    For Spectre variant 2 mitigation, individual user programs

+   On legacy IBRS systems, at return to userspace, implicit STIBP is disabled

    On x86, this will turn on STIBP to guard against attacks from the
    sibling thread when the user program is running, and use IBPB to
    flush the branch target buffer when switching to/from the program.
