Considering the bug we just had with the HAVE_GENERIC_RCU_GUP code,
I'm wondering if people would be willing to look at what it would take
to make x86 use the generic version?
The x86 version of __get_user_pages_fast() seems to be quite similar
to the generic one. And it would be lovely if all the main
architectures shared the same core gup code.
