[PATCH] ARM: mm: Stop printing the virtual memory layout

[Geert Uytterhoeven]

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.
