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:
"Implement multi-die topology support on Intel CPUs and expose the die
topology to user-space tooling, by Len Brown, Kan Liang and Zhang Rui.
These changes should have no effect on the kernel's existing
understanding of topologies, i.e. there should be no behavioral impact
on cache, NUMA, scheduler, perf and other topologies and overall
system performance"
