Subject[PATCH v2 0/4] locking/qspinlock, x86: Improve determinism for x86
Back when Will did his qspinlock determinism patches, we were left with one
cmpxchg loop on x86 due to the use of atomic_fetch_or(). Will proposed a nifty
trick:

While that didn't quite work, this series implements that basic idea.

Changes since v1:

- Adjusted comments in #2, wildea01
- 'Simplified' GEN_*_RMWcc, peterz
- Rewrote _the_ patch to use BTS, wildea01
