I like these patches, no objections.

BTW. I had been even toying with allocating the struct vm_fault structure
further up, and filling in various bits as we we call down. Haven't put
much time into that, but this patch goes one step toward that.. but
arguably this patch is most useful because it allows more "flags" to be
passed down.  Probably not much more flexibility can be gained from
passing down the rest of the vm_fault structure (but I might still try
it again in the hope of a readability improvement).
