x86 signals: lift flags diddling code
This lifts the code diddling the TF and DF bits for signal handler setup out of the several places copying the same code into the one place that calls them all. There is no change in what it does. I also separated the recently-added DF bit clearing from the TF diddling. The compiler turns them back into one instruction anyway. The tossing in of DF to the same line of code with no new comments was a bit more arcane than seems wise. Signed-off-by: Roland McGrath <roland@redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
