There exist systems other than PARISC where MDWE may not be feasible to support; rather than cluttering up the generic code with additional arch-specific logic let's add a generic function for checking MDWE support and allow each arch to override it as needed.

PA-RISC folk need to ack/review-by this patch. Alternatively, it needs to be restructured to add the arch_memory_deny_write_exec_supported() override without touching the PA-RISC code, which then makes the Arm patch independent of the status of the PA-RISC patch. That will allow the Arm issue to be solved even if an ack is not forthcoming for the PA-RISC parts.
Alternatively, I wonder whether akpm would be willing to pick up this patch set as-is.
