[Xen-devel] [PATCH for-4.13 0/2] x86/hvm: Multiple corrections to task switch handling

Posted by Andrew Cooper 36 weeks ago
These patches want backporting due to the severity of patch 2.  They should
therefore be considered for 4.13 at this point.

Andrew Cooper (2):
  x86/vtx: Fix fault semantics for early task switch failures
  x86/svm: Write the correct %eip into the outgoing task

Is there a matching XTF test to exercise this functionality?

Thanks, Roger.

Modification of an existing one to begin with (which is how I spotted
the problems).

I don't have a CI-ready test yet.
