Since 1c48a5c93da6313 (dt: Eliminate of_platform_{,un}register_driver)
mpc8xxx_wdt no longer builds as it tries to refer to a 'match' variable
rather than ofdev->dev.of_match that it checks just before.Signed-off-by: Peter Korsgaard

This is needed for determining the reason for failure when a softdog
timeout occurs.We use softdog to watch for critical application failures and at the
minimum a snapshot of the system would help to determine the cause. In
such a scenario the application could fail but there isn't a softlockup as
such, hence the detect softlockup feature does not help.The patch adds a module parameter soft_panic which when set to 1 causes
softdog to invoke panic instead of reboot when the softdog timer expires.
By invoking panic we execute kdump if it is configured and the vmcore
generated by kdump should provide atleast a minimal idea of the reason for
failure.Based on an original patch by Ken Sugawara

Improve the status messages that are displayed during some operations of the
PowerPC watchdog timer driver. When the watchdog is enabled, the timeout is
displayed as a number of seconds, instead of an obscure "period". The "period"
is the position of a bit in a 64-bit timer register. The higher the value,
the quicker the watchdog timeout occurs. Some people chose a high "period"
value for the timer and get confused as to why the board resets within a
few seconds.Messages displayed during open and close are now debug messages, so that they
don't clutter the console by default. Finally, printk() is replaced with the
pr_xxx() equivalent.Signed-off-by: Timur Tabi

This submission includes:
- Fix to intel_scu_write() to start watchdog timer the on the
first write, and refresh on subsequent writes.
This enables Open, write, write, ... usage model.
- Moves boot parameter checks from intel_scu_open() to
intel_scu_watchdog_init(), so driver init will fail if these
parameters are out of bounds.
- Adds check for whether process waiting in wait_event_interruptible()
received a signal while it was waiting.
- Other small error handling changes.Removed the read() method for now as that wass a non-standard behaviour.

hpwdt_init_nmi_decoding() is called in hpwdt_init_one error handling,
thus remove the __devexit annotation of hpwdt_exit_nmi_decoding().This patch fixes below warning:
WARNING: drivers/watchdog/hpwdt.o(.devinit.text+0x36f): Section mismatch in reference from the function hpwdt_init_one() to the function .devexit.text:hpwdt_exit_nmi_decoding()
The function __devinit hpwdt_init_one() references
a function __devexit hpwdt_exit_nmi_decoding().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __devexit annotation of
hpwdt_exit_nmi_decoding() so it may be used outside an exit section.Signed-off-by: Axel Lin
