This patchset, on top of my acpi branch, fixes the issues with cross-version migration: - Don't add fw cfg entries when running with -M 1.5 and older - Future proof against future ACPI table changes: create a ROM blob so the tables are migrated (together with BIOS)
With these changes the ACPI generation patchset will become mergeable.
I say *will* since it's only lightly tested, I intend to test properly and re-post the full patchset with acpi table geneation in QEMU ready for merge, next week.
Posting for early flames/review.
