Cover letter [PATCH 0/3] x86/vm86/32: A bugfix and a matching test improvement
A patch in 4.2 broke vm86's POPF emulation in a way that was somehow subtle enough that no one noticed until now. Fix it and improve the test case to exercise the code.
(The improved test case also exercises some code paths that were *not*
broken but that would have become broken if Stas' original suggested patch were applied. Go testing!)
