- Remove some 2.4 compatibility macros
- Fix userspace pointer misuse in video1394 ioctl. Caught by the
  Stanford Checker. Gotta love the automated systems.
- Move our hotplug stuff around, to make the transition to putting our
  module dev table in mod_devicetable.h.
- Fix ohci1394 for possible crash with async stream packets. Cleaned up
  some debug messages.

This fixes two bugs introduced by some 2.5 changes:

- O_NDELAY handling typo in floppy_open()

- handling of failed transfers in floppy_end_request()
  (do equivalent of what 2.4 does)

Without first fix I was getting "floppy0: disk absent or changed during
operation" infinite loop on opening and without second fix, infinite loop
on error retry.

Now floppy driver seems to be (somehow) working :-).

This file was _the_ header for block-device related stuff in earlier
Linux versions, but nowdays there's just a few prototypes left that
really belong into blkdev.h or genhd.h (and in one case elevator.h).

This patch moves them over and removes everything but including
blkdev.h from blk.h  Note that blkdev.h gets all the headers that
were included in blk.h inmplicitly too.  Now we can start removing
all references to it an maybe kill it off before 2.6.  *sniff*

This adds ieee1394 for module table registration.

This fixes the compat_ioctl interface for the case where a NULL handler
is registered. This should produce a "compatible" as opposed to
"translated" interface for the specified ioctl. The patch was sent to
linux-kernel and no one complained (atleast with this second rev).

Currently __bdevname walks the obsolete list of block majors to
find a name for the given dev_t and falls back to unknown-block(%u,%u)
if that's not possible.  Replace this with an attempted get_gendisk() +
disk_name.  This means __bdevname can't be called from irq context
anymore, but as all old irq context callers are using bdevname() now
that fine (and I've added a big comment).

 - both rpciod_up and rpciod_down do a gratious inc/dec of the
   use count - but we can't ever be inside those function unless
   it's called from an other module -> totally useless
 - rpciod() (the kernel thread) also bumps the refcount when starting
   and decrements it when exiting.  but as a different module must
   initiate this using rpciod_up/rpciod_down this is again not needed.
   (except when a module does rpciod_up without a matching rpciod_down -
   but that a big bug anyway and we don't need to partially handle that
   using module refcounts).

Add unwind info for sigreturn entry points.

This allows access to the globally shared FIXMAP mapping for ptrace
and frieds, so that debuggers can sanely trace through the vsyscall
sequence.

Schedule work away on an unmap, instead of calling it directly. Should result
in less lost samples, and it fixes a lock ordering problem buffer_sem <-> mmap_sem

Change the lost_mmap_sem stat to lost_no_mm, and account it.

We were doing del_timer_sync() on shutdown, but not ensuring that any queued work
was done as well.

Now we don't do buffer syncs whilst holding current's mmap_sem ever,
we can wait to hold it. Also take task_lock and try to improve the docs a bit.

If there's are multiple tasks sleeping inside the read routine ever, this is necessary.

Clear up the code around  start_sem so it's more obvious, and remove a pointless
down/up pair on buffer_sem (shutdown is already synchronised in sync_stop()).

Consolidate all the arch copies of timer_int.c into one place. Also fixes
a problem with PA-RISC not using instruction_pointer() when it should.

Convention is that error returns are negative.

This patch adds new PCI IDs to the drivers/pci/pci.ids file.
