block/pflash_cfi02: Fix memory leak and potential use-after-free
Don't dynamically allocate the pflash's timer. But do use timer_del in
an unrealize function to make sure that the timer can't fire after the
pflash_t has been freed.

hw/arm/virt: Dynamic memory map depending on RAM requirements
Up to now the memory map has been static and the high IO region
base has always been 256GiB.
This patch modifies the virt_set_memmap() function, which freezes
the memory map, so that the high IO range base becomes floating,
located after the initial RAM and the device memory.
The function computes
- the base of the device memory,
- the size of the device memory,
- the high IO region base
- the highest GPA used in the memory map.
Entries of the high IO region are assigned a base address. The
device memory is initialized.
The highest GPA used in the memory map will be used at VM creation
to choose the requested IPA size.
Setting all the existing highmem IO regions beyond the RAM
allows to have a single contiguous RAM region (initial RAM and
possible hotpluggable device memory). That way we do not need
to do invasive changes in the EDK2 FW to support a dynamic
RAM base.
Still the user cannot request an initial RAM size greater than 255GB.

hw/arm/virt: Split the memory map description
In the prospect to introduce an extended memory map supporting more
RAM, let's split the memory map array into two parts:
- the former a15memmap, renamed base_memmap, contains regions below
and including the RAM. MemMapEntries initialized in this array
have a static size and base address.
- extended_memmap, only initialized with entries located after the
RAM. MemMapEntries initialized in this array only get their size
initialized. Their base address is dynamically computed depending
on the the top of the RAM, with same alignment as their size.
Eventually base_memmap entries are copied into the extended_memmap
array. Using two separate arrays however clarifies which entries
are statically allocated and those which are dynamically allocated.
This new split will allow to grow the RAM size without changing the
description of the high IO entries.
We introduce a new virt_set_memmap() helper function which
"freezes" the memory map. We call it in machvirt_init as
memory attributes of the machine are not yet set when
virt_instance_init() gets called.
The memory map is unchanged (the top of the initial RAM still is
256GiB). Then come the high IO regions with same layout as before.

We generally put implicitly defined types in whatever module triggered
their definition. This is wrong for array types, as the included test
case demonstrates. Let's have a closer look at it.
Type 'Status' is defined sub-sub-module.json. Array type ['Status']
occurs in main module qapi-schema-test.json and in
include/sub-module.json. The main module's use is first, so the array
type gets put into the main module.
The generated C headers define StatusList in qapi-types.h. But
include/qapi-types-sub-module.h uses it without including
qapi-types.h. Oops.
To fix that, put the array type into its element type's module.
Now StatusList gets generated into qapi-types-sub-module.h, which all
its users include.

The #include directives to pull in sub-modules use file names relative

include path. Use relative file names instead.
The dummy variable we generate to avoid empty .o files has an invalid

Both messed up in commit 252dc3105fc "qapi: Generate separate .h, .c

- Remove check for s->tx != NULL, because it cannot happen.
- Cache ring->tail in a local variable and use it to check for

because nobody is updating ring->cur and ring->head at that point.

our minimum version requirement to OSX 10.10 Yosemite (released

ui/cocoa: Subclass NSApplication so we can implement sendEvent
When we switch away from our custom event handling, we still want to
be able to have first go at any events our application receives,
because in full-screen mode we want to send key events to the guest,
even if they would be menu item activation events. There are several
ways we could do that, but one simple approach is to subclass
NSApplication so we can implement a custom sendEvent method.
Do that, but for the moment have our sendEvent just invoke the
superclass method.

s390x: Add floating-point extension facility to "qemu" cpu model
The floating-point extension facility implemented certain changes to
BFP, HFP and DFP instructions.
As we don't implement HFP/DFP, we can ignore those completely. Related
to BFP, the changes include
- SET BFP ROUNDING MODE (SRNMB) instruction
- BFP-rounding-mode field in the FPC register is changed to 3 bits
- CONVERT FROM LOGICAL instructions
- CONVERT TO LOGICAL instructions
- Changes (rounding mode + XxC) added to
-- CONVERT TO FIXED
-- CONVERT FROM FIXED
-- LOAD FP INTEGER
-- LOAD ROUNDED
-- DIVIDE TO INTEGER
For TCG, we don't implement DIVIDE TO INTEGER, and it is harder to
implement, so skip that. Also, as we don't implement PFPO, we can skip
changes to that as well. The other parts are now implemented, we can
indicate the facility.
z14 PoP mentions that "The floating-point extension facility is installed
in the z/Architecture architectural mode. When bit 37 is one, bit 42 is
also one.", meaning that the DFP (decimal-floating-point) facility also
has to be indicated. We can ignore that for now.

s390x/tcg: Handle SET FPC AND LOAD FPC 3-bit BFP rounding modes
We already forward the 3 bits correctly in the translation functions. We
also have to handle them properly and check for specification
exceptions.
Setting an invalid rounding mode (BFP only, all DFP rounding modes)
results in a specification exception. Setting unassigned bits in the
fpc, results in a specification exception.
This fixes LOAD FPC (AND SIGNAL), SET FPC (AND SIGNAL). Also for,
SET BFP ROUNDING MODE, 3-bit rounding mode is now explicitly checked.
Note: TCG_CALL_NO_WG is required for sfpc handler, as we now inject
exceptions.
We won't be modeling abscence of the "floating-point extension facility"
for now, not necessary as most take the facility for granted without
checking.

s390x/vfio-ap: Implement hot plug/unplug of vfio-ap device
Introduces hot plug/unplug support for the vfio-ap device.
To hot plug a vfio-ap device using the QEMU device_add command:
(qemu) device_add vfio-ap,sysfsdev=$path-to-mdev
Where $path-to-mdev is the absolute path to the mediated matrix device
to which AP resources to be used by the guest have been assigned.
A vfio-ap device can be hot plugged only if:
1. A vfio-ap device has not been attached to the virtual machine's ap-bus
via the QEMU command line or a prior hot plug action.
2. The guest was started with the CPU model feature for AP enabled
(e.g., -cpu host,ap=on)
To hot unplug a vfio-ap device using the QEMU device_del command:
(qemu) device_del vfio-ap,sysfsdev=$path-to-mdev
Where $path-to-mdev is the absolute path to the mediated matrix device
specified when the vfio-ap device was attached to the virtual machine's
ap-bus.
A vfio-ap device can be hot unplugged only if:
1. A vfio-ap device has been attached to the virtual machine's ap-bus
via the QEMU command line or a prior hot plug action.
2. The guest was started with the CPU model feature for AP enabled
(e.g., -cpu host,ap=on)
Please note that a hot plug handler is not necessary for the vfio-ap device
because the AP matrix configuration for the guest is performed by the
kernel device driver when the vfio-ap device is realized. The vfio-ap device
represents a VFIO mediated device created in the host sysfs for use by a guest.
The mdev device is configured with an AP matrix (i.e., adapters and domains) via
its sysfs attribute interfaces prior to starting the guest or plugging a vfio-ap
device in. When the device is realized, a file descriptor is opened on the mdev
device which results in a callback to the vfio_ap kernel device driver. The
device driver then configures the AP matrix in the guest's SIE state description
from the AP matrix assigned via the mdev device's sysfs interfaces. The AP
devices will be created for the guest when the AP bus running on the guest
subsequently performs its periodic scan for AP devices.
The qdev_simple_device_unplug_cb() callback function is used for the same
reaons; namely, the vfio_ap kernel device driver will perform the AP resource
de-configuration for the guest when the vfio-ap device is unplugged. When the
vfio-ap device is unrealized, the mdev device file descriptor is closed which
results in a callback to the vfio_ap kernel device driver. The device driver
then clears the AP matrix configuration in the guest's SIE state description
and resets all of the affected queues. The AP devices created for the guest
will be removed when the AP bus running on the guest subsequently performs
its periodic scan and finds there are no longer any AP resources assigned to the
guest.

While in the neighbourhood free 'driver' and 'filename' as soon as they are
added to the QDicts. Freeing after the 'done' label doesn't make that much
sense as, if the error path jumps to that label, the values would be NULL
anyway.
This patch also makes that more obvious by taking the error path if
'params' is NULL and then asserting that both driver and filename are
non-NULL in the normal path.
