Since last time: - Split out KVM parts. Technically they don't actually have dependencies with the Linux patches I suppose, so they could be merged via different trees. Logically I think they are better to stay together.
- Fix and simplify the KVM secondary thread management patch, thanks Gautham. - Fixed a bug in the ESL=0 avoid overhead patch. - Retested on P8 and P9 with qemu. - Mambo simulator still doesn't handle EC=0 wakeups properly, but I have reported that, and managed to write a patch here to fix the simulator bug and test there too.
