Date: Mon, 25 Sep 2006 09:49:36 +1000 From: Keith Owens <kaos@....com.au> To: linux-kernel@...r.kernel.org Subject: [patch 2.6.18] Make touch_nmi_watchdog fall back to touch_softlockup_watchdog Some architectures define their own touch_nmi_watchdog and these all include a call to touch_softlockup_watchdog. Change all architectures so touch_nmi_watchdog includes a call to touch_softlockup_watchdog, to get a consistent soft watchdog state. Also take the opportunity to kill ARCH_HAS_NMI_WATCHDOG.
