Now that the ghes preparation patches were merged, let's add support
for error injection.

I'm opting to fold two patch series into one here:

1. https://lore.kernel.org/qemu-devel/20250113130854.848688-1-mchehab+huawei@kernel.org/

It is the first 5 patches containing changes to the math used to calculate offsets at HEST
table and hardware_error firmware file, together with its migration code. Migration tested
with both latest QEMU released kernel and upstream, on both directions.

There were no changes on this series since last submission, except for a conflict
resolution at the migration table, due to upstream changes.

For more details, se the post of my previous submission.

2. It follows 6 patches from:
	https://lore.kernel.org/qemu-devel/cover.1726293808.git.mchehab+huawei@kernel.org/
    containing the error injection code and script.

   They add a new QAPI to allow injecting GHESv2 errors, and a script using such QAPI
   to inject ARM Processor Error records.

PS.: If I'm counting well, this is the 18th version of this series rebase.

Mauro Carvalho Chehab (11):
  acpi/ghes: Prepare to support multiple sources on ghes
  acpi/ghes: add a firmware file with HEST address
  acpi/ghes: Use HEST table offsets when preparing GHES records
  acpi/generic_event_device: Update GHES migration to cover hest addr
  acpi/generic_event_device: add logic to detect if HEST addr is
    available
  acpi/ghes: add a notifier to notify when error data is ready
  acpi/ghes: Cleanup the code which gets ghes ged state
  acpi/generic_event_device: add an APEI error device
  arm/virt: Wire up a GED error device for ACPI / GHES
  qapi/acpi-hest: add an interface to do generic CPER error injection
  scripts/ghes_inject: add a script to generate GHES error inject
