[Qemu-devel] [PATCH v4 00/35] cmpxchg-based emulation of atomics |

Rebased on top of Paolo's safe-work series, which means
that we now have cpu_exec_step_atomic for system mode as
well as linux-user. This should fix the problems with
atomic access to notdirty pages that have been reported.
Folded in some feedback from Alex from v3.
