#     
#     Pull x86 IBPB fixes from Borislav Petkov:
#      "This fixes the IBPB implementation of older AMDs (< gen4) that do not
#       flush the RSB (Return Address Stack) so you can still do some leaking
#       when using a "=ibpb" mitigation for Retbleed or SRSO. Fix it by doing
#       the flushing in software on those generations.
#     
#       IBPB is not the default setting so this is not likely to affect
#       anybody in practice"

#       x86/bugs: Do not use UNTRAIN_RET with IBPB on entry
#       x86/bugs: Skip RSB fill at VMEXIT
#       x86/entry: Have entry_ibpb() invalidate return predictions
#       x86/cpufeatures: Add a IBPB_NO_RET BUG flag
