This patch fixes the MODULE_DEVICE_TABLE problems, the correct code was
accidentally lost a few merges back.  It is from Daniel Ritz
<daniel.ritz@gmx.ch>, below is the original message.

hello adam, jaroslav, list

this patch does:
- rename struct pnp_card_id to pnp_card_device_id
- fix all references to it

this is needed for the MODULE_DEVICE_TABLE() macro to work with pnp_card's.
jaroslav did this a while ago (changeset 1.879.79.1), but adam undid it a bit
later (changeset 1.889.202.3). but why?

w/o the patch gcc dies when compiling als100.c with the message 'storage size
of __mod_pnp_card_device_table unknown' (this is from the macro).

any reasons why i should not send this to linus?
against 2.5.65-bk

This trivial patch adds a missing kfree, the leak occurs when 
pnp_activate_dev fails.

- Prevents calling the node_info call more than necessary in order to take
load off the pnpbios
- intregrates the proc registration code with the device scanning code
- adds human readable error messages instead of number codes
- other small cleanups

Moves probing code to a central location and matches when new cards are 
added instead of only when new drivers are added.

Still pretty ugly debug macro, but this at least
makes it do the right thing when used in if/else blocks

Fix from Joe Perches <joe@perches.com>

This patch adds selectable EdgeTriggered/LevelTriggered behaviour to
epoll.

It has been widely discussed on lkml about two weeks ago and everyone
very welcome the change.  It has been even more widely discussed through
private emails with application developers, that do not feel confortable
posting on lkml.  The great value of the patch is that selecting the LT
behaviour, applications using poll/select can be ported very easily to
epoll, making existing apps to benefit from epoll scalability with very
short ETA's.

The API remains the same with the addition of a EPOLLET event flag that
sets the LT/ET behaviour for that fd.

Many usb drivers use the usb_devfs_handle variable instead of just
adding the usb/ prefix directly to their devfs_register calls.  Fix
that and make usb_devfs_handle static and unexported.

.. by moving a bunch of devfs-related code from fs/partition/check.c
to fs/devfs/base.c.  Also has the nice sideffect of getting rid of
a bunch of ugly ifdefs.

[This is the new and improved, rediffed, applying and compilable
 version.  In short it's perfect]

From: Nikita Danilov, Maneesh Soni

d_lookup() is forgetting to release the lock when the rename race happens.

by having a cast followed by an initializer. It seems even gcc can't
do it right anyway in some versions (as reported by Jens Axboe).

+ C99 struct initialisers

Another brought forward from 2.4.

Spotted by Oleg Drokin

A proper PCI_DEVICE_ID... would have been nice,
but for now, this syncs with 2.4

It could be negative.

This is the other part of the missing bits of the compat_ptr patch
pointed out to me by Andrew Morton and Dave Miller. This is just
the architectures I have permission to send you.  Dave has sent you
his own already.

FYI, I have gotten some most strange results with the equivalent of:

     request_queue_t *q = kmalloc(...);
     blk_init_queue(q, ...)

The problem turns out to be that q->backing_dev_info.memory_backed is not
initialized, leaving it to be whatever was there before.  The end result is
that my "driver" never saw write requests, but reads came through fine.
Took a while to figure out that one...

Here's the fix, for what it's worth.  (I had, BTW, tried just zeroing the
whole structure in blk_init_queue(), but that makes IDE oops at boot - it
sets q->queuedata early).

This is a pure identity cleanup:

 - coding style fixes (whitespace, code, comment, line length cleanups)
 - remove dead code
 - simplify constructs, make code more readable

asm-generic/tlb.h needs swap.h for free_page_and_swap_cache().

Avoid a bunch of non-NULL first arguments.
