This requires some abstraction in a few places when setting %cs or checking privilege level (user vs kernel).I made some changes: a. Added some comments about the SEGMENT_IS_*_CODE() macros. b. Added a USER_RPL macro. (You were comparing a value to a mask in some places and to the magic number 3 in other places.) c. Changed the entry.S tests for LDT stack segment to use the macros. These changes look great. Ack-ed. I had some similar ones before that never made it from my tree, as I got carried away and tried to unify the user descriptor conversion functions... someday I'll get to it again.
