* qemu_ram_mmap: mmap the specified file or device.
* Parameters:
* @fd: the file or the device to mmap
* @size: the number of bytes to be mmaped
* @align: if not zero, specify the alignment of the starting mapping address;
* otherwise, the alignment in use will be determined by QEMU.
* @shared: map has RAM_SHARED flag.
* @is_pmem: map has RAM_PMEM flag.
* Return:
* On success, return a pointer to the mapped area.
* On failure, return MAP_FAILED.
