Conflicts:
hw/input/stellaris_input.c
The qdev conversion in this pull request ("stellaris-gamepad: Convert
to qdev") eliminates the vmstate_register() call that was converted to
vmstate_register_any() in the conflicting migration pull request.
vmstate_register_any() is no longer necessary now that this device has
been converted to qdev, so take this pull request's version of
stellaris_gamepad.c over the previous pull request's
stellaris_input.c (the file was renamed).

Instead of exposing the ugly hack of how we represent arrays in qdev (a
static "foo-len" property and after it is set, dynamically created
"foo[i]" properties) to boards, add an interface that allows setting the
whole array at once.
Once all internal users of devices with array properties have been
converted to use this function, we can change the implementation to move
away from this hack.

In this mode, the migrate command saves state to a file, allowing one
to quit qemu, reboot to an updated kernel, and restart an updated version
of qemu. The caller must specify a migration URI that writes to and reads
from a file. Unlike normal mode, the use of certain local storage options
does not block the migration, but the caller must not modify guest block
devices between the quit and restart. To avoid saving guest RAM to the
file, the memory backend must be shared, and the @x-ignore-shared migration
capability must be set. Guest RAM must be non-volatile across reboot, such
as by backing it with a dax device, but this is not enforced. The restarted
qemu arguments must match those used to initially start qemu, plus the
-incoming option.

current code sets PCI_SEC_LATENCY_TIMER to RW, but for
pcie to pcie bridges it must be RO 0 according to
pci express spec which says:
This register does not apply to PCI Express. It must be read-only
and hardwired to 00h. For PCI Express to PCI/PCI-X Bridges, refer to the
[PCIe-to-PCI-PCI-X-Bridge] for requirements for this register.
also, fix typo in comment where it's made writeable - this typo
is likely what prevented us noticing we violate this requirement
in the 1st place.

For migration purposes, users might want to reuse the default RAM
backend id, but specify a different memory backend.
For example, to reuse "pc.ram" on q35, one has to set
-machine q35,memory-backend=pc.ram
Only then, can a memory backend with the id "pc.ram" be created
manually.
Let's improve the error message by improving the hint. Use
error_append_hint() -- which in turn requires ERRP_GUARD().

The current implementers of ARI are all SR-IOV devices. The ARI next
function number field is undefined for VF according to PCI Express Base
Specification Revision 5.0 Version 1.0 section 9.3.7.7. The PF still

postcopy_qemufile_src object should be owned by one thread, either the main
thread (e.g. when at the beginning, or at the end of migration), or by the
return path thread (when during a preempt enabled postcopy migration). If
that's not the case the access to the object might be racy.
postcopy_preempt_shutdown_file() can be potentially racy, because it's
called at the end phase of migration on the main thread, however during
which the return path thread hasn't yet been recycled; the recycle happens
in await_return_path_close_on_source() which is after this point.
It means, logically it's posslbe the main thread and the return path thread
are both operating on the same qemufile. While I don't think qemufile is
thread safe at all.
postcopy_preempt_shutdown_file() used to be needed because that's where we
send EOS to dest so that dest can safely shutdown the preempt thread.
To avoid the possible race, remove this only place that a race can happen.
Instead we figure out another way to safely close the preempt thread on
dest.
The core idea during postcopy on deciding "when to stop" is that dest will
send a postcopy SHUT message to src, telling src that all data is there.
Hence to shut the dest preempt thread maybe better to do it directly on
dest node.
This patch proposed such a way that we change postcopy_prio_thread_created
into PreemptThreadStatus, so that we kick the preempt thread on dest qemu
by a sequence of:
mis->preempt_thread_status = PREEMPT_THREAD_QUIT;
qemu_file_shutdown(mis->postcopy_qemufile_dst);
While here shutdown() is probably so far the easiest way to kick preempt
thread from a blocked qemu_get_be64(). Then it reads preempt_thread_status
to make sure it's not a network failure but a willingness to quit the
thread.
We could have avoided that extra status but just rely on migration status.
The problem is postcopy_ram_incoming_cleanup() is just called early enough
so we're still during POSTCOPY_ACTIVE no matter what.. So just make it
simple to have the status introduced.
One flag x-preempt-pre-7-2 is added to keep old pre-7.2 behaviors of
postcopy preempt.
