#     powerpc/powernv: Restrict OPAL symbol map to only be readable by root
#     
#     Currently the OPAL symbol map is globally readable, which seems bad as
#     it contains physical addresses.
#     
#     Restrict it to root.
#     
#     Fixes: c8742f85125d ("powerpc/powernv: Expose OPAL firmware symbol map")
