21d4e557e2 include/qemu/host-utils.h: Simplify the compiler check in mulu128()
We currently require at least GCC 7.4 or Clang 6.0 for compiling QEMU.
GCC has __builtin_mul_overflow since version 5 already, and Clang 6.0
also provides this built-in function (see its documentation on this page:
https://releases.llvm.org/6.0.0/tools/clang/docs/LanguageExtensions.html ).
So we can simplify the #if statement here.

21b1d97459 main loop: add missing documentation links to GS/IO macros
If we go directly to GLOBAL_STATE_CODE, IO_CODE or IO_OR_GS_CODE
definition, we just find that they "mark and check that the function
is part of the {category} API".
However, ther is no definition on what {category} API is, they are
in include/block/block-*.h
Therefore, add a comment that refers to such documentation.

0882caf4d6 qapi: Add exit-failure PanicAction
Currently QEMU exits with code 0 on both panic an shutdown. For tests
it is useful to return 1 on panic, so that it counts as a test
failure.

Introduce a new exit-failure PanicAction that makes main() return
EXIT_FAILURE. Tests can use -action panic=exit-failure option to
activate this behavior.

b3e6982b41 i386/pc: restrict AMD only enforcing of 1Tb hole to new machine type
The added enforcing is only relevant in the case of AMD where the
range right before the 1TB is restricted and cannot be DMA mapped
by the kernel consequently leading to IOMMU INVALID_DEVICE_REQUEST
or possibly other kinds of IOMMU events in the AMD IOMMU.

Although, there's a case where it may make sense to disable the
IOVA relocation/validation when migrating from a
non-amd-1tb-aware qemu to one that supports it.

Relocating RAM regions to after the 1Tb hole has consequences for
guest ABI because we are changing the memory mapping, so make
sure that only new machine enforce but not older ones.

4876778749 i386/pc: create pci-host qdev prior to pc_memory_init()
At the start of pc_memory_init() we usually pass a range of
0..UINT64_MAX as pci_memory, when really its 2G (i440fx) or
32G (q35). To get the real user value, we need to get pci-host
passed property for default pci_hole64_size. Thus to get that,
create the qdev prior to memory init to better make estimations
on max used/phys addr.

This is in preparation to determine that host-phys-bits are
enough and also for pci-hole64-size to be considered to relocate
ram-above-4g to be at 1T (on AMD platforms).

67f7e426e5 hw/i386: pass RNG seed via setup_data entry
Tiny machines optimized for fast boot time generally don't use EFI,
which means a random seed has to be supplied some other way. For this
purpose, Linux (≥5.20) supports passing a seed in the setup_data table
with SETUP_RNG_SEED, specially intended for hypervisors, kexec, and
specialized bootloaders. The linked commit shows the upstream kernel
implementation.

At Paolo's request, we don't pass these to versioned machine types ≤7.0.

Meanwhile, introduce corresponding hmp commands

"info vcpu_dirty_limit" so the feature can be more usable.

"query-vcpu-dirty-limit" success depends on enabling dirty
page rate limit, so just add it to the list of skipped

c156d5bf2b vdpa: Add device migration blocker
Since the vhost-vdpa device is exposing _F_LOG, adding a migration blocker if
it uses CVQ.

However, qemu is able to migrate simple devices with no CVQ as long as
they use SVQ. To allow it, add a placeholder error to vhost_vdpa, and
only add to vhost_dev when used. vhost_dev machinery place the migration
blocker if needed.

212a300303 lasips2: switch to using port-based IRQs
Now we can implement port-based IRQs by wiring the PS2 device IRQs to the
LASI2Port named input gpios rather than directly to the LASIPS2 device, and
generate the LASIPS2 output IRQ from the int_status bitmap representing the
individual port IRQs instead of the birq boolean.

This enables us to remove the separate PS2 keyboard and PS2 mouse named input
gpios from the LASIPS2 device and simplify the register implementation to
drive the port IRQ using qemu_set_irq() rather than accessing the LASIPS2
device IRQs directly. As a consequence the IRQ level logic in lasips2_set_irq()
can also be simplified accordingly.

For now this patch ignores adding the int_status bitmap and simply drops the
birq boolean from the vmstate_lasips2 VMStateDescription. This is because the
migration stream is already missing some required LASIPS2 fields, and as this
series already introduces a migration break for the lasips2 device it is
easiest to fix this in a follow-up patch.
