I did too and it results into the patchset I'm going to send.

Basically it removes all arrays from the init.data section and make
them automatic variables. So it's pretty extreme and maybe if the
stack pressure is too high, we could balance it. This is done by patch
2,3,4.

   text    data     bss     dec     hex filename
   9840    3904    1568   15312    3bd0 arch/mips/mm/tlbex.o~before
   9776     576    1568   11920    2e90 arch/mips/mm/tlbex.o~after

While I was at it, I did some trivial cleanups witch patch 1,5,6.

Thanks,
