#     selftests/powerpc: Suggest memtrace instead of /dev/mem for ci memory
#     
#     The suggested alternative for getting cache-inhibited memory with 'mem='
#     and /dev/mem is pretty hacky. Also, PAPR guests do not allow system
#     memory to be mapped cache-inhibited so despite /dev/mem being available
#     this will not work which can cause confusion.  Instead recommend using
#     the memtrace buffers. memtrace is only available on powernv so there
#     will not be any chance of trying to do this in a guest.
