    x86/e820: Set System RAM type and descriptor · f33b14a4
    Toshi Kani authored
    Change e820_reserve_resources() to set 'flags' and 'desc' from
    e820 types.
    
    Set E820_RESERVED_KERN and E820_RAM's (System RAM) io resource
    type to IORESOURCE_SYSTEM_RAM.
    
    Do the same for "Kernel data", "Kernel code", and "Kernel bss",
    which are child nodes of System RAM.
    
    I/O resource descriptor is set to 'desc' for entries that are
    (and will be) target ranges of walk_iomem_res() and
    region_intersects().
