I'm resending without the powerpc watchdog example. However if you decide to accept these changes for the next merge window, I may send the powerpc patch through your tree with appropriate acks, because it's not very intrusive. So the basic idea of these 4 patches is to allow arch specific (non-perf) hardlockup watchdogs to properly hook into the existing watchdog interfaces (cmdline, sysctl, kernel apis). sparc for example implements its own detector, but it can't use all the same sysctls, some cmdline options are a bit different, etc. powerpc wants to move to its own detector like sparc, but without causing interface functionality to change. Thanks, Nick Nicholas Piggin (4): watchdog: remove unused declaration watchdog: introduce arch_touch_nmi_watchdog() watchdog: split up config options watchdog: provide watchdog_reconfigure() for arch watchdogs arch/blackfin/include/asm/nmi.h | 2 + arch/blackfin/kernel/nmi.c | 2 +- arch/mn10300/include/asm/nmi.h | 2 + arch/mn10300/kernel/mn10300-watchdog-low.S | 8 +- arch/mn10300/kernel/mn10300-watchdog.c | 2 +- arch/powerpc/kernel/setup_64.c | 2 +- arch/sparc/include/asm/nmi.h | 1 + arch/sparc/kernel/nmi.c | 6 +- arch/x86/kernel/apic/hw_nmi.c | 2 +- include/linux/nmi.h | 58 ++++--- kernel/Makefile | 2 +- kernel/sysctl.c | 18 +- kernel/watchdog.c | 262 +++++++++++++++++++---------- kernel/watchdog_hld.c | 37 +--- lib/Kconfig.debug | 27 ++- 15 files changed, 261 insertions(+), 170 deletions(-) -- 2.11.0
