/*
* This is the frequency of the timer used for Linux's timer interrupt.
* The value should be defined as accurate as possible or under certain
* circumstances Linux timekeeping might become inaccurate or fail.
*
* For many system the exact clockrate of the timer isn't known but due to
* the way this value is used we can get away with a wrong value as long
* as this value is:
*
* - a multiple of HZ
* - a divisor of the actual rate
*
* 500000 is a good such cheat value.
*
* The obscure number 1193182 is the same as used by the original i8254
* time in legacy PC hardware; the chip unfortunately also found in a
* bunch of MIPS systems. The last remaining user of the i8254 for the
* timer interrupt is the RM200; it's a very standard system so there is
* no reason to make this a separate architecture.
* This is the clock rate of the i8253 PIT. A MIPS system may not have
* a PIT by the symbol is used all over the kernel including some APIs.
* So keeping it defined to the number for the PIT is the only sane thing
* for now.
