The 8xx properly implements copy-on-write now. I don't remember when
I updated this, maybe somewhere in the mid 2.3.xxx timeframe. All of
the processor specific MM functions have to be changed, it isn't
something that is likely going to be a configuration option. due to
all of the common #define, macros, and page table functions. It
does remove three instructions and a branch from the TLBmiss handler :-)
