The SAMPLE_FEED_* events are inherited through ArchStdEvent by the neoverse-n3, neoverse-v3 and t410 tables, so the misspelling reaches those three generated tables. The a64fx pair appears once, because the long description is dropped when it equals the brief one. Spell the words correctly. Event names, codes and expressions are unchanged. Written with Hermes Agent, an LLM assistant. Running jevents.py for arm64 before and after this change removes 12 occurrences of "Statisical" and the one "prefecher" from the generated string table; perf was not rebuilt.
