16 * This is the clock rate of the i8253 PIT. A MIPS system may not have
17 * a PIT by the symbol is used all over the kernel including some APIs.
18 * So keeping it defined to the number for the PIT is the only sane thing

24 * Standard way to access the cycle counter.
25 * Currently only used on SMP for scheduling.
27 * Only the low 32 bits are available as a continuously counting entity.
28 * But this only means we'll force a reschedule every 8 seconds or so,
29 * which isn't an evil thing.
31 * We know that all SMP capable CPUs have cycle counters.
