Cool! Thanks for that.

I'm glad to see the supported pagesize enumeration code going into the
kernel. What do you think about committing just that bit to begin
with?

This looks like it touches shared code between mips32 and mips64. I'll
spin this up on a mips24k and mips74k (mips32r2) board soon to see if
it boots fine.

Thanks!
