More ->get_sb() patches: pipefs

More ->get_sb() patches: fix for usbdevfs - forgot to remove
DECLARE_FSTYPE() after adding explicit initializer.

shmem/tmpfs switched

On my 512MB machine with 6 mount points the mount hash table uses 64K.
This patch brings it to a more reasonable size by limiting it to one
page.

Several file systems in tree that nominally support files >2GB set their
s_maxbytes value to ~0ULL. This has the nasty side effect on 32bit machines
that when a file write reaches the page cache limit (e.g. 2^43) it'll silently
wrap and destroy data at the beginning of the file.

This patch changes the file systems in question to fill in a proper limit.

I also have an alternate patch that adds a check for this generically
in super.c, but preliminary comments from Al suggested that he prefered
to do it in the file systems, so it is done this way way.

The default for NR_FILES of 8192 is far too low for many workloads. This
patch does dynamic sizing for it instead. It assumes file+inode+dentry
are roughly 1K and will use upto 10% of the memory for it.

Also removes two obsolete prototypes.

This patch speeds the bootmem freeing up a bit. Not particularly important,
but helps on some slow simulators where the loop can chew up significant
CPU time.

Hallo Linus,

This is the slab name cleanup you originally requested when the reiserfs
slab name too long boot bug was introduced. It replaces the static
name limit for slab cache names with the requirement for the caller
to supply a stable name. This version addresses all concerns that were given
over earlier versions of the patch.

As I do not feel very strongly about the slab cache name limit and you
also do not seem to be interested in it and the original bug of reiserfs
not booting anymore has been long fixed in your tree with the patch
you originally rejected from me I will not resend this patch after this
try.

Patch against 2.5.4pre1.

Now that all FS_SINGLE filesystems are using ->get_sb(), FS_SINGLE
can die.

devfs converted.

driverfs converted.

pcihpfs converted.

devpts converted.

Fix for idiotic typo in __get_sb_single().

converted fs/block_dev.c ("bdev") to ->get_sb.  use get_sb_nodev() as
helper. 

converted ramfs/rootfs to ->get_sb().  Use get_sb_nodev() as helper. 

converte usb to ->get_sb()

converte binfmt_misc to ->get_sb()

convert procfs to ->get_sb().  Similar to ext2, except that we use
get_sb_single() instead of get_sb_bdev().  Notice the we _don't_ keep
FS_SINGLE in flags - as the matter of fact, with ->get_sb() FS_SINGLE is
useless. 

ext2 switched to ->get_sb().  For that we had
        a) turned ext2_read_super() into ext2_fill_super() (instead of
"return NULL if failed and sb if succeeded" it's "return error value or
0").
        b) added ext2_get_sb(type, flags, dev, data) - all it does is
return get_sb_bdev(type, flags, dev, data, ext2_fill_super);
        c) replaced DECLARE_...() with explicit initializer.
That's it.

get_sb_bdev() et.al. get a new argument (fill_super) and become
exported.

	OK, here comes the long-promised switchover to ->get_sb().

New method added - ->get_sb(type, flags, dev, data).  At this point we
still keep ->read_super(), but it will go away in the end of series. 
->get_sb() is a generalization of get_sb_{bdev,nodev,single}() - as the
matter of fact, these will become common helpers used by filesystems in
their ->get_sb().

Patch done by Oliver Neukum.

Some driver changes were done by Oliver Neukum and David Brownell.

These changes have been approved by the CRIS maintainer.

	- add mem_flags support
	- portions of this patch by Oliver Neukum and David Brownell.

	- initial add of the "int mem_flags" call to the usb_submit_urb() call

  	- Updates the documentation
  	- Adds Veo Stingray support
  	- Fixes hotplug table dependency upon now-defunct symbol
  	- deletes drivers/usb/ibmcam.h

  	- Code-Review from Oliver Neukum: remove SMP races.
  	- Added some wake_up calls after auerbuf_releasebuf to wake up tasks waiting
  	  for cp buffers.
  	- Change the module count handling to automatic (owner: THIS_MODULE).

  Al Viro: fix a typo (destory->destroy)

   This is hopefully last bugfix for a bug introduced by struct inode splitting.
   Because of setting i_flags to some value and then cleaning the i_flags
   contents later, on-disk items received wrong item version ob v3.6 filesystems

	Kudos to OGAWA Hirofumi for finding that one - gcc barfs on the
current code, trying to define an alias to external symbol.

	hpux_getdents() contains a years-old copy of code from fs/readdir.c.
Switched to use of vfs_readdir(), which does correct locking.
