2019-11-07qcow2-bitmap: Fix uint64_t left-shift overflowTuguoyi
There are two issues in In check_constraints_on_bitmap(), 1) The sanity check on the granularity will cause uint64_t integer left-shift overflow when cluster_size is 2M and the granularity is BIGGER than 32K. 2) The way to calculate image size that the maximum bitmap supported can map to is a bit incorrect.

2019-11-06virtio: notify virtqueue via host notifier when availableStefan Hajnoczi
Host notifiers are used in several cases: 1. Traditional ioeventfd where virtqueue notifications are handled in the main loop thread. 2. IOThreads (aio_handle_output) where virtqueue notifications are handled in an IOThread AioContext. 3. vhost where virtqueue notifications are handled by kernel vhost or a vhost-user device backend. Most virtqueue notifications from the guest use the ioeventfd mechanism, but there are corner cases where QEMU code calls virtio_queue_notify(). This currently honors the host notifier for the IOThreads aio_handle_output case, but not for the vhost case. The result is that vhost does not receive virtqueue notifications from QEMU when virtio_queue_notify() is called. This patch extends virtio_queue_notify() to set the host notifier whenever it is enabled instead of calling the vq->(aio_)handle_output() function directly. We track the host notifier state for each virtqueue separately since some devices may use it only for certain virtqueues. This fixes the vhost case although it does add a trip through the eventfd for the traditional ioeventfd case. I don't think it's worth adding a fast path for the traditional ioeventfd case because calling virtio_queue_notify() is rare when ioeventfd is enabled.

2019-11-06hw/rdma: Utilize ibv_reg_mr_iova for memory registrationYuval Shaia
The virtual address that is provided by the guest in post_send and post_recv operations is related to the guest address space. This address space is unknown to the HCA resides on host so extra step in these operations is needed to adjust the address to host virtual address. This step, which is done in data-path affects performances. An enhanced verion of MR registration introduced here https://patchwork.kernel.org/patch/11044467/ can be used so that the guest virtual address space for this MR is known to the HCA in host. This will save the data-path adjustment.

The function reg_mr_iova is an enhanced version of ibv_reg_mr function that can help to easly register and use guest's MRs. Add check in 'configure' phase to detect if we have libibverbs with this support.

2019-11-05hw/i386: Remove obsolete LoadStateHandler::load_state_old handlersPhilippe Mathieu-Daudé
These devices implemented their load_state_old() handler 10 years ago, previous to QEMU v0.12. Since commit cc425b5ddf removed the pc-0.10 and pc-0.11 machines, we can drop this code. Note: the mips_r4k machine started to use the i8254 device just after QEMU v0.5.0, but the MIPS machine types are not versioned, so there is no migration compatibility issue removing this handler.
