Moving mac68k to 8K pages?

[John Klos <john%ziaspace.com@localhost>]

Hi, m68k Mac fans,

After thinking about Izumi's recommendation to increase m68k usable 
address space by increasing the page size from 4K to 8K, I decided to give 
it a try on mac68k.

On a Quadra 605 which has 132 megs of memory I could reliably panic the 
machine by trying to compile any of a number of different packages from 
pkgsrc. After switching to 8K, this Quadra has been compiling for 22 days 
straight without a panic.

I expect this will help with machines with even more memory. I have a 
Quadra 630 with 196 megs and a quadra 610 with 260 megs, plus soon a 
Quadra 800 with 520 megs.

Are there any good reasons to not switch mac68k to 8K pages, at very least 
until someone gets around to rewriting the PMAP?
