Re: [PATCH] Really start using the page walking API

Hi all,

here come some improvements of the page walking API code.

First: make_pages_present() would do an infinite recursion, if
   used in find_extend_vma(). I fixed this. Might as well have
   caused the ntp crash, that has been observed. 
   So these make_pages_present parts are really important.

I also did the promised rewrite of make_pages_present() and its
users.

MM-Gurus: Please double check, that I always provide the right vma.

I also did two sample implementations (Kai and Doug, this is why
you are CC'ed) of the scatter list walking and removed ~100
lines of code while doing it.

Ingo,
I see that Andrew has put this patch in 2.5.49-mm2 and seems
to be asking for testers. So I will try and test sg's usage.
[It is a while since I built in sg (and other drivers) but
working modules has been very frustrating since 2.5.48 ...]
