No, because the machine has a list of issues that keep it from booting a
mainline kernel in a functional state. Once those are cleared up I will
revisit this patch.
The goal was to create a conceptually safe fix for the problem, which
isn't all this hypothetical stuff being discussed, but the fact that the
TLBs are not being flushed properly (with or without the CONT bit stuff)
resulting in a tlb conflict fault long after this code path has finished
executing.
