ccb084d3f0 s390: new contributions GPLv2 or later
IBMs s390 contributions were meant to to be gplv2 or later (since
we were contributing to qemu). Several of the s390 specific files
link to gpl code anyway, so lets clarify the licence statement for
new contributions for those files that we have touched multiple
times or will likely touch again.

This patch does not touch files that mostly deal with tcg.

e49798b1bd openpic: export e500 epr enable into a ppc.c function
Enabling and disabling the EPR capability (mpic_proxy) is a system
wide operation. As such, it belongs into the ppc.c file, since that's
where PPC specific machine wide logic happens.

b8dec1443e PPC: e500: Change in-memory order of load blobs
Today, we load

  <kernel> <initrd> <dtb>

into memory in that order. However, Linux has a bug where it can only
handle the dtb if it's within the first 64MB of where <kernel> starts.

So instead, let's change the order to

  <kernel> <dtb> <initrd>

making Linux happy.

746a870b3c PPC: Provide zero SVR for -cpu e500mc and e5500
Even though our -cpu types for e500mc and e5500 are no real CPUs that
actually have version registers, a guest might still want to access
said version register and that has to succeed for a guest to be happy.

So let's expose a zero SVR value on E500_SVR SPR reads.

528e536ea2 PPC: E500: Calculate loading blob offsets properly
We have 3 blobs we need to load when booting the system:

  - kernel
  - initrd
  - dtb

We place them in physical memory in that order. At least we should.
This patch fixes the location calculation up to take any module into
account, fixing the dtb offset along the way.

cf139388ad dataplane: support viostor virtio-pci status bit setting
The viostor virtio-blk driver for Windows does not use the
VIRTIO_CONFIG_S_DRIVER bit.  It only sets the VIRTIO_CONFIG_S_DRIVER_OK
bit.

The viostor driver refreshes the virtio-pci status byte sometimes while
the guest is running.  We misinterpret 0x4 (VIRTIO_CONFIG_S_DRIVER_OK)
as an indication that virtio-blk-data-plane should be stopped since 0x2
(VIRTIO_CONFIG_S_DRIVER) is missing.  The result is that the device
becomes unresponsive.

cd7fdfe59f dataplane: avoid reentrancy during virtio_blk_data_plane_stop()
When dataplane is stopping, the s->vdev->binding->set_host_notifier(...,
false) call can invoke the virtqueue handler if an ioeventfd
notification is pending.  This causes hw/virtio-blk.c to invoke
virtio_blk_data_plane_start() before virtio_blk_data_plane_stop()
returns!

The result is that we try to restart dataplane while trying to stop it
and the following assertion is raised:

  msix_set_mask_notifier: Assertion `!dev->msix_mask_notifier' failed.

Although the code was intended to prevent this scenario, the s->started
boolean isn't enough.  Add s->stopping so that we can postpone clearing
s->started until we've completely stopped dataplane.

This way, virtqueue handler calls during virtio_blk_data_plane_stop()
are ignored.  When dataplane is legitimately started again later we
already self-kick ourselves to resume processing.

2ea9b58f0b aio: Fix return value of aio_poll()
aio_poll() must return true if any work is still pending, even if it
didn't make progress, so that bdrv_drain_all() doesn't stop waiting too
early. The possibility of stopping early occasionally lead to a failed
assertion in bdrv_drain_all(), when some in-flight request was missed
and the function didn't really drain all requests.

In order to make that change, the return value as specified in the
function comment must change for blocking = false; fortunately, the
return value of blocking = false callers is only used in test cases, so
this change shouldn't cause any trouble.

Function leul_to_cpu() is only used in kvm-all.c, so the warnings
