commit daa4414aeb28321cd5c07f0eb40888bd86a851b7 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> AuthorDate: Tue May 30 16:03:16 2023 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Thu Aug 3 19:13:40 2023 +0100 x86/spec-ctrl: Update hardware hints * Rename IBRS_ALL to EIBRS. EIBRS is the term that everyone knows, and this makes ARCH_CAPS_EIBRS match the X86_FEATURE_EIBRS form. * Print RRSBA too, which is also a hint about behaviour.
