watchdog: hpwdt: clean up set_memory_x call for 32 bit

2012-03-12T17:32:40Z

commit 97d2a10d5804d585ab0b58efbd710948401b886a upstream. 1. address has to be page aligned. 2. set_memory_x uses page size argument, not size. Bug causes with following commit: commit da28179b4e90dda56912ee825c7eaa62fc103797 Author: Mingarelli, Thomas Date: Mon Nov 7 10:59:00 2011 +0100 watchdog: hpwdt: Changes to handle NX secure bit in 32bit path commit e67d668e147c3b4fec638c9e0ace04319f5ceccd upstream. This patch makes use of the set_memory_x() kernel API in order to make necessary BIOS calls to source NMIs.

watchdog: hpwdt: Changes to handle NX secure bit in 32bit path

2012-01-06T22:14:00Z

commit e67d668e147c3b4fec638c9e0ace04319f5ceccd upstream. This patch makes use of the set_memory_x() kernel API in order to make necessary BIOS calls to source NMIs. This is needed for SLES11 SP2 and the latest upstream kernel as it appears the NX Execute Disable has grown in its control.

watchdog: shwdt: fix usage of mod_timer

2011-08-05T04:58:42Z

commit bea1906620ce72b63f83735c4cc2642b25ec54ae upstream. Fix the usage of mod_timer() and make the driver usable. mod_timer() must be called with an absolute timeout in jiffies. The old implementation used a relative timeout thus the hardware watchdog was never triggered.

watchdog: hpwdt depends on PCI

2011-07-17T12:40:08Z

hpwdt is a PCI driver so it should depend on PCI.

watchdog: fix hpwdt Kconfig regression in 3.0-rc

2011-07-16T06:06:12Z

Remove Kconfig regression caused by commit a4616153deae053b29a2b7dd9ec4b2a225accfc5 "watchdog: hpwdt: build hpwdt as module by default with NMI_DECODING enabled" With the above change applied, hpwdt will be enabled unconditionally by just entering the Watchdog subscreen in menuconfig. Since this driver is not essential to boot any box it should remain disabled until it gets manually enabled, just like all other drivers.

watchdog: mtx1-wdt: fix GPIO toggling

2011-06-28T07:42:30Z

Commit e391be76 (MIPS: Alchemy: Clean up GPIO registers and accessors) changed the way the GPIO was toggled. Prior to this patch, we would always actively drive the GPIO output to either 0 or 1, this patch drove the GPIO active to 0, and put the GPIO in tristate to drive it to 1, unfortunately this does not work, revert back to active driving. Using a signed variable (gstate) to hold the gpio state and using a bit- wise operation on it also resulted in toggling value from 1 to -2 since the variable is signed. This value was then passed on to gpio_direction_ output, which always perform a if (value) ... to set the value to the gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...
