I've reviewed these and they look sane and safe for 2.0.
mst, could you have a second look as PC maintainer and take them?

Thanks, this is more than I would've done myself or asked for. I've
re-broken the text paragraphs of 4/7 to fit into 76 chars and filled in
the commit info in 7/7:
https://github.com/afaerber/qemu-cpu/commits/qom-next

And for the record, this demonstrates how pretty much any I2C device
(such as ds1338) can be tested for lack of other libqos drivers: Add it
via -device to n800 or n810 machine using a free address (such as 0x49
here) and give the device an ID for accessing it via
/machine/peripheral/<id> (just shorthand <id> here, I let that slip
through).

This diffstat luckily differs from the patches. Please double-check your
setup. :)
