From: Sebastian Andrzej Siewior Date: Tue, 26 Nov 2024 13:47:22 +0000 (+0100) Subject: x86/CPU/AMD: Terminate the erratum_1386_microcode array X-Git-Tag: v6.11.11~109 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=82d6b82cf89d950982ac240ba068c3a7e1f23b0a;p=thirdparty%2Fkernel%2Fstable.git x86/CPU/AMD: Terminate the erratum_1386_microcode array 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.
