TRPM,CPUM: Return to v8086 mode fixes.

  • We may have entered from protected mode and be returning to V8086 mode, so the larger V8086 frame always has to be pushed. TRPM should call CPUMGCCallV86Code instead of duplicating the code.
  • We must clear the valid bit in all the selectors when returning to v8086 mode to make sure we reload the hidden bits the next time we need them, since v8086 and protect mode are very different and our checks could get confused.
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
