Specifying this bit in the guest CLP response indicates that the guest
can optionally choose to skip translation and instead use
identity-mapped operations.

When receiving a guest mpcifc(4) or mpcifc(6) instruction without the T
bit set, treat this as a request to perform direct mapping instead of
address translation. In order to facilitate this, pin the entirety of
guest memory into the host iommu.
Pinning for the direct mapping case is handled via vfio and its memory
listener. Additionally, ram discard settings are inherited from vfio:
coordinated discards (e.g. virtio-mem) are allowed while uncoordinated
discards (e.g. virtio-balloon) are disabled.
Subsequent guest DMA operations are all expected to be of the format
guest_phys+sdma, allowing them to be used as lookup into the host
iommu table.

PropertyInfo member @type is externally visible via QMP
device-list-properties and qom-list-properies.
Its meaning is not documented at its definition.
It gets passed as @type argument to object_property_add() and
object_class_property_add(). This argument's documentation isn't of
much help, either:
* @type: the type name of the property. This namespace is pretty loosely
* defined. Sub namespaces are constructed by using a prefix and then
* to angle brackets. For instance, the type 'virtio-net-pci' in the
* 'link' namespace would be 'link<virtio-net-pci>'.
The two QMP commands document it as
# @type: the type of the property. This will typically come in one of
# four forms:
#
# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or
# 'double'. These types are mapped to the appropriate JSON
# type.
#
# 2) A child type in the form 'child<subtype>' where subtype is a
# qdev device type name. Child properties create the
# composition tree.
#
# 3) A link type in the form 'link<subtype>' where subtype is a
# qdev device type name. Link properties form the device model
# graph.
"Typically come in one of four forms" followed by three items inspires
the level of trust that is appropriate here.
Clean up a bunch of funnies:
* qdev_prop_fdc_drive_type.type is "FdcDriveType". Its .enum_table
refers to QAPI type "FloppyDriveType". So use that.
* qdev_prop_reserved_region is "reserved_region". Its only user is an
array property called "reserved-regions". Its .set() visits str.
So change @type to "str".
* trng_prop_fault_event_set.type is "uint32:bits". Its .set() visits
uint32, so change @type to "uint32". If we believe mentioning it's
actually bits is useful, the proper place would be .description.
* ccw_loadparm.type is "ccw_loadparm". It's users are properties
called "loadparm". Its .set() visits str. So change @type to
"str".
* qdev_prop_nv_gpudirect_clique.type is "uint4". Its set() visits
uint8, so change @type to "uint8". If we believe mentioning the
range is useful, the proper place would be .description.
* s390_pci_fid_propinfo.type is "zpci_fid". Its .set() visits uint32.
So change type to that, and move the "zpci_fid" to .description.
This is admittedly a lousy description, but it's still an
improvement; for instance, output of -device zpci,help changes from
fid=<zpci_fid>
to
fid=<uint32> - zpci_fid
* Similarly for a raft of PropertyInfo in target/riscv/cpu.c.

Invert the 'no_sdcard' logic, renaming it as the more explicit
"auto_create_sdcard". Machines are supposed to create a SD Card
drive when this flag is set. In many cases it doesn't make much
sense (as boards don't expose SD Card host controller), but this
is patch only aims to expose that nonsense; so no logical change
intended (mechanical patch using gsed).
Most of the changes are:
- mc->no_sdcard = ON_OFF_AUTO_OFF;
+ mc->auto_create_sdcard = true;
Except in
. hw/core/null-machine.c
. hw/arm/xilinx_zynq.c
. hw/s390x/s390-virtio-ccw.c
where the disabled option is manually removed (since default):
- mc->no_sdcard = ON_OFF_AUTO_ON;
+ mc->auto_create_sdcard = false;
- mc->auto_create_sdcard = false;
and in system/vl.c we change the 'default_sdcard' type to boolean.

The general expectation is that header files should follow the same
file/path naming scheme as the corresponding source file. There are
various historical exceptions to this practice in QEMU, with one of
the most notable being the include/qapi/qmp/ directory. Most of the
headers there correspond to source files in qobject/.
This patch corrects most of that inconsistency by creating
include/qobject/ and moving the headers for qobject/ there.
This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h:
scripts/get_maintainer.pl now reports "QAPI" instead of "No
maintainers found".

Booting an s390x VM in record/replay mode hangs due to a deadlock
between rr_cpu_thread_fn() and s390_machine_reset(). The former needs
the record/replay mutex held by the latter, and the latter waits until
the former completes its run_on_cpu() request.
Fix by temporarily dropping the record/replay mutex, like it's done in
pause_all_vcpus().

The problem is that the versioned s390-ccw-virtio machine types
use instance_init() to set global state that should be initialized
before the CPUs get instantiated. But instance_init() is not called
only for the machine that is finally used, it is also called for
temporary instances of objects that are e.g. just created for
introspection. That means that those instance_init() functions can
also be called while a machine (and its CPUs) is already created,
which triggers the assertion in cpu_models.c.
So we must not use instance_init() for setting global state, but
use the machine->init() function instead, which is really only called
once when the machine comes to life.
