The commit message says "Per the SDM" :) The actual failure case
involves a special code sequence that is exposed in VxWorks guest
testing. Linux does not expose this however.
I see. Is there any chance you could write a testcase for
kvm-unit-tests? Or just explain how to write such a test, and then I
can write it myself; it's not clear to me how the guest can observe the
base and limit of a non-present segment.
