The comment is wrong, which was already the case before but it becomes a
bit more important if the function is used outside its module.
However, why not use get_xsave_addr? I don't see why it is important to
skip the checks, and if it is it probably deserves a comment. "Raw" and
double underscores in the function name is scary...
