kvm: nVMX: Allow L1 to intercept software exceptions (#BP and #OF)
commit
ef85b67385436ddc1998f45f1d6a210f935b3388 upstream.
When L2 exits to L0 due to "exception or NMI", software exceptions
(#BP and #OF) for which L1 has requested an intercept should be
handled by L1 rather than L0. Previously, only hardware exceptions
were forwarded to L1.
