The first removes the SA_ entries and replaces with
equivalent #defined 
constant.

Where does one get these patches and how does one apply them
(the Nvidia is 
closed driver .run file which includes compressed sources
inside. The rt8 
patch is a patch file, not a collection of source.

BTW: I did not run into any pagefault_disable undefined
symbols anywhere to my 
recollection. As I said, the rt8 patch had no business
removing the SA_ 
defines (Linus has not done this yet!).

there is an option to extract the .run archive only.
--extract-only
maybe. Then apply your patches and compile the driver from
within the
source tree.

I doubt the -rt developers care about closed source drivers.
 It's up
to nvidia to fix their code to work with -rt.
