Merge branch 'core/percpu' into perfcounters/core
Conflicts: arch/x86/include/asm/pda.h We merge tip/core/percpu into tip/perfcounters/core because of a semantic and contextual conflict: the former eliminates the PDA, while the latter extends it with apic_perf_irqs field. Resolve the conflict by moving the new field to the irq_cpustat structure on 64-bit too. Signed-off-by: Ingo Molnar <mingo@elte.hu>
