I have to disagree here.
After looking at the code in parse_config_data(), tot_memkb is only set
if actmem= is listed in the configfile. And if actmem= is set, its the
trigger to run xenpaging and let it work toward the specified number.
So checking for a non-null tot_memkb in create_xenpaging() looks like
the correct way to me to decide wether xenpaging should be started.
