6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
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.
Fixes: 29ba89f189528 ("x86/CPU/AMD: Improve the erratum 1386 workaround")
