Part 1 is patches 1-7, part 2 is patches 8-15.
Part 1 changes requested by reviewers were minimal, but no one really
provided a Reviewed-by so I'm reposting. The idea is to send a pull
request for part 1 soon.
These two parts are enough of a base for Stefan's work on thread-safe
migration bitmaps.
Part 3 (in the works) will separate removal and reclamation of device
data. Part 4 (already done) will switch KVM MMIO and PIO to unlocked
lookup and convert a single device to unlocked access.
Changes in part 1:
- patch 1: left aside for later (Peter)
- patch 2 (now patch 1): two small doc fixes (Fam)
- patch 3 (now patch 2): do not do both short and long tests (Fam)
do not drop rcu_register_thread in rcu_init (Fam)
TCG folks, please review patches 8 and 9. Note that they are not
yet ready for multiple TCG threads.
