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.

I'm not sure what you mean here ...

Just that I need to keep the DAR fix for dcbX insn in the DTLB handler. If I try
to move it to do_page_fault() I get a lot more DTLB errors for dcbX insn.
