  x86, lapic-timer: Increase the max_delta to 31 bits
  x86: Fix sparse non-ANSI function warnings in smpboot.c
  x86, numa: Fix CONFIG_DEBUG_PER_CPU_MAPS without NUMA emulation
  x86, AMD, PCI: Add AMD northbridge PCI device id for CPU families 12h and 14h
  x86, numa: Fix cpu to node mapping for sparse node ids
  x86, numa: Fake node-to-cpumask for NUMA emulation
  x86, numa: Fake apicid and pxm mappings for NUMA emulation
  x86, numa: Avoid compiling NUMA emulation functions without CONFIG_NUMA_EMU
  x86, numa: Reduce minimum fake node size to 32M
