55e5c28502 cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using a
negative offset. Therefore the field is placed last in CPUState.

Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.

Move common parts of mips cpu_state_reset() to mips_cpu_reset().

ce3960ebe5 cpu: Move nr_{cores,threads} fields to CPUState
To facilitate the field movements, pass MIPSCPU to malta_mips_config();
avoid that for mips_cpu_map_tc() since callers only access MIPS Thread

b8bec49ccc dataplane: fix build breakage on set_guest_notifiers()
virtio_pci_set_guest_notifiers() now takes an additional argument to

de0161c0d5 dataplane: handle misaligned virtio-blk requests
O_DIRECT on Linux has alignment requirements on I/O buffers and
misaligned requests result in -EINVAL.  The Linux virtio_blk guest
driver usually submits aligned requests so I forgot to handle misaligned
requests.

It turns out that virtio-win guest drivers submit misaligned requests.
Handle them using a bounce buffer that meets alignment requirements.

The qiov_is_aligned() function checks whether a QEMUIOVector meets a
BlockDriverState's alignment requirements.  This is needed by
virtio-blk-data-plane so:

1. Move the function from block/raw-posix.c to block/block.c.
2. Make it public in block/block.h.
3. Rename to bdrv_qiov_is_aligned().
4. Change return type from int to bool.

b608c8dc02 raw-posix: fix bdrv_aio_ioctl
When the raw-posix aio=thread code was moved from posix-aio-compat.c
to block/raw-posix.c, there was an unintended change to the ioctl code.
The code used to return the ioctl command, which posix_aio_read()
would later morph into a zero.  This hack is not necessary anymore,
and in fact breaks scsi-generic (which expects a zero return code).
Remove it.

cache=writethrough # enable the emulated writethrough semantics for write
cache=directsync # disable cache competely

Guest WCE toggling on the run time to toggle writeback/writethrough is also

There is no reason why for example qemu-ga should include all the
definitions for the QEMU monitor.  However, there are a few
that are needed (qapi_free_SocketAddress, qapi_free_InetSocketAddress,
ErrorClass_lookup).  These should be moved to a separate "core"
.json schema that goes into libqemuutil.a.

For now, make this clearer by moving the qapi-*.o definitions out
of libqemuutil.a.  Once the above refactoring is done, qga-obj-y
should not include anymore qapi-types.o and qapi-visit.o.
