ARM: 8820/1: mm: Stop printing the virtual memory layout
Since commit ad67b74d2469d9b8 ("printk: hash addresses printed with %p"), the virtual memory layout printed during boot up contains "ptrval" instead of actual addresses: Memory: 501296K/524288K available (6144K kernel code, 528K rwdata, 1944K rodata, 1024K init, 7584K bss, 22992K reserved, 0K cma-reserved) Virtual kernel memory layout: vector : 0xffff0000 - 0xffff1000 ( 4 kB) fixmap : 0xffc00000 - 0xfff00000 (3072 kB) vmalloc : 0xe0800000 - 0xff800000 ( 496 MB) lowmem : 0xc0000000 - 0xe0000000 ( 512 MB) modules : 0xbf000000 - 0xc0000000 ( 16 MB) .text : 0x(ptrval) - 0x(ptrval) (7136 kB) .init : 0x(ptrval) - 0x(ptrval) (1024 kB) .data : 0x(ptrval) - 0x(ptrval) ( 529 kB) .bss : 0x(ptrval) - 0x(ptrval) (7585 kB) Instead of changing the printing to "%px", and leaking virtual memory layout information again, just remove the printing completely, cfr. e.g. commits 071929dbdd865f77 ("arm64: Stop printing the virtual memory layout") and 31833332f7987636 ("m68k/mm: Stop printing the virtual memory layout"). All interesting information (actual section sizes) is already printed by mem_init_print_info() just above anyway.
