Merge tag 'x86_bugs_for_6.7_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 hw mitigation updates from Borislav Petkov: - A bunch of improvements, cleanups and fixlets to the SRSO mitigation machinery and other, general cleanups to the hw mitigations code, by Josh Poimboeuf - Improve the return thunk detection by objtool as it is absolutely important that the default return thunk is not used after returns have been patched. Future work to detect and report this better is pending - Other misc cleanups and fixes * tag 'x86_bugs_for_6.7_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (21 commits) x86/retpoline: Document some thunk handling aspects x86/retpoline: Make sure there are no unconverted return thunks due to KCSAN x86/callthunks: Delete unused "struct thunk_desc" x86/vdso: Run objtool on vdso32-setup.o objtool: Fix return thunk patching in retpolines x86/srso: Remove unnecessary semicolon x86/pti: Fix kernel warnings for pti= and nopti cmdline options x86/calldepth: Rename __x86_return_skl() to call_depth_return_thunk() x86/nospec: Refactor UNTRAIN_RET[_*] x86/rethunk: Use SYM_CODE_START[_LOCAL]_NOALIGN macros x86/srso: Disentangle rethunk-dependent options x86/srso: Move retbleed IBPB check into existing 'has_microcode' code block x86/bugs: Remove default case for fully switched enums x86/srso: Remove 'pred_cmd' label x86/srso: Unexport untraining functions x86/srso: Improve i-cache locality for alias mitigation x86/srso: Fix unret validation dependencies x86/srso: Fix vulnerability reporting for missing microcode x86/srso: Print mitigation for retbleed IBPB case x86/srso: Print actual mitigation if requested mitigation isn't possible ...
