Defer fail_if()-s as much as possible (in favor of possibly generating exceptions), and avoid generating exceptions when not strictly necessary. Avoid fail_if()-s for simple return code checks (making the code that used them consistent with other, longer existing code). Eliminate redundant generate_exception_if()-s checking lock_prefix (which is already covered by the general check prior to decoding operands). Also fix the testing code to add PROT_EXEC for the mapping that is intended to have instruction executed from. Signed-off-by: Jan Beulich <jbeulich@novell.com>
