Log: Remove _PROF_PROLOGUE from the EENTRY() macros. These macros define 'extra' entry points which are nested within or provide a synonym name for another function. It's most likely not safe to be messing with the IP and LR registers at anything other than the primary entry point to a function. Anywhere beyond initial function entry, those registers may be in use as scratch or variable registers.
