The following text from the original cover letter still serves as an
introduction to the series:
"Currently we treat the shared_info page as guest memory and the VMM
informs KVM of its location using a GFN. However it is not guest memory as
such; it's an overlay page. So we pointlessly invalidate and re-cache a
mapping to the *same page* of memory every time the guest requests that
shared_info be mapped into its address space. Let's avoid doing that by
modifying the pfncache code to allow activation using a fixed userspace HVA
as well as a GPA."
This version of the series is functionally the same as version 6. I have
simply added David Woodhouse's R-b to patch 11 to indicate that he has
now fully reviewed the series.
Thanks. I believe Sean is probably waiting for us to stop going back
and forth, and for the dust to settle. So for the record: I think I'm
done heckling and this is ready to go in.
Nudge.
Sean, is there anything more I need to do on this series?
