Memory Binding (0/1)

So I've made a couple attempts at adding a Memory Binding facility to 
the kernel.  Obviously, I've had no success as yet, so I'm stubbornly 
trying another approach! ;)

This patch is just a small pre-patch to the real memory binding.  It 
just adds get_zonelist() and get_node_zonelist() calls, to make some 
code a little more readable.  This patch is super straight-forward.  The 
real fun is in the next patch...
