SubjectRe: 2.1.63 - testing Pentium bug workaround..

From: Linus Torvalds <torvalds@transmeta.com>

But maybe people should start looking for other complex
instructions that are lockable.. (the only other complex
instruction I can think of is the bitmap instructions - bt, bts,
btc, btr - but they don't actually have an illegal addressing
mode).

I would expect possible bugs in the mul/div insns with lock prefixes,
they can be locked can't they? If so do they have illegal addressing
modes you can form invalid opcodes with?

Later,
