3.18.91-rt98-rc1 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
We convert all BH_Uptodate_Lock based bit-spinlocks to use
bh_uptodate_lock_irqsave() instead. Those two were introduced after the
initial change in -RT and were not noticed before.
