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.
