    powerpc/mm/radix: remove useless kernel messages · ec5b705c
    Qian Cai authored
    Booting a POWER9 PowerNV system generates a few messages below with
    "____ptrval____" due to the pointers printed without a specifier
    extension (i.e unadorned %p) are hashed to prevent leaking information
    about the kernel memory layout.
