the pagebuf had been unlocked if the buffer was delwri. At high load, this
could result in a race when the superblock was being synced that would
result the flags being incorrect and the iodone functions being executed
incorrectly. This then leads to iclog callback failures or AIL list
corruptions resulting in filesystem shutdowns.

This is part of Thomas Gleixner's generic IRQ patch, which converts
ARM to use the generic IRQ subsystem. Here, we wrap calls to
desc->handler() in an inline function, desc_handle_irq(). This
reduces the size of Thomas' patch since the changes become more
localised.

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".

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.

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.

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.

Move pcibios_penalize_isa_irq() to pnpacpi_parse_allocated_irqresource().
Previously we passed the GSI, not the IRQ, and we did it even if parsing
the IRQ resource failed.
Parse IRQ descriptors that contain multiple interrupts. This violates the
spec (in _CRS, only one interrupt per descriptor is allowed), but some
firmware, e.g., HP rx7620 and rx8620 descriptions of HPET, has this bug.
