Merge phase #4 (X2APIC, APIC unification, CPU identification unification) of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

* 'x86-v28-for-linus-phase4-D' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (186 commits)
  x86, debug: print more information about unknown CPUs
  x86 setup: handle more than 8 CPU flag words
  x86: cpuid, fix typo
  x86: move transmeta cap read to early_init_transmeta()
  x86: identify_cpu_without_cpuid v2
  x86: extended "flags" to show virtualization HW feature in /proc/cpuinfo
  x86: move VMX MSRs to msr-index.h
  x86: centaur_64.c remove duplicated setting of CONSTANT_TSC
  x86: intel.c put workaround for old cpus together
  x86: let intel 64-bit use intel.c
  x86: make intel_64.c the same as intel.c
  x86: make intel.c have 64-bit support code
  x86: little clean up of intel.c/intel_64.c
  x86: make 64 bit to use amd.c
  x86: make amd_64 have 32 bit code
  x86: make amd.c have 64bit support code
  x86: merge header in amd_64.c
  x86: add srat_detect_node for amd64
  x86: remove duplicated force_mwait
  x86: cpu make amd.c more like amd_64.c v2
