Any reason we shouldn't do the same thing on ppc32?

Hi,

While ppc64 has the CONFIG_HZ Kconfig option, it wasnt actually being
used. Connect it up and set all platforms to 250Hz.

When I built a 2.6.13-rc7 I got the question about what HZ I wanted,
so I guess we're already doing it. Maybe the default needs changing
though, can't remember what it was.

What were you building for?  I'm wondering if the same issue exists  
that you are asked, but its not wired to actually do anything.

Doh, you're right. No, it's not wired up. I was building for pmac.

Ok, sent a patch to linuxppc-dev for ppc32 which mimic's Anton's  
patch.  Once we get an include/asm-powerpc going we can merge these  
into on file that lives there.
