Hi Paolo and Radim

Any comments on this patch, I could not find it in 4.13-2 branch.

Please let me know if you want to fix something, or want me to
refresh and resend the patch.

Sorry, I tried it during the merge window, but it didn't pass tests on
VMX and I got distracted by other bugs before looking into the cause.

Can you reproduce the fail?


No worries, thanks.

I can try to reproduce it, are you running kvm-unittest or something different?

IIRC, VMX does not set the gpa_available flag hence I am wondering what did I miss
in the patch to trigger the failure. I will debug it and let you know.
