2011-03-14watchdog: hpwdt: eliminate section mismatch warningAxel Lin
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.

2011-01-12watchdog: add CONFIG_WATCHDOG_NOWAYOUT support to PowerPC Book-E watchdog driverTimur Tabi
Normally, the watchdog is disabled when dev/watchdog is closed, but if CONFIG_WATCHDOG_NOWAYOUT is defined, then it means that the watchdog should remain enabled. So we should disable it only if CONFIG_WATCHDOG_NOWAYOUT is not defined. Also ensure that /dev/watchdog is only opened by one process at a time. That way, a second process can't accidentally disable the watchdog while the first process has it open. There shouldn't be any need for more than one process to open /dev/watchdog anyway.

2011-01-07x86: Convert some devices to use DIE_NMIUNKNOWNDon Zickus
They are a handful of places in the code that register a die_notifier as a catch all in case no claims the NMI. Unfortunately, they trigger on events like DIE_NMI and DIE_NMI_IPI, which depending on when they registered may collide with other handlers that have the ability to determine if the NMI is theirs or not. The function unknown_nmi_error() makes one last effort to walk the die_chain when no one else has claimed the NMI before spitting out messages that the NMI is unknown. This is a better spot for these devices to execute any code without colliding with the other handlers. The two drivers modified are only compiled on x86 arches I believe, so they shouldn't be affected by other arches that may not have DIE_NMIUNKNOWN defined.

2010-12-22x86, nmi_watchdog: Remove ARCH_HAS_NMI_WATCHDOG and rely on ↵Don Zickus
CONFIG_HARDLOCKUP_DETECTOR The x86 arch has shifted its use of the nmi_watchdog from a local implementation to the global one provide by kernel/watchdog.c. This shift has caused a whole bunch of compile problems under different config options. I attempt to simplify things with the patch below. In order to simplify things, I had to come to terms with the meaning of two terms ARCH_HAS_NMI_WATCHDOG and CONFIG_HARDLOCKUP_DETECTOR. Basically they mean the same thing, the former on a local level and the latter on a global level. With the old x86 nmi watchdog gone, there is no need to rely on defining the ARCH_HAS_NMI_WATCHDOG variable because it doesn't make sense any more. x86 will now use the global implementation. The changes below do a few things. First it changes the few places that relied on ARCH_HAS_NMI_WATCHDOG to use CONFIG_X86_LOCAL_APIC (the former was an alias for the latter anyway, so nothing unusual here). Those pieces of code were relying more on local apic functionality the nmi watchdog functionality, so the change should make sense. Second, I removed the x86 implementation of touch_nmi_watchdog(). It isn't need now, instead x86 will rely on kernel/watchdog.c's implementation. Third, I removed the #define ARCH_HAS_NMI_WATCHDOG itself from x86. And tweaked the include/linux/nmi.h file to tell users to look for an externally defined touch_nmi_watchdog in the case of ARCH_HAS_NMI_WATCHDOG _or_ CONFIG_HARDLOCKUP_DETECTOR. This changes removes some of the ugliness in that file. Finally, I added a Kconfig dependency for CONFIG_HARDLOCKUP_DETECTOR that said you can't have ARCH_HAS_NMI_WATCHDOG _and_ CONFIG_HARDLOCKUP_DETECTOR. You can only have one nmi_watchdog. Tested with ARCH=i386: allnoconfig, defconfig, allyesconfig, (various broken configs) ARCH=x86_64: allnoconfig, defconfig, allyesconfig, (various broken configs) Hopefully, after this patch I won't get any more compile broken emails. :-) v3: changed a couple of 'linux/nmi.h' -> 'asm/nmi.h' to pick-up correct function prototypes when CONFIG_HARDLOCKUP_DETECTOR is not set.

This touches lots of files mainly because of how the io_apic nmi_watchdog was implemented. Now that the io_apic nmi_watchdog is forever gone, remove all its fingers.

2010-10-28watchdog: iTCO_wdt.c: remove extra pci_dev_put()'s from init codePrarit Bhargava
The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove to fail because of an incorrect usage count. The probe for this driver does a for_each_pci_dev() which gets a reference for a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop puts a reference for a pci_dev when iTCO_wdt_init() fails, so the iTCO_wdt_init() does not need to do any pci_dev_put()'s. The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function. Signed-off-by: Prarit Bhargava <prarit@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>

2010-10-28watchdog: it8712f_wdt: Add module parameter for alternative reset sourcesTimo Juhani Lindfors
On iEi PCISA-9652-R10 (BIOS version 1.5) single board computer reads from the game port do not seem to reset the watchdog timer. This patch adds a module parameter wdt_config_reg to specify alternative reset sources. At least WDT_RESET_KBD has been tested, even just running while true; do setleds -L +scroll sleep 1 setleds -L -scroll sleep 1 done is enough to keep the watchdog happy.
