Amit Shah d6258c93a7 virtio-serial: make flow control explicit in virtio-console
virtio-console.c used to return a value less than the number of bytes
asked to be written out to a chardev backend in case the backend is not
writable.  virtio-serial-bus.c then implicitly enabled flow control for
that port.

Make this explicit instead.

Kuo-Jung Su 0bc472a9d6 hw/nand.c: correct the sense of the BUSY/READY status bit
The BIT6 of Status Register(SR):

SR[6] behaves the same as R/B# pin
    SR[6] = 0 indicates the device is busy;
    SR[6] = 1 means the device is ready

Some NAND flash controller (i.e. ftnandc021) relies on the SR[6]
to determine if the NAND flash erase/program is success or error timeout.

P.S:
The exmaple NAND flash datasheet could be found at following link:

Paolo Bonzini 0c92e0e6b6 scsi-disk: handle io_canceled uniformly and correctly
Always check it immediately after calling bdrv_acct_done, and
always do a "goto done" in case the "done" label has to free
some memory---as is the case for scsi_unmap_complete in the
previous patch.

This patch could fix problems that happen when a request is
split into multiple parts, and one of them is canceled.  Then
the next part is fired, but the HBA's cancellation callbacks have
fired already.  Whether this happens or not, depends on how the
block/ driver implements AIO cancellation.  It it does a simple
bdrv_drain_all() or similar, then it will not have a problem.
If it only cancels the given AIOCB, this scenario could happen.

Paolo Bonzini 2c20e711de dataplane: remove EventPoll in favor of AioContext
During the review of the dataplane code, the EventPoll API morphed itself
(not concidentially) into something very very similar to an AioContext.
Thus, it is trivial to convert virtio-blk-dataplane to use AioContext,
and a first baby step towards letting dataplane talk directly to the
QEMU block layer.

The only interesting note is the value-copy of EventNotifiers.  At least
in my opinion this is part of the EventNotifier API and is even portable
to Windows.  Of course, in this case you should not close the notifier's
underlying file descriptors or handle with event_notifier_cleanup.

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.

Peter Crosthwaite a7fd6915d8 m25p80.c: Use QOM classes for part differentiation
Currently, M25P80 uses an object property to differentiate between flash parts.
Changed this over to use QOM sub-classes - the actual names of the different parts
are used to create a set of dynamic classes which passes the part info as class
data. The object no longer needs to search the known_devices table for itself,
instead it just gets its info from its own class.

Kept the intermediate class definition private to m25p80.c for the moment, as
the expectation is parts will only be added as new entries in the table. We can
factor out the TYPE_M25P80 abstraction into a header on a demand basis.
