From: Dave Martin <Dave.Martin@arm.com> Since normal execution of any non-branch instruction resets the PSTATE BTYPE field to 0, so do the same thing when emulating a trapped instruction. Branches don't trap directly, so we should never need to assign a non-zero value to BTYPE here. Signed-off-by: Dave Martin <Dave.Martin@arm.com> Signed-off-by: Mark Brown <broonie@kernel.org>
