Hi, Michael

this patch-set will break normal build(without --enable-mc):

migration.c: In function ‘migrate_rdma_pin_all’:
migration.c:564: error: ‘MIGRATION_CAPABILITY_X_RDMA_PIN_ALL’ undeclared (first use in this function)
migration.c:564: error: for each function it appears in.)

Thanks!

Changes since v1:

1. Re-based against Juan's improved migration_bitmap performance changes
2. Overhauled RDMA support to prepare for better usage of RDMA in
    other parts of the QEMU code base (such as storage).
3. Fix for netlink issues that failed to cleanup the network buffer
    device for development testing.

Michael R. Hines (12):
   mc: add documentation for micro-checkpointing
   mc: timestamp migration_bitmap and KVM logdirty usage
   mc: introduce a 'checkpointing' status check into the VCPU states
   mc: support custom page loading and copying
   rdma: accelerated memcpy() support and better external RDMA user
     interfaces
   mc: introduce state machine changes for MC
   mc: introduce additional QMP statistics for micro-checkpointing
   mc: core logic
   mc: configure and makefile support
   mc: expose tunable parameter for checkpointing frequency
   mc: introduce new capabilities to control micro-checkpointing
   mc: activate and use MC if requested
