[PATCH] allow strictatime to be set as a global default

[shentino@gmail.com (Raymond Jennings)]

I'm aware of a little tiff regarding strictatime in the past, and I 
think I came up with a patch that might help everyone get what they 
want.  I'm already using it myself.

I've had some review on #kernelnewbies for technical issues, how does 
this look?
