Merge branch 'core-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull watchdog core update from Thomas Gleixner:
"A single commit adding a command line parameter which allows to set
the watchdog threshold on the kernel command-line, so kernels with
massive debug facilities enabled won't trigger the watchdog during
early boot and before the threshold can be changed via sysctl"
* 'core-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
