Subject: mm: convert vma->vm_flags to 64bit
Benjamin, Hugh, I hope to add your S-O-B to this one because you are original author.
Can I do?
Paul, Russell, This patch modifies arm and sh code a bit. I don't think
they are risky change. but I'm really glad if you see it.
Note: I confirmed x86, power and nommu-arm cross compiler build and
I've got no warning/error.

Subject: [PATCH] mm: convert vma->vm_flags to 64bit
For years, powerpc people repeatedly request us to convert vm_flags
to 64bit. Because now it has no room to store an addional powerpc
specific flags.
Here is previous discussion logs.
http://lkml.org/lkml/2009/10/1/202
http://lkml.org/lkml/2010/4/27/23
But, unforunately they didn't get merged. This is 3rd trial.
I've merged previous two posted patches and adapted it for
latest tree.
Of cource, this patch has no functional change.
