Subject: linux-next: manual merge of the percpu tree with the tip tree

Hi all,

Today's linux-next merge of the percpu tree got a conflict in
arch/x86/kernel/cpu/intel_cacheinfo.c between commit
ebb682f522411abbe358059a256a8672ec0bd55b ("x86, AMD: Fix stale
cpuid4_info shared_map data in shared_cpu_map cpumasks") from the tip
tree and commit 0fe1e009541e925adc1748a605d8b66188e4b2ab ("percpu: make
percpu symbols in x86 unique") from the percpu tree.

Just context changes.  I fixed it up (see below) and can carry the fix as
necessary.
