[Qemu-devel] [PATCH v3 for-2.9 0/3] q35: add negotiable broadcast SMI

This is v3 of the series, with updates based on the v2 discussion:

I've added feature negotiation via the APM_STS ("scratchpad") register.
A new spec file called "docs/specs/q35-apm-sts.txt" is included.

Tested with new OVMF patches (about to send out those as well).
Regression tested with SeaBIOS (beyond simple functional tests with
maximum SeaBIOS logging enabled, I used gdb to step through the new
ich9_apm_status_changed() callback to see if it was behaving compatibly
with SeaBIOS).

The series was developed and tested on top of v2.7.0, because v2.8.0-rc0
crashes very quickly for me when running OVMF:

  kvm_io_ioeventfd_add: error adding ioeventfd: File exists

It is my understanding that there are patches on the list for this:

  [Qemu-devel] [PATCH v2 for-2.8 0/3] virtio fixes

Anyway, the series rebases to v2.8.0-rc0 without as much as context
