It's been a horrible source of confusion and let users to shoot themselves
into both feet with uzis to no end.

and Store Conditional (sc) instructions. More information is
available at <http://www.go-ecs.com/mips/miptek1.htm>.
Say Y here if your CPU has the ll and sc instructions. Say Y here

Say N here for slightly better performance. You must say Y here for
machines which require flushing of write buffers in software. Saying
Y is the safe option; N may result in kernel malfunction and crashes.
