Robert Richter c7c25802b3 arch/x86/oprofile/op_model_amd.c: Perform initialisation on a single CPU ... Disable preemption in init_ibs(). The function only checks the ibs capabilities and sets up pci devices (if necessary). It runs only on one cpu but operates with the local APIC and some MSRs, thus it is better to disable preemption.
