Thread-topic: [PATCH 0/3][4.17?] x86/pv-shim: ballooning fixes

Hi Andrew and Jan,

Sorry for top posting, I don't really want to block this series so I am answering this on my phone.

I saw Andrew provided his ack, since this series is ported from XenServer and should be included in 4.17.

Thanks for doing this. From our side, they all came from testing where
we took our existing PV guest tests and ran the guests shimmed.

I'm reasonably sure there are more issues lurking, but this is
definitely an improvement on its own.

They want backporting (in due course), so should be considered for 4.17
seeing as they're ready now.
