The hodgepodge in cpu/common.c was really not appropriate. - Folded Juergens XEN PV fix for vsyscall - Folded Peters ACCESS bit simplification - Cleaned up and fixed dump_pagetables - Added Vlastimils PTI/NOPTI marker for dumpstack - Addressed various minor review comments Diffstat against V163 appended. Thanks to everyone who looked and cared! It's perfect now because I'm going to have quiet holidays no matter what. Nevertheless, please review and test the hell out of it.
