Robert Watson a12df97ed2 Adjust PROF_ARTIFICIAL_FRAMES in the DTrace profile provider on ARM to ... skip 10, rather than 9, frames. This appears to work quite well in practice on the BeagleBone Black, so remove a comment about the value being bogus and replace it with a slightly less negative one. However, the number of frames to skip is quite sensitive to details of the timer and interrupt handling paths, so this is necessarily fragile -- but no more so than on x86.
