Borislav Petkov (AMD) 8cc68c9c9e x86/CPU/AMD: Make sure EFER[AIBRSE] is set ... The AutoIBRS bit gets set only on the BSP as part of determining which mitigation to enable on AMD. Setting on the APs relies on the circumstance that the APs get booted through the trampoline and EFER - the MSR which contains that bit - gets replicated on every AP from the BSP. However, this can change in the future and considering the security implications of this bit not being set on every CPU, make sure it is set by verifying EFER later in the boot process and on every AP.
