I hear you, I can remove DTLB error with an add on patch later if that is OK?
I cannot remove the DARFix though, when I move that to do_page_fault(), I get
duplicate TLB hits on the same insn. It is like when transfer_to_handler()
executes rfi, the cpu restarts the the faulting insn instead of jumping
to the page fault handler, not always but often.
