     10 * qemu_ram_mmap: mmap anonymous memory, the specified file or device.
     11 *
     12 * mmap() abstraction to map guest RAM, simplifying flag handling, taking
     13 * care of alignment requirements and installing guard pages.
     14 *
     15 * Parameters:
     16 *  @fd: the file or the device to mmap
     17 *  @size: the number of bytes to be mmaped
     18 *  @align: if not zero, specify the alignment of the starting mapping address;
     19 *          otherwise, the alignment in use will be determined by QEMU.
     20 *  @qemu_map_flags: QEMU_MAP_* flags
     21 *  @map_offset: map starts at offset of map_offset from the start of fd
     22 *
     23 * Internally, MAP_PRIVATE, MAP_ANONYMOUS and MAP_SHARED_VALIDATE are set
     24 * implicitly based on other parameters.
     25 *
     26 * Return:
     27 *  On success, return a pointer to the mapped area.
     28 *  On failure, return MAP_FAILED.
