6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior bigeasy@linutronix.de
commit ff6cdc407f4179748f4673c39b0921503199a0ad upstream.
The erratum_1386_microcode array requires an empty entry at the end. Otherwise x86_match_cpu_with_stepping() will continue iterate the array after it ended.
Add an empty entry to erratum_1386_microcode to its end.
