As a step in the process of updating all the linux input drivers to the
most recent version available, this patch updates all the joystick
drivers that are in the kernel tree.

Changes are mainly the input hotplug/proc support in every of the
joystick drivers, and fixing trivial bugs here and there. I can supply a
more detailed description upon request.

This fix is from Dave Bogdanoff <bog@transmeta.com>.

Linux incorrectly sets up IDE timings for secondary slave drives on PC
systems that use Intel PIIX Southbridges.

This will correctly shift IDE slave PCI timings for register 44h so
that:

 - secondary slave (drive1) uses bits 4-7
 - primary slave   (drive1) uses bits 0-3

(The addition of the parentheses is needed so the shift will take
place after the bitwise-or.  Without the parentheses, the shift will
incorrectly always take place before the bitwise-or.)

x86_64 does not have an irq_stat array. It puts the interrupt information
into its per CPU area instead, allowing more efficient access to it.
This patch allows the architecture to overwrite
the __IRQ_STAT access macro in linux/irq_cpustat.h.

It is required to make the x86_64 port compile.

-Andi

This patch makes x86-64 compile in 2.5.5 and syncs it with changes in the i386
port. It also fixes some bugs that were discovered in recent testing:
- enhance 32bit emulation and fix bugs.
- fix security hole in vmalloc handling
- Do not use lockless gettimeofday for now because it is buggy.
The patch only changes x86_64 specific files.

- added support for KERN_ prefixes for snd_printk
- verbose printk (file:number) is now optional
- fixed devfs OSS device names in soundcore
- added XRUN ioctl for PCM API
- improved support for Sound Blaster Audigy
- fixed AC3 forwarding for Sound Blaster Live!
- more fixes in dependencies in Makefiles
- llseek locking fixes for sound/core/info.c
- fixed ISA DMA allocation
- added wait() callback for ac97_codec.c and VIA686 driver
- CMIPCI driver updates
- added AMD-8111 support for Intel8x0

This patch to allow using of RTC timer inside the kernel space.  We can
use the RTC timer as timing source for ALSA sequencer. Patch by Takashi.

The patch adds these three functions and one structure to rtc.h and
rtc.c:

typedef struct rtc_task {
       void (*func)(void *private_data);
       void *private_data;
} rtc_task_t;

int rtc_register(rtc_task_t *task);
int rtc_unregister(rtc_task_t *task);
int rtc_control(rtc_task_t *t, unsigned int cmd, unsigned long arg);

This moves the dmi scan to an earlier stage so that we can trap issues
such as the various laptops that don't like enabling APIC.
It's likely to be useful for trapping other similar early-boot problems.

Linus,
 Current driver in your tree has been 'fixed' by someone without
understanding just how broken it was. Numerous fixes were done in 2.4
after the 2.5 split by Alan.

This patch reverts the damage the driver does in your tree, and brings
Alan's 2.4 bits over instead. Downside: It doesn't compile.
Upside: It doesn't pretend to work and corrupt data, and at least
is the right base for people to start fixing.

Updated maintainers list from Ingo's last ping,
various changed email addresses in code headers.

From 2.4.17

First batch of various kdev_t related changes that have accumulated on
linux-kernel, and some that got sent directly to me after you dropped them.

Some of these need additional fixes to make them work, Some of them
even to make them compile, but this is one step forward..

I have bio-related fixes for some of these also, I'll push those seperately.

OK, here's ->d_parent stuff unrelated to printk.  Looking into printk
right now...

Protect d_parent with "dparent_lock", making ready to get rid of
BKL for d_move().

[Alan: also applies to 2.2.x]

William Stearns: linux/fs/file.c comment fix

	Patch below does the following:

*	removes dead code from wanproc.c.   When file looks like
#ifdef LINUX_2_4
<800 lines>
#else
<900 lines>
#endif
	there's no excuse for keeping all that junk around.
*	switches wanproc.c to use of seq_file
*	removes dead code from wanmain.c (again, dead == never seen by cc1).
*	fixes indentation in both
*	removes buttloads of trailing spaces in these files, while we are
	at it.

See if it's OK with you...

Preparation to adding new method:
 new helper - shutdown_super().  It is cut from kill_super() and
 it had absorbed all actions done with superblock contents -
 now kill_super(s) is simply

	struct file_system_type *fs = s->s_type;
	if (!deactivate_super(s))
		return;
		shutdown_super(s);
	put_filesystem(fs);

 and shutdown_super() is going to become a method.

Now remove_super() is called only from kill_super().  We move
the code that closes device/drops reference to filesystem type
from remove_super() into its caller.

* missing yield() added to grab_super() (on failure exit).  Without
  that we have a nasty race - if get_sb_bdev() happens just before
  we grab ->s_umount in kill_super(), we are going to have
  get_sb_bdev() spinning indefinitely long without yielding CPU,
  so that kill_super() could make progress (and break the loop).

* in kill_super() code that does actual superblock shutdown is
  wrapped in if (sb->s_root) {}.  That condition is true for
  all old callers of kill_super(), so we don't change existing
  behaviour.

* instances of deactivate_super()/remove_super() (after failed
  call of foo_fill_super()) are replaced with
	up_write(&s->s_umount);
	kill_super(s);
  - now it becomes legitimate (kill_super() works on such guys and
  does exactly what we want).

here's much simpler fix (both 2.4 and 2.5):

- cleanup patch from Hugh Dickins, fix up drivers to use vmalloc_to_page() instead of local hacks of uvirt_to_kva(). (and related fixes.)

- new, less intrusive and faster migration method:

/*
 * This is how migration works:
 *
 * 1) we queue a migration_req_t structure in the source CPU's
 *    runqueue and wake up that CPU's migration thread.
 * 2) we down() the locked semaphore => thread blocks.
 * 3) migration thread wakes up (implicitly it forces the migrated
 *    thread off the CPU)
 * 4) it gets the migration request and checks whether the migrated
 *    task is still in the wrong runqueue.
 * 5) if it's in the wrong runqueue then the migration thread removes
 *    it and puts it into the right queue.
 * 6) migration thread up()s the semaphore.
 * 7) we wake up and the migration is done.

the lvm-patch that went into 2.5.5 missed the changes in lvm.h and is
still not compileable. This patch adds those changes. The kernel i'm
running right now has this patch and /var and /home on lvm.

A forward-port of all the .text.exit fixes which went into
2.4.   Also contains a couple of s/MINOR/minor/ changes.

Al updated Documentation/filesystems/porting with 2.5 changes but there
is no mention of lseek.  The following patch, against 2.5.5, adds lseek
to the list of functions that no longer are called with the BKL.
