One other high-level comment:  It would be nice to see the
arch-independent and x86 portions broken out and explained in their own
right, even if they're small patches.  It's a bit cruel to make us
scroll through a thousand lines of sparc code to see the bits
interesting to us.

It would also be really nice to see a high-level breakdown explaining
what you had to modify, especially since this affects all of the system
calls that take a PROT_* argument.  The sample code is nice, but it's no
substitute for writing it down.

Sure, that is very reasonable. I will do that.

I will expand the explanation in Documentation/sparc/adi.txt.

Thanks!

I think (partially) duplicating that in a cover letter would also be
nice.  The documentation is a bit buried in the 1,000 lines of code.
