.31 - no change, it worked before your patch and it works after.
None of your debugging printks show up. I tried removing the tlbil_va()
from do_dcache_icache_coherency() and userspace goes back to be being
slow/non functional.

top of tree - userspace is slow and unstable, random segfaults,
and none of your debugging printks show up :(

take care!
