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.

09-64bit_bitops_fix-1.diff
    Bitopts arguments must be long, not int.

08-unfinished_rebuildtree_message.diff
    Give a proper explanation if unfinished reiserfsck --rebuild-tree
    run on a fs was detected.

07-remove_nospace_warnings.diff

05-kernel-reiserfs_fs_h-offset_v2.diff
    Convert erroneous le64_to_cpu to cpu_to_le64

04-nfs_stale_inode_access.diff
    This is to fix a case where stale NFS handles are correctly detected as
    stale, but inodes assotiated with them are still valid and present in cache,
    hence there is no way to deal with files, these handles are attached to.
    Bug was found and explained by
    Anne Milicia <milicia@missioncriticallinux.com>

03-key_output_fix.diff
    Fix all the places where cpu key is attempted to be printed as ondisk key

02-prealloc_list_init.diff
    prealloc list was forgotten to be initialised.

01-pick_correct_key_version.diff
    This is to fix certain cases where items may get its keys to be interpreted
    wrong, or to be inserted into the tree in wrong order. This bug was only
    observed live on 2.5.3, though it is present in 2.4, too.

Remove struct iobus.

There is a lot of duplication between struct device and struct iobus, both
in their members and the code in their interfaces. Waxing struct iobus
removes this duplication and makes things a bit simpler.

Patch 4: Add some default files for PCI devices.

This adds two files for PCI devices: 'irq' and 'resources'. They display
just those things and currently do nothing on write. These are the
examples for other subsystems to use for creating files ('Hey, look how
simple it is!')

Patch 3: Make default callbacks simpler.

I want to move as much to a 1 file/1 value model as possible. I haven't
come up with a clean way to enforce it except via social pressure.

This patch is a step in that direction. It:

- Reduces the output of 'power' to just the decimal state of the device
- Adds a 'name' file which exports just the device name
- Reduces the 'status' file to just export the bus ID. (This will change,
  since the bus ID is obvious based on what directory you're in, but it's
  another patch at another time)

Patch 1: Make device_driver_init() an initcall.
It declares it as subsys_initcall and removes the explicit call from
init/main.c::do_basic_setup().

Here is a patch to enhance xconfig to read the new Config.help files.
Olaf Dietsche wrote this, and Steven Cole passed it on to me.

Testing: Steven Cole tested it, and I tested it.
