There isn't any reason to break everything and force updates.  If 
someone wants
a 3G task size, then just configure that with the advanced options.   
All of that
grew out of the embedded board support, so just make PMac support it 
too.
In particular, I don't want to force the 8xx to a 3G task space, 
because it adds
more instructions to the TLB handlers, on a system that has never 
required
such application space.  We are 12 releases in 2.6, and it still seems 
like
a development kernel :-)  I think if someone wants this feature on a 
board
port that doesn't support it, then just fix that one board port instead 
of breaking
everything.

Thanks.
