commit 60be6340796e66b5ac8aac2d98dde5c79336a89c
Author: Denis V. Lunev <den@xxxxxxxxxx>

    migration: fix deadlock
    
    Release qemu global mutex before call synchronize_rcu().
    synchronize_rcu() waiting for all readers to finish their critical
    sections. There is at least one critical section in which we try
    to get QGM (critical section is in address_space_rw() and
    prepare_mmio_access() is trying to aquire QGM).
    
    Both functions (migration_end() and migration_bitmap_extend())
    are called from main thread which is holding QGM.
    
    Thus there is a race condition that ends up with deadlock:
    main thread     working thread
    Lock QGA                |
    |             Call KVM_EXIT_IO handler
    |                       |
    |        Open rcu reader's critical section
    Migration cleanup bh    |
    |                       |
    synchronize_rcu() is    |
    waiting for readers     |
    |            prepare_mmio_access() is waiting for QGM
      \                   /
             deadlock
    
    The patch changes bitmap freeing from direct g_free after synchronize_rcu
    to free inside call_rcu.

    migration: announce VM's new home just before VM is runnable
    
    We were announcing the dest host's IP as our new IP a bit too soon -- if
    there were errors detected after this announcement was done, the
    migration is failed and the VM could continue running on the src host --
    causing problems later.
    
    Move around the qemu_announce_self() call so it's done just before the
    VM is runnable.

    Migration: Generate the completed event only when we complete
    
    The current migration-completed event is generated a bit too early,
    which means that an eager libvirt that's ready to go as soon
    as it sees the event ends up racing with the actual end of migration.
    
    This corresponds to RH bug:
