Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull misc fixes from Thomas Gleixner:
"This update contains:
- a fix for stomp-machine so the nmi_watchdog wont trigger on the cpu
waiting for the others to execute the callback
- various fixes and updates to objtool including an resync of the
instruction decoder to match the kernel's decoder"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
objtool: Un-capitalize "Warning" for out-of-sync instruction decoder
objtool: Resync x86 instruction decoder with the kernel's
objtool: Support new GCC 6 switch jump table pattern
stop_machine: Touch_nmi_watchdog() after MULTI_STOP_PREPARE
objtool: Add 'fixdep' to objtool/.gitignore
