Subject: [PATCH v2 0/4] x86/CPU: Update AMD Last-Level-Cache Information

First, clean up last-level-cache parameters so that it could not
require ifdef CONFIG_SMP. Then, consolidate cache-info-related
code for x86 into arch/x86/kernel/cpu/cacheinfo.c.

Finally, for AMD, introduce new logic to derive LLC ID from APIC ID.

Thanks,
Suravee

Changes from V1 (https://lkml.org/lkml/2018/3/26/24)
 * 4/4: Do not EXPORT_SYMBOL_GPL for cacheinfo_amd_init_llc_id.

  x86/CPU/AMD: Remove unnecessary check for CONFIG_SMP
  x86/CPU: Rename intel_cacheinfo.c to cacheinfo.c

Suravee Suthikulpanit (2):
  perf/x86/amd/uncore: Fix amd_uncore_llc ID to use pre-defined
    cpu_llc_id
  x86/CPU/AMD: Calculate LLC ID from number of sharing threads
