Merge branch 'core-debug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core debug changes from Ingo Molnar: "Currently there are two methods to set the panic_timeout: via 'panic=X' boot commandline option, or via /proc/sys/kernel/panic. This tree adds a third panic_timeout configuration method: configuration via Kconfig, via CONFIG_PANIC_TIMEOUT=X - useful to distros that generally want their kernel defaults to come with the .config. CONFIG_PANIC_TIMEOUT defaults to 0, which was the previous default value of panic_timeout. Doing that unearthed a few arch trickeries regarding arch-special panic_timeout values and related complications - hopefully all resolved to the satisfaction of everyone" * 'core-debug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: powerpc: Clean up panic_timeout usage MIPS: Remove panic_timeout settings panic: Make panic_timeout configurable
