All .c files should always include osdep as the first include
in the file, and .h files should never include osdep (we note
this in CODING_STYLE.rst).

If you added this #include to fix a compile issue that would
suggest that there's a .c file somewhere that's missing the
mandatory osdep include. I did a quick eyeball of all the files
that include xen_pt.h, though, and none of them are missing the
osdep include. So I think you should be able to simply drop the
osdep include here. If that produces an error, let us know what
fails and we can work out what's gone wrong.
