* 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 ... Manually fix trivial conflict with task pid container helper changes in arch/x86/kernel/process_32.c
