[PATCH 1/2] oprofile: Add HAVE_OPROFILE_NMI_TIMER

Hi Robert,

I couldn't come up with a case where it would be a benefit to us. We
roll out PMU support for a new CPU early so that the kernel and tools
support it when we GA. On the other hand adding oprofile NMI support
will put pressure on us to add more test cases.

I'll rework and resubmit. Thanks.
