[Qemu-devel] [PATCH v2 0/9] RCUification of the memory API, part 2

[Paolo Bonzini]

Part 2 converts ram_list to RCU.  It is enough of a base for Stefan's
work on thread-safe migration bitmaps.  TCG folks, please review.

Parts 3 (posted today) and 3.5 (to be done) will separate removal and
reclamation of device data.  Part 4 will switch KVM MMIO and PIO to
unlocked lookup and convert a single device to unlocked access.
