#     powerpc/64: barrier_nospec: Add commandline trigger
#     
#     Add commandline options spectre_v2 and nospectre_v2
#     
#     These are named same as similar x86 options regardless of actual effect
#     to not require platform-specific configuration.
#     
#     Supported options:
#     nospectre_v2 or spectre_v2=off - speculation barrier not used
#     spectre_v2=on or spectre_v2=auto - speculation barrier used
#     
#     Changing the settings after boot is not supported and VM migration may
#     change requirements so auto is same as on.
#     
#     Based on s390 implementation
#
