374b78e370 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.

20b084c4b1 This has been out there long enough, I need to get this in.
This was changed a little bit since my post on Feb 20 (to which
 there were no comments) due to changes I had to work around:
 
 Change b296b664ab "smbus: Add a helper to generate SPD EEPROM
 data" added a function to include/hw/i2c/smbus.h, which I had to move to
 include/hw/smbus_eeprom.h.
 
 There were some changes to hw/i2c/Makefile.objs that I had to fix up.
 
 Beyond that, no changes.
 
 Thanks,

156ac94463 xen-block: stop leaking memory in xen_block_drive_create()
The locally allocated QDict-s need to be freed. ('file_layer' will be
freed implicitly since it is added as an object to 'driver_layer').

Spotted by Coverity: CID 1398649

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.

aab7a3786f hw/arm/armsse: Unify init-svtor and cpuwait handling
At the moment the handling of init-svtor and cpuwait initial
values is split between armsse.c and iotkit-sysctl.c:
the code in armsse.c sets the initial state of the CPU
object by setting the init-svtor and start-powered-off
properties, but the iotkit-sysctl.c code has its own
code setting the reset values of its registers (which are
then used when updating the CPU when the guest makes
runtime changes).

Clean this up by making the armsse.c code set properties on the
iotkit-sysctl object to define the initial values of the
registers, so they always match the initial CPU state,
and update the comments in armsse.c accordingly.

0f862986e0 hw/arm/iotkit-sysctl: Implement CPUWAIT and INITSVTOR*
The CPUWAIT register acts as a sort of power-control: if a bit
in it is 1 then the CPU will have been forced into waiting
when the system was reset (which in QEMU we model as the
CPU starting powered off). Writing a 0 to the register will
allow the CPU to boot (for QEMU, we model this as powering
it on). Note that writing 0 to the register does not power
off a CPU.

For this to work correctly we need to also honour the
INITSVTOR* registers, which let the guest control where the
CPU will load its SP and PC from when it comes out of reset.

52cc6a492b i2c:pm_smbus: Fix pm_smbus handling of I2C block read
The I2C block read function of pm_smbus was completely broken.  It
required doing some direct I2C handling because it didn't have a
defined size, the OS code just reads bytes until it marks the
transaction finished.

This also required adjusting how the AMIBIOS workaround code worked,
the I2C block mode was setting STS_HOST_BUSY during a transaction,
so that bit could no longer be used to inform the host status read
code to start the transaction.  Create a explicit bool for that
operation.

Also, don't read the next byte from the device in byte-by-byte
mode unless the OS is actually clearing the byte done bit.  Just
assuming that's what the OS is doing is a bad idea.

bc15cde0c4 i2c: Don't check return value from i2c_recv()
i2c_recv() cannot fail, so there is no need to check the return
value.  It also returns unt8_t, so comparing with < 0 is not
meaningful.

Fix up various I2C controllers to remove the unneeded code.

f6d4dca807 hw/ppc: Use object_initialize_child for correct reference counting
Both functions, object_initialize() and object_property_add_child() increase
the reference counter of the new object, so one of the references has to be
dropped afterwards to get the reference counting right. Otherwise the child
object will not be properly cleaned up when the parent gets destroyed.
Thus let's use now object_initialize_child() instead to get the reference
counting here right.

The 'dr_phb_enabled' field of that class can be set as part of
machine-specific init code. It will be used to conditionally
enable creation of DRC objects and device-tree description to
facilitate hotplug of PHBs.

Since we can't migrate this state to older machine types,
default the option to true and disable it for older machine
types.

bb2bdd812e spapr: add hotplug hooks for PHB hotplug
Hotplugging PHBs is a machine-level operation, but PHBs reside on the
main system bus, so we register spapr machine as the handler for the
main system bus.

Provide the usual pre-plug, plug and unplug-request handlers.

Move the checking of the PHB index to the pre-plug handler. It is okay
to do that and assert in the realize function because the pre-plug
handler is always called, even for the oldest machine types we support.
