Sir Richard 6aa9cce4bb [NTOS]: Try to fix KiEnterInterrupt once and for all. Only set segments for V8086 or user traps.
[NTOS]: Rework the way traps with possibly dirty DS/ES segments are handled. The FAST V86 hack is gone. Intead, created a "safe" version of IsTrapV86 and IsTrapUser that does an SS segment dereference (known good). The condition is then based on this, and the segments are saved and loaded safely. Note that for GCC 4.5 the ASM can be improved to directly branch or not to a label, instead of returning a boolean that is then further compared before branching.
This will fix certain exceptions that were seen in KeUpdateSystemTime, and might fix the sneaking HalpTrap0D while not in V86 mode (no promises).
