Subject: [WATCHDOG] correct sysfs name for watchdog devices

While looking for possible candidates for our udev.rules package,
I found a few odd ->name properties. /dev/watchdog has minor 130
according to devices.txt. Since all watchdog drivers use the
misc_register() call, they will end up in /sys/class/misc/$foo.
udev may create the /dev/watchdog node if the driver is loaded.
I dont have such a device, so I cant test it.
The drivers below provide names with spaces and even with / in it.
Not a big deal, but apps may expect /dev/watchdog.

Subject: [WATCHDOG] s3c2410 watchdog power management

Patch from Dimitry Andric <dimitry.andric@tomtom.com>, updated
by Ben Dooks <ben-linux@fluff.org>. Patch is against 2.6.11-mm2

Add power management support to the s3c2410 watchdog, so that
it is shut-down over suspend, and re-initialised on resume.

Also add Dimitry to the list of authors.

Subject: [WATCHDOG] w83627hf_wdt.c-initialized_bios_bug

Attached is a small update to the w83627hf watchdog driver
to initialise appropriately if it was already initialised
in the BIOS. On tyan motherboards for e.g. you can init
the watchdog to 4 mins, then when the driver is loaded it
sets the watchdog to "seconds" mode, and then machine will
reboot within 4 seconds. So this patch resets the timeout
to the configured value if the watchdog is already running.

Subject: [WATCHDOG] softdog-timer-running-oops.patch

The softdog watchdog timer has a bug that can create an oops:

1.  Load the module without the nowayout option.
2.  Open the driver and close it without writing 'V' before close.
3.  Unload the module.  The timer will continue to run...
4.  Oops happens when timer fires.

Reported Sun, 10 Oct 2004, by Michael Schierl <schierlm@gmx.de>

Fix is easy: always take a reference on the module on open.
Release it only when the device is closed and no timer is running.
Tested on 2.6.13-rc6 using the soft_noboot option.  While the
timer is running and the device is closed, the module use count
stays at 1.  After the timer fires, it drops to 0.  Repeatedly
opening and closing the driver caused no problems.  Please apply.

Subject: [SERIAL] Fix moxa tty driver name

The moxa driver was named "ttya", which is wrong:
1) Documentation/devices.txt says that the name should be "ttyMX".
2) First 10 ports (ttya0...ttya9) clash with the legacy pty driver.

This patch changes the driver name to "ttyMX".

Subject: [PATCH] tpm_infineon: Bugfix in PNPACPI-handling

This patch corrects the PNP-handling inside the tpm-driver
and some minor coding style bugs.
Note: the pci-device and pnp-device mixture is currently necessary,
since the used "tpm"-interface requires a pci-dev in order to register
the driver. This will be fixed within the next iterations.

Subject: [PATCH] ppc32: Added support for the Book-E style Watchdog Timer

PowerPC 40x and Book-E processors support a watchdog timer at the processor
core level.  The timer has implementation dependent timeout frequencies
that can be configured by software.

One the first Watchdog timeout we get a critical exception.  It is left to
board specific code to determine what should happen at this point.  If
nothing is done and another timeout period expires the processor may
attempt to reset the machine.

Command line parameters:
  wdt=0 : disable watchdog (default)
  wdt=1 : enable watchdog

  wdt_period=N : N sets the value of the Watchdog Timer Period.

  The Watchdog Timer Period meaning is implementation specific. Check
  User Manual for the processor for more details.

This patch is based off of work done by Takeharu Kato.

Subject: drm: fix issue with handle lookup for a 0 handle

On 32-bit PPC a 0 handle is valid for AGP space, the 32/64 lookup
doesn't handle 0 correctly.

Subject: drm: small cleanups

This patch contains the following small cleanups:
- make two needlessly global functions static
- drm_sysfs.c: every file should #include the header with the prototypes
              of the global functions it is offering

Subject: [MOXA]: Fix this driver properly.

Actually, proper fix of that breakage is embarrassingly simple - it's yet
another gratitious leftover include of asm/segment.h, so incremental to the
previos would be removal of that BROKEN and removal of bogus include from
mxser.c itself.

Subject: [SPARC64]: Kconfig fix (GEN_RTC dependencies)

Yet another architecture not coverd by GEN_RTC - sparc64 never picked
it until now and it doesn't have asm/rtc.h to go with it, so it
wouldn't compile anyway (or have these ioctls in the user-visible
headers, for that matter).

FWIW, I'm very tempted to introduce ARCH_HAS_GEN_RTC and have it set
in arch/*/Kconfig for architectures that know what to do with this
stuff - for something supposedly generic the list of architectures
where it doesn't work is getting too long...

Subject: [PATCH] sonypi SPIC initialisation fix

Newer Sony VAIO models (VGN-S480, VGN-S460, VGN-S3XP etc) use a new method to
initialize the SPIC device.  The new way to initialize (and disable) the
device comes directly from the AML code in the _CRS, _SRS and _DIS methods
from the DSDT table.  This patch adds support for the new models.

Subject: [PATCH] Console blanking locking fix

I've had WARN_CONSOLE_UNLOCKED warnings when calling TIOCLINUX
TIOCL_BLANKSCREEN and TIOCL_UNBLANKSCREEN.

(I'm blind and I use a braille display.  I use those functions to blank my
laptop's screen so people don't read it, and hopefully to conserve power.)

The warnings are from these places:
do_blank_screen at drivers/char/vt.c:2754 (Not tainted)
save_screen at drivers/char/vt.c:575 (Not tainted)
do_unblank_screen at drivers/char/vt.c:2822 (Not tainted)
set_palette at drivers/char/vt.c:2908 (Not tainted)

At a glance I would think the following patch ought to fix that.  Tested on
one machine.  Could you please tell me if this is correct and/or forward
the patch where appropriate...

Subject: [PATCH] vt: fix possible memory corruption in complement_pos

Based on a patch from Andr Pereira de Almeida <andre@cachola.com.br>

It might be possible for the saved pointer (*p) to become invalid in
between vc_resizes, so saving the screen offset instead of the screen
pointer is saner.

This bug is very hard to trigger though, but Andre probably did, if he's
submitting this patch.  Anyway, with Andre's patch, it's still possible for
the offsets to be still illegal, if the new screen size is smaller than the
old one.  So I've also added checks if the offsets are still within the
screenbuffer size.

Subject: [PATCH] ipmi: add per-channel IPMB addresses

IPMI allows multiple IPMB channels on a single interface, and each channel
might have a different IPMB address.  However, the driver has only one IPMB
address that it uses for everything.  This patch adds new IOCTLS and a new
internal interface for setting per-channel IPMB addresses and LUNs.  New
systems are coming out with support for multiple IPMB channels, and they are
broken without this patch.

Subject: [PATCH] ipmi: OEM flag handling and hacks for some Dell machines

The ipmi driver does not have a way to handle firmware-generated events
which have the OEM[012] Data Available flags set.  In such a case, the
SMS_ATN bit may never get cleared by firmware, leaving the driver looping
infinitely but never able to make any progress.

This patch first simplifies storage and use of the data returned from an
IPMI Get Device ID command.

It then creates a new per-OEM handler hook, which should know how to handle
events with the OEM[012] Data Available flags set.  It then uses this to
implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which
are susceptable to setting the OEM[012] Data Available flags when the
driver can't handle it.

Subject: [PATCH] ipmi: clean up versioning of the IPMI driver

This adds MODULE_VERSION, MODULE_DESCRIPTION, and MODULE_AUTHOR tags to the
IPMI driver modules.  Also changes the MODULE_VERSION to remove the
prepended 'v' on each value, consistent with the module versioning policy.

This patch also removes all the version information from everything except
the ipmi_msghandler module.

Subject: [PATCH] ipmi: fix panic ipmb response

The "null message handler" in the IPMI driver is used in startup and panic
situations to handle messages.  It was only designed to work with messages
from the local management controller, but in some cases it was used to get
messages from remote managmenet controllers, and the system would then
panic.  This patch makes the "null message handler" in the IPMI driver more
general so it works with any kind of message.

Subject: [PATCH] ipmi: add hacks for IPMI chassis poweroff for certain Dell
 servers

This patch allows Dell servers with IPMI controllers that predate IPMI 1.5
to use the standard poweroff or powercycle commands.  These systems
firmware don't set the chassis capability bit in the Get Device ID, but
they do implement the standard poweroff and powercycle commands.

Tested on RHEL3 kernel 2.4.21-20.ELsmp on a PowerEdge 2600.  The standard
ipmi_poweroff driver cannot drive these systems.  With this patch, they
power off or powercycle as expected.

Subject: [PATCH] ipmi poweroff: fix chassis control

The IPMI power control function proc_write_chassctrl was badly written, it
directly used userspace pointers, it assumed that strings were NULL
terminated, and it used the evil sscanf function.  This converts over to
using the sysctl interface for this data and changes the semantics to be a
little more logical.
