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
