Urg no, sorry. I rebased before lunch and then triggered the osstest job. Thanks for committing those two! Roger.
Hello, osstest identified a regression caused by my earlier attempt to fix interrupt injection when using nested VMX. This series aims to fix the regression, and should unblock several osstest branches. The following report is from osstest with this series applied: http://logs.test-lab.xenproject.org/osstest/logs/149051/ Note the last patch (4/4) is the one that actually fixes the issue. Xen will always use the Ack on exit feature so patches 2/4 and 3/4 don't change the functionality when running a nested Xen, as it always requires SVI to be updated. Thanks, Roger.
