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.

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.

Again, ipppd has one kernel connection per channel in a MPPP
setting, so we should keep track in isdn_net_dev.

Dialing happens per channel / isdn_net_dev, so the move the
corresponding members there.

This is the first step of a long series moving members between
isdn_net_local and isdn_net_dev.

Today, a one-to-one relationship between these both structures exist, so
it does not really matter where the members live. However, the goal
is to get a correspondence like

net_device -> isdn_net_local -> master isdn_net_device
                                           |
                                slave  isdn_net_device
                                           |
                                slave  isdn_net_device

where more than one isdn_net_device can exist per actual net_device,
due to channel bundling.

GCC currently warns when page-flags.h gets included before struct page
is declared. Declare it.

X25 needs notification if an interface is brought up or down, and
ethernet over ISDN creates a fake MAC address at open time, so put this
into appropriate callbacks as well.

The ->init() callback can be used for calling ether_setup() in case
of encapsulation "ISDN over ethernet", for the other cases it does not
make sense anyway.
