Looks like we currently have this:

Memory: 2033088K/2095100K available (7376K kernel code, 784K rwdata,
2312K rodata, 1024K init, 8117K bss, 45628K reserved,
16384K cma-reserved, 1292284K highmem)
Virtual kernel memory layout:
    vector  : 0xffff0000 - 0xffff1000   (   4 kB)
    fixmap  : 0xffc00000 - 0xfff00000   (3072 kB)
