    The ioremap can be easily tracked by kmemleak (it is on my to-do list
    but haven't managed to do it yet). That's not far from vmalloc.

    The page allocator is a bit more difficult since it's used by the slab
    allocator as well and it may lead to some recursive calls into
    kmemleak. I'll have a think.

    Anyway, you can leak memory without this being detected by kmemleak -
    just add the allocated objects to a list and never remove them.
