Thanks, I've applied v6 to qom-next (as usual massaging the commit
messages a bit, in particular extending the last one):
http://repo.or.cz/w/qemu/afaerber.git/shortlog/refs/heads/qom-next
Reasoning:
This series has been around since end of February. v3 fixed a breakage
reported by Anthony (use of signed rather than unsigned visitors); since
then changes were mostly rebasing, and v5/v6 pass make check and my
smoke tests.
While this is not strictly a QOM series, I am picking it as a
prerequisite since Paolo had picked up patches 1, 6, 7 for his Object
properties movement and because patch 1 is handy for newly added
properties such as of the x86 CPU.
Further, Paolo agreed to rebase onto this series.
However, it is my understanding that patches 2 and 4 are independent
bugfixes and as such should go into 1.1.
Luiz, should I send Anthony a PULL for 1.1-rc2 including those two? Can
you ack then? Or do you want to cherry-pick them from qom-next yourself?
