Was the immediately previous linux-next behaving correctly?
If so, nothing has changed in the ARM32 kernel tree, so this must be someone else's issue - code that someone else has pushed into linux-next.
It looks to me like someone is walking the page tables incorrectly, somewhere buried in handle_mm_fault(), because the PTE pointer is in the upper-2k of a 4k page, which is most definitely illegal on arm32.
