    It's called "memory mapped IO" and "IO memory" is a word that you can
    decypher the moment you hear it. So, let me say for the record: I like
    it.

    Linus, wasn't it your intention to have the Linux "mm" tree grab

    0x00000000 - 0x000a0000 &
    0x00100000 - 0x04000000(*)

    as the "iomem" (commonly known as main memory) regions that it would
    handle, leaving the 640k-1M region free for real IOmem? Wouldn't the
    vmalloc be supposed to grab:

    0x04800000 - 0x08800000 ?

    and things like that? This would make the name "io memory" even too
    specific. But still, iomem is in my opinion a much better name than
    something that has "pci".

    Roger.
