This series intended to fix (again) a bug that was a subject of the
following change:
6ea6e84 ("KVM: x86: inject exceptions produced by x86_decode_insn")
Suddenly, that fix had a couple mistakes. First, ctxt->have_exception was
not set if fault happened during instruction decoding. Second, returning
value of inject_emulated_instruction was used to make the decision to
reenter guest, but this could happen iff on nested page fault, that is not
the scope where this bug could occur.
However, I have still deep doubts about 3rd commit in the series. Could
you please, make me an advise if it is the correct handling of guest page
fault?
