  - [lib][memlog] Don't map more than requested
    
    The old code rounded the start and end address to map to 1 mb boundrary.
    This does not work if we want to validate that the memory we map belongs
    to the client os. Instead only map the region requested, and reject
    non-page aligned requests.
