I modified the mips pmap to drop into ddb if there was an attempt to map a page
with an incorrect page color (color(VA) != color(PA)). Then using UVMHIST I
fixed each cause. I can now boot a kernel on my matt-nb5-mips64 branch into
sysinst with no bad color matches. I'm sure I haven't found
What happens if loaning is done?

I've now fixed socket loaning and pipe loaning to do the right thing.

(4 colors for its Icache and 2 colors for its Dcache)
so this is important to me.
VCEI/VCED handlers on R4400 would also be useful to catch aliases.
