There's still some assumptions in the oprofile code, which breaks the build with 
your patch applied:

 arch/x86/oprofile/op_model_p4.c:394:4: error: implicit declaration of function ‘release_perfctr_nmi’
 arch/x86/oprofile/op_model_p4.c:403:4: error: implicit declaration of function ‘release_evntsel_nmi’
 arch/x86/oprofile/op_model_p4.c:419:3: error: implicit declaration of function ‘reserve_perfctr_nmi’
 arch/x86/oprofile/op_model_p4.c:428:3: error: implicit declaration of function ‘reserve_evntsel_nmi’

Config attached.

Thanks,

	Ingo
