x86/cpu: Enable STIBP on AMD if Automatic IBRS is enabled (2023-07-22 18:04:22 +0200)
---------------------------------------------------------------- - AMD's automatic IBRS doesn't enable cross-thread branch target injection protection (STIBP) for user processes. Enable STIBP on such systems.
- Do not delete (but put the ref instead) of AMD MCE error thresholding sysfs kobjects when destroying them in order not to delete the kernfs pointer prematurely
- Restore annotation in ret_from_fork_asm() in order to fix kthread stack unwinding from being marked as unreliable and thus breaking livepatching
---------------------------------------------------------------- Kim Phillips (1): x86/cpu: Enable STIBP on AMD if Automatic IBRS is enabled
Peter Zijlstra (1): x86: Fix kthread unwind
Yazen Ghannam (1): x86/MCE/AMD: Decrement threshold_bank refcount when removing threshold blocks
