WHAT?

The previous value here i386 is 1000 --- so why is the default 250.

Changing the *default* time interrupt frequency in a stable series is
*really* bad idea if you ask me.

Now that this has hit mainline please consider applying:

prompt "Timer frequency"

+ default HZ_1000

Allows the configuration of the timer frequency. It is customary
to have the timer interrupt run at 1000 HZ but 100 HZ may be more
