Merge tag 'tif-notify-signal-2023-01-06' of git://git.kernel.dk/linux
Pull arm TIF_NOTIFY_SIGNAL fixup from Jens Axboe:
"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"
