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.
