[PATCH] m68knommu: optimized bitops operations for m68knommu
Here is a patch to provide faster bitops for m68knommu, using bset/bclr/bchg
and btst instructions, that do test-and-set on m68k and coldfire processors.
We do thus avoid the need for local_irq_save/local_irq_restore.
Patch original submitted by Philippe De Muyter <phdm@macqel.be>.
