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.

	Yet another flag/wait_queue pair bites the dust - hfs bitmap_{lock,wait}
was trying to implement a semaphore.

	Useless (lock,waitqueue) pair killed - we have fs-wide
exclusion between renames enforced by VFS, so hfs rename_{lock,wait}
can be removed.

	Pair (flag, wait_queue) in hpfs replaced with semaphore.

The previous patch did not provide protection for device lseek methods
(drivers/* stuff).  This patch pushes the BKL into each of the remaining
lseek methods -- without them we have a race.

I'd much prefer to have a a better lock to push down than the BKL, but
that will have to wait.

Before you balk at the size, remember patch #2 in this series which
removed much code ;-)

Thanks to Al for assistance, especially a listing of affected files.

This is the second patch of three implementing further llseek cleanups,
against 2.5.4-pre1.  It does not depend on the other patches.

This patch cleans up various code and quite nicely removes much more
code than it adds.  Specifically:

- remove static lseek method which merely reimplements
  the standard no_llseek in the following seven files:
  hci_vhci.c, ite8172.c, nec_vrc5477.c, auerswald.c,
  pipe.c, netlink_dev.c, and socket.c

- remove fs/ufs/file.c::ufs_file_lseek -- Al says it is
  reimplementing generic_file_llseek, so let's use that
  instead (the comment about 32-bit sizes shouldn't be
  an issue, the generic method checks size)

- include smp_lock.h in 3 files missed from previous
  'remove bkl' patch

- Documentation/filesystem/Locking update

Please, apply.

This is the first of three patches implementing further llseek cleanup,
against 2.5.4-pre1.

The 'push locking into llseek methods' patch was integrated into 2.5.3.
The networking filesystems, however, do not protect i_size and can not
rely on the inode semaphore used in generic_file_llseek.

This patch implements a remote_llseek method, which is basically the
pre-2.5.3 version of generic_file_llseek.  Locking is done via the BKL.
When we have a saner locking system in place, we can push it into this
function in lieu.

Ncpfs, nfs, and smbfs have been converted to use this new llseek.

Note this is updated over the previous posted patch.

ia64: switched from sys_new*stat() to vfs_*stat() and cleaned up. 

solaris: switched from sys_new*stat() to vfs_*stat() and cleaned up. 
Missing LFS check added. 

irix_...() switched from sys_new*stat() to vfs_*stat() and cleaned up. 
Missing LFS check added

stat(2) variants in arch/* that used to copy inode fields manually
switched to vfs_*stat() and partially cleaned up

	added new helpers - vfs_stat(), vfs_lstat() and vfs_fstat().
	fs/stat.c switched to use them.

Following patches will

	stat(2) variants in arch/* that used to copy inode fields manually

	irix_...() switched from sys_new*stat() to vfs_*stat() and cleaned

	similar for solaris ones

	ditto for x86 compatibility ones on ia64.

We are almost ready to switch to ->getattr() - let filesystem decide what
values should go into ->st_... (e.g. for CODA life would become much
easier if it could just use ->i_size of caching file, for supermount
we want ->i_ino inherited from underlying fs, etc.)

Another thing that needs to be done is fixing the rest of LFS/uid size
fsckups in architecture-specific variants of stat() - I've fixed several,
but quite a few are still there.

	procfs switched to alloc_inode/destroy_inode.

	more inode->u trimming - socket_i is killed.

During the course of developing our pthread library (the NGPT pthread
library) it became clear we needed some kernel support for handling
signals.  This patch helps the library by redirecting all signals sent
to tasks in a thread group to the thread group leader.  It also defines
the tkill() system call so the library can signal a specific task if
necessary. 

Given that as far as I know NGPT is the only user of thread groups, and
that this change would benefit any other user of thread groups, I'm
submitting this for inclusion in the 2.5 kernel.

Note that this patch also adds support for sys_gettid() for the
architectures that don't have it.  While this could have been split into a
spearate patch, it would create conflicts since this patch also adds
sys_tkill(), so I felt it was cleaner to leave them together.

The patch moves:

	* joystick drivers from drivers/char/joystick to drivers/input/joystick
	* gameport drivers from drivers/char/joystick to drivers/input/gameport
	* serio drivers from drivers/char/joystick to drivers/input/serio

I don't think the joystick drivers should stay in char, because they're
NOT character device drivers (check for register_chrdev, none to be found).

It also fixes build problems with sound driver gameport support.

the appended patch works around a bug in the PLX9050 chip. This chip is
used in various PCI ISDN adapters (it's an PCI interface chip) and has
an erratum when the BAR 0/1 has bit 7 set (the size of the region is
0x80, so aligning it to 0x80 is legal and really happens for people).

This workaround has been tested by a user who hit this problem with a
Gazel card. Basically the same fix has been done for Elsa cards, but it's
untested.

the appended patch fixes a problem where the ->rcvidx variable was not
initialized properly.

the appended patch fixes a case of undefined behavior, found by
Urs Thuermann and "VDA".

the appended patch by Igmar Palsenberg fixes the CHARGE_HUP functionality
(automatically hang up just before the next charging unit)

the appended patch by Adrian Bunk removes yet another leftover from
the /dev/isdnX devices (which causes an build error when
CONFIG_DEVFS_FS=y).

 Correct typo in Documentation/Changes.
 Remove duplicate code in arch/i386/boot/bootsect.S.

  I've found that multiple level initcalls went into kernel
behind my back, so you can throw away my yesterday patch
which converted lib.a => lib.o, and apply this one.

[Patch tested with both lib.a and lib.o - it boots correctly
in both cases]

Linus, this reverts limit for request size from 10KB to unlimited.
Although no released nbd version supports it, it is certainly better to
add support to servers than cripple clients if incompatibility does
not matter.

Following a request by David Chow on linux fsdevel, this patch causes
NFS read and write requests to take the inode from page->mapping->host
rather than relying on file->f_dentry->d_inode. Apparently this will
simplify some work he is doing on another filesystem.

In any case, it cleans up the current mix of sometimes doing one
thing, sometimes the other (historical cruft), and puts NFS client
behaviour on par with what is done in other filesystems...

  The following patch should fix a problem of ETXTBSY sometimes
occurring if one tries to run a file straight after compilation.

The problem is that both NFS read and write requests can currently
hold a count on the struct file. This is done partly so as to be able
to pass along the RPC credential (which is cached in the struct file),
and partly so that asynchronous writes can report any errors via the
file->f_error mechanism.

The problem is that both the read and write requests may persist even
after file close() occurs. For O_RDONLY files, this is not a problem,
but for O_WRONLY, and O_RDWR files, the fact that the struct file is
not released until the last call to nfs_release_request() means that
inode->i_writecount does not necessarily get cleared upon file
close().

The following patch fixes both these issues.

  - NFS read requests no longer hold the struct file. They take a
    count on the the RPC credential itself.

  - NFS write requests still hold the struct file, since they want to
    report errors to sys_close() using the file->f_error mechanism.
    However they are made to release the page, credential, and file
    structures as soon as the write is completed instead of following
    the current practice of waiting for the last nfs_page request
    release.

  This is a resend of the NFS lookup code rewrite, but with the open(".")
VFS fix removed. (I'll resend the 'uses d_revalidate()' version
separately after a suitable delay to allow for comments.)

  Issues fixed by this patch:

 - Use the directory mtime in order to give us a hint when we should
   check for namespace changes.

 - Add support for the 'nocto' flag, in order to turn off the strict
   attribute cache revalidation on file open().

 - Simplify inode lookup. Don't check the 'fsid' field (which appears
   to be buggy in too many servers in order to be reliable). Instead
   we only rely on the inode number (a.k.a. 'fileid') and the
   (supposedly unique) filehandle.
