- All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.

* This is the frequency of the timer used for Linux's timer interrupt.

* 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

|

|
|
* - a multiple of HZ
|
|
* - a divisor of the actual rate
