Chuck Ebbert c22f008ba2 [PATCH] spinlock_debug: don't recompute (jiffies_per_loop * HZ) in spinloop
In spinlock_debug.c, the spinloops call __delay() on every iteration.
Because that is an external function, (jiffies_per_loop * HZ), the loop's
iteration limit, gets recomputed every time.  Caching it explicitly
prevents that.
