Merge ssh://master.kernel.org/pub/scm/linux/kernel/git/tglx/linux-2.6-x86

* ssh://master.kernel.org/pub/scm/linux/kernel/git/tglx/linux-2.6-x86: (33 commits)
  x86: convert cpuinfo_x86 array to a per_cpu array
  x86: introduce frame_pointer() and stack_pointer()
  x86 & generic: change to __builtin_prefetch()
  i386: do not BUG_ON() when MSR is unknown
  x86: acpi use cpu_physical_id
  x86: convert cpu_llc_id to be a per cpu variable
  x86: convert cpu_to_apicid to be a per cpu variable
  i386: introduce "used_vectors" bitmap which can be used to reserve vectors.
  x86: use raw locks during oopses
  x86: honor _PAGE_PSE bit on page walks
  i386: do cpuid_device_create() in CPU_UP_PREPARE instead of CPU_ONLINE.
  x86: implement missing x86_64 function smp_call_function_mask()
  x86: use descriptor's functions instead of inline assembly
  i386: consolidate show_regs and show_registers for i386
  i386: make callgraph use dump_trace() on i386/x86_64
  x86: enable iommu_merge by default
  i386: i386 add AMD64 Barcelona PMU MSR definitions to msr.h
  x86: Unify i386 and x86-64 early quirks
  x86: enable HPET on ICH3 and ICH4
  x86: force enable HPET on VT8235/8237 chipsets
  ...
