error compiling committee.c: too many arguments to function

Hmm. This looks bigger than I'd wish for at this point. I'll be offline starting Saturday, so I want -rc3 (on Friday evening) to be in as well-known a state as humanly possible. Which is why I've been pushing back a lot on anything that isn't absolutely essential.

Ok. I've dropped the SRAO patch; this still leaves ~100 changed lines, but they are almost all due to the erratum 383 workaround, which can result in a guest killing the host. The rest of the patches are less critical, but they are one liners and I am comfortable with them in -rc3. The new diffstat also shows no changes to core code:

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.

Ok. Pulled the updated version. Thanks,

Linus
