commit fc55f386de46aef2c96789f0e7cb2e53a7816d7d
Author: Petr Malat <address@hidden>
Date:   Thu Dec 15 14:19:58 2016 +0100

    Read the address using strtoul(). If strtol() is used and the number is
    bigger than LONG_MAX, LONG_MAX is returned instead, which leads to a failure
    if the mapping address is 0x80000000 or larger on 32-bit platforms (and
    similarly for 64-bit platforms).
