7011baece2 usb: remove unnecessary NULL device check from usb_ep_get()
No caller of usb_ep_get() calls it with a NULL device (previous commits
have addressed the few remaining cases which didn't explicitly check).
Replace check for 'dev == NULL' with an assert instead.

if it doesn't find a device matching 'addr' so explicitly check

92cf34279c xhci: add asserts to help with static code analysis
Most callers of xhci_port_update() and xhci_wakeup() pass in a pointer
to an array entry and can never be NULL but add two defensive asserts
to protect against future changes (e.g. adding a new port speed, etc.)

return of a NULL XHCIPort.

56090d78a7 usb: rearrange usb_ep_get()
There is no need to calculate the 'eps' variable in usb_ep_get()
if 'ep' is the control endpoint.  Instead the calculation should
be done after validating the input before returning an entry
indexed by the endpoint 'ep'.

0a6c86d024 blockdev: acquire aio_context for bitmap add/remove
When bitmaps are persistent, they may incur a disk read or write when bitmaps
are added or removed. For configurations like virtio-dataplane, failing to
acquire this lock will abort QEMU when disk IO occurs.

We used to acquire aio_context as part of the bitmap lookup, so re-introduce
the lock for just the cases that have an IO penalty. Commit 2119882c removed
these locks, and I failed to notice this when we committed fd5ae4cc, so this
has been broken since persistent bitmaps were introduced.

f67cf661f8 dirty-bitmap: Expose persistent flag to 'query-block'
Since qemu currently doesn't flush persistent bitmaps to disk until
shutdown (which might be MUCH later), it's useful if 'query-block'
at least shows WHICH bitmaps will (eventually) make it to persistent
storage.  Update affected iotests.

183e4281a3 qapi: move RTC_CHANGE to the target schema
A few targets don't emit RTC_CHANGE, we could restrict the event to
the tagets that do emit it.

Note: There is a lot more of events & commands that we could restrict
to capable targets, with the cost of some additional complexity, but
the benefit of added correctness and better introspection.

9d7b70864a qmp: Deprecate query-events in favor of query-qmp-schema
query-events doesn't reflect compile-time configuration.  Instead of
fixing that, deprecate the command in favor of query-qmp-schema.

Libvirt prefers query-qmp-schema as of commit 22d7222ec0 "qemu: caps:
Don't call 'query-events' when we probe events from QMP schema".
It'll be in the next release.

093e367951 Revert "qapi-events: add 'if' condition to implicit event enum"
This reverts commit 7bd2634905.

The commit applied the events' conditions to the members of enum
QAPIEvent.  Awkward, because it renders QAPIEvent unusable in
target-independent code as soon as we make an event target-dependent.
Reverting this has the following effects:

* ui/vnc.c can remain target independent.

* monitor_qapi_event_conf[] doesn't have to muck around with #ifdef.

* query-events again doesn't reflect conditionals.  I'm going to
  deprecate it in favor of query-qmp-schema.

Another option would be to split target-dependent parts off enum
QAPIEvent into a target-dependent enum.  Doesn't seem worthwhile right
now.

The introspection data is statically generated once, and must thus be
built per-target to reflect target-specific configuration.

Drop "do_test_visitor_in_qmp_introspect(&qmp_schema_qlit)" since the
schema is no longer in a common object. It is covered by the per-target
query-qmp-schema test instead.

dcac64711e qapi: Clean up modular built-in code generation a bit
We neglect to call .visit_module() for the special module we use for
built-ins.  Harmless, but clean it up anyway.  The
tests/qapi-schema/*.out now show the built-in module as 'module None'.

Subclasses of QAPISchemaModularCVisitor need to ._add_module() this
special module to enable code generation for built-ins.  When this
hasn't been done, QAPISchemaModularCVisitor.visit_module() does
nothing for the special module.  That looks like built-ins could
accidentally be generated into the wrong module when a subclass
neglects to call ._add_module().  Can't happen, because built-ins are
all visited before any other module.  But that's non-obvious.  Switch
off code generation explicitly.

Rename QAPISchemaModularCVisitor._begin_module() to
._begin_user_module().

New QAPISchemaModularCVisitor._is_builtin_module(), for clarity.

09ced81aac s390x: always provide pci support
We tried to make pci support optional on s390x in the past;
unfortunately, we still require the s390 phb to be created
unconditionally due to backwards compatibility issues.

Instead of sinking more effort into this (including compat
handling for older machines etc.) for non-obvious gains, let's
just make CONFIG_PCI something that is always set on s390x.

Note that you can still fence off pci for the _guest_ if you
provide a cpu model without the zpci feature.

44699e1c94 s390x: Fix the confusing contributions-after-2012 license statements
The license information in these files is rather confusing. The text
declares LGPL first, but then says that contributions after 2012 are
licensed under the GPL instead. How should the average user who just
downloaded the release tarball know which part is now GPL and which
is LGPL?

Looking at the text of the LGPL (see COPYING.LIB in the top directory),
the license clearly states how this should be done instead:

"3. You may opt to apply the terms of the ordinary GNU General Public
 License instead of this License to a given copy of the Library. To do
 this, you must alter all the notices that refer to this License, so
 that they refer to the ordinary GNU General Public License, version 2,
 instead of to this License."

Thus let's clean up the confusing statements and use the proper GPL
text only.
