avoid doing skb_clone on skbs that will not be kept on
unacked lists.

Thanks do Andries Brouwer for reporting the problem and suggesting a
way to fix it.

Thanks to Andries Brouwer for providing a patch.

Crud.  Looks like my patch making script was borken, so orinoco_pci.c
wasn't updated properly.  The patch below should fix that, and adds
some other minor updates (driver version 0.13a) as well.

Fix pci_pool_create() from calling device_create_file() under
pools_lock.

Found by the new "may_sleep" infrastructure.

Keeping track of dialing / auto hangup is per ISDN channel, so should
go into isdn_net_dev.
