David Gibson e763da2344 pseries: Remove unused callbacks from sPAPR VIO bus state
The original QOMification of the spapr VIO devices in 3954d33 "spapr:
convert to QEMU Object Model (v2)" moved some callbacks from the
VIOsPAPRBus structure to the VIOsPAPRDeviceClass.  Except, that it
forgot to actually remove them from the VIOsPAPRBus structure (which
still exists, though it doesn't fulfill quite the same function as it
did pre-QOM).

This patch removes those now unused callback fields.

	void icp_set_mfrr(ICPState *icp, uint8_t mfrr);
	void icp_eoi(ICPState *icp, uint32_t xirr);

Michael Roth 4bcfa56ca9 spapr_pci: advertise explicit numa IDs even when there's 1 node
With the addition of "numa_node" properties for PHBs we began
advertising NUMA affinity in cases where nb_numa_nodes > 1.

Since the default on the guest side is to make no assumptions about
PHB NUMA affinity (defaulting to -1), there is still a valid use-case
for explicitly defining a PHB's NUMA affinity even when there's just
one node. In particular, some workloads make faulty assumptions about
/sys/bus/pci/<devid>/numa_node being >= 0, warranting the use of
this property as a workaround even if there's just 1 PHB or NUMA
node.

Enable this use-case by always advertising the PHB's NUMA affinity
if "numa_node" has been explicitly set.

We could achieve this by relaxing the check to simply be
nb_numa_nodes > 0, but even safer would be to check
numa_info[nodeid].present explicitly, and to fail at start time
for cases where it does not exist.

This has an additional affect of no longer advertising PHB NUMA
affinity unconditionally if nb_numa_nodes > 1 and "numa_node"
property is unset/-1, but since the default value on the guest
side for each PHB is also -1, the behavior should be the same for
that situation. We could still retain the old behavior if desired,
but the decision seems arbitrary, so we take the simpler route.

Kevin Wolf a92bd191a4 fdc: Move qdev properties to FloppyDrive
This makes the FloppyDrive qdev object actually useful: Now that it has
all properties that don't belong to the controller, you can actually
use '-device floppy' and get a working result.

Command line semantics is consistent with CD-ROM drives: By default you
get a single empty floppy drive. You can override it with -drive and
using the same index, but if you use -drive to add a floppy to a
different index, you get both of them. However, as soon as you use any
'-device floppy', even to a different slot, the default drive is
disabled.

Using '-device floppy' without specifying the unit will choose the first
free slot on the controller.

Max Reitz 48c38e0b8d block/nbd: Add nbd_has_filename_options_conflict()
Right now, we have four possible options that conflict with specifying
an NBD filename, and a future patch will add another one ("address").
This future option is a nested QDict that is flattened at this point,
requiring us to test each option whether its key has an "address."
prefix. Therefore, we will then need to iterate through all options
(including the "export" option which was not covered so far).

Adding this iteration logic now will simplify adding the new option
later. A nice side effect is that the user will not receive a long list
of five options which are not supposed to be specified with a filename,
but we can actually print the problematic option.

Max Reitz 7edca33804 block/nbd: Default port in nbd_refresh_filename()
Instead of not emitting the port in nbd_refresh_filename(), just set it
to the default if the user did not specify it. This makes the logic a
bit simpler.

Max Reitz 442045cbce block/nbd: Reject port parameter without host
Currently, a port that is passed along with a UNIX socket path is
silently ignored. That is not exactly ideal, it should be an error
instead.

Kevin Wolf e5b77eec91 qemu-iotests: Fix typo for NFS with IMGOPTSSYNTAX
Commit 076003f5 added configuration for NFS with IMGOPTSSYNTAX enabled,
but it didn't use the right variable name: $TEST_DIR_OPTS doesn't exist.
This fixes the mistake.

However, this doesn't make anything work that was broken before: The
only way to get IMGOPTSSYNTAX is with -luks, but the combination of
-luks and -nfs doesn't get qemu-img create commands right (because
qemu-img create doesn't support --image-opts yet), so even after this
fix some more work would be required to make the tests pass.

Kevin Wolf 48af776a5b block: Use blk_co_ioctl() for all BB level ioctls
All read/write functions already have a single coroutine-based function
on the BlockBackend level through which all requests go (no matter what
API style the external caller used) and which passes the requests down
to the block node level.

This patch exports a bdrv_co_ioctl() function and uses it to extend this
mode of operation to ioctls.
