The patch below removes #if'd kernel 2.0 code from
drivers/isdn/divert/divert_init.c.

From: Christian Borntraeger <linux@borntraeger.net>
  
This patch makes isdn_tty HZ aware.
The first change changes 3000 jiffies (now 3 seconds) to 30 seconds according to
the comment.
I dont know, if the second change (schedule_timeout(50);) has to be half a
second but this was the value used in 2.4.

Instead of having "switch (subtype)" in just about every function,
rather use separate functions and invoke the right one using
the now existing struct card_ops infrastructure.

All IRQ handlers for IPAC based cards were basically the same (not
a big surprise, since the chip is the same), so we can share
the IRQ handler.

IPAC is basically a combined HSCX/ISAC chip, so we can generate
the D- and B-channel access functions knowing how to access the IPAC.
  
For performance reasons, this happens in a macro.

Just renaming and introducing some helpers makes them look very similar
to each other..

Except for a minor performance penalty, using the same IRQ handler
for cards which used the same code anyway seems perfectly natural...

Again, just killing some duplicated code.

Same change which happened for the B-channel earlier.

This mostly finishes splitting up the multiplexing ->cardmsg.

Since we now have a per-card ops struct, use it to provide the
irq handler function, too.

Some drivers actually drive more than one specific hardware card,
instead of having "switch (cs->subtyp)" scattered around, we rather
aim at having different card_ops structures which just provide the
right functions for the hardware. Of course, this patch is only the
beginning of that separation, but allows for some cleaning already.

Linux normally uses separate callbacks instead of a multiplexing
function like "cardmsg". So start to break that into pieces.

This is needed by some includers of <asm/stat.h>.

Implementing hash_str as hash_mem(..., strlen()) is actually quite slow,
so create a separate hash_str.

Now hash_mem has only one call site, and both are quite small, so we make them
both inline.

blk_plug_device and blk_remove_plug want irqs_disabled,
so we give it to them.

I think this is finally right:
 - we always wake_up when curr_resync decreases.
 - we wait for the other guys curr_resync to be less than ours
 - if we ever wait for someone who might yield, we start checking
   again from the start.

Currently nfsd only worries about read-only exports for
directories and files, which allows device special files
to be chmodded (for example).

This patch extends the test to cover all files, but is careful
to avoid it when an IRIX client is doing an write-permission test
against a pre-existing device special file.

We encode that status in the return value.

Also, don't pass 'proc' parameter to ->accept, as it is
implicit in rqstp.

If one of the callback (e.g. data ready) is called
before socket setup is complete, oops may occur.

With this patch, socket is kept SK_BUSY until all is
ready to avoid this.

Also some code is moved around to make it cleaner.
