Hi Linus,

Hui Tang reported a performance regressions with _TIF_WORK_MASK in
newer kernels, which he tracked to a change that went into 5.11. After
this change, we'll call do_work_pending() more often than we need to,
because we're now testing bits 0..15 rather than just 0..7.

Shuffle the bits around to avoid this.

Please pull!
