Merge branch 'x86-topology-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 topology updates from Ingo Molnar:
"Two main changes: preparatory changes for Intel multi-die topology
support, plus a syslog message tweak"
* 'x86-topology-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/topology: Make DEBUG_HOTPLUG_CPU0 pr_info() more descriptive
x86/smpboot: Rename match_die() to match_pkg()
topology: Simplify cputopology.txt formatting and wording
x86/topology: Fix documentation typo
