Subject: Correct the generation of the `cd 03` instruction
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=4294681d8abd3cd5932352948a62aa5b8dcb8f72;p=people%2Froyger%2Fxen-test-framework.git

Correct the generation of the `cd 03` instruction

Some assemblers "helpfully" turn the two-byte `int $3` into its one-byte form
`int3`.  This defeats the purpose of the test case, so hand-roll the
instrucion.
