Revert "sched, x86: Optimize branch hint in __switch_to()"
This reverts commit a3a1de0c34de6f5f8332cd6151c46af7813c0fcb. Commit 8ec6993d9f7d961014af970ded57542961fe9ad9 cleared the es and ds selectors, so the original branch hints are correct now. Therefore the branch hint doesn't need to be removed. Signed-off-by: Tim Blechmann <tim@klingt.org> LKML-Reference: <4B16503A.8030508@klingt.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
