    SubjectBug in ioremap: boundary case is wrong
    The x86 ioremap starts with

    if(phys_addr > virt_to_phys(high_memory))
    return phys_to_virt(phys_addr);

    If you vremap an area whose end point is over the high_memory point your
    memory mapping breaks. Surely it should be

    if( phys_addr + size > ...)
