linux-next: manual merge of the tip tree with Linus' tree

Hi all,

Today's linux-next merge of the tip tree got a conflict in
arch/x86/kernel/cpu/perf_event_intel_uncore.c between commit 2c666adacc9e
("x86, intel, uncore: Fix CPU hotplug callback registration") from Linus'
tree and commit 411cf180fa00 ("perf/x86/uncore: fix initialization of
cpumask") from the tip tree.

I fixed it up (maybe incorrectly - see below) and can carry the fix as
necessary (no action is required).
