.. 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]

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.

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.

All arguments except the name are unused - remove them and make the
name printf-like to avoid a few snprintf in the surrounding code.

(also fixes compilation to due a superflous endif in dvb core)

Needed to get the only callder of devfs_mk_dir where the first argument
is not NULL back in shape.  Also a nice code cleanup..

Sorry about that Linus.
