[Xen-devel] [PATCH for-4.13 v2 0/3] x86/hvm: Multiple corrections to task switch handling

Posted by Andrew Cooper 4 years, 4 months 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 (3):
  x86/vtx: Fix fault semantics for early task switch failures
  x86/svm: Always intercept ICEBP
  x86/svm: Write the correct %eip into the outgoing task
