$ git grep '\bpr_' mm/memblock.c
mm/memblock.c: pr_info(fmt, ##__VA_ARGS__); \
mm/memblock.c: pr_warn("Could not allocate %pap bytes of mirrored memory\n",
mm/memblock.c: pr_err("memblock: Failed to double %s array from %ld to %ld entries !\n",
mm/memblock.c: pr_warn("Could not allocate %pap bytes of mirrored memory\n",
mm/memblock.c: pr_warn("%s: No memory registered yet\n", __func__);
mm/memblock.c: pr_info(" %s.cnt = 0x%lx\n", type->name, type->cnt);
mm/memblock.c: pr_info(" %s[%#x]\t[%pa-%pa], %pa bytes%s flags: %#x\n",
mm/memblock.c: pr_info("MEMBLOCK configuration:\n");
mm/memblock.c: pr_info(" memory size = %pa reserved size = %pa\n",
