This patch introduces the vrange() syscall, which allows for specifying
ranges of memory as volatile, and able to be discarded by the system.
This initial patch simply adds the syscall, and the vma handling

Users of volatile ranges will need to know if memory was discarded.
This patch adds the purged state tracking required to inform userland
when it marks memory as non-volatile that some memory in that range

For 64bit systems we want to use the same binder interface for 32bit and
64bit processes. Thus the size and the layout
for wider discussion.

Hey Thomas, Ingo,
My queue is pretty short (and small) for 3.15, but I wanted to send it

Let me know if you have any feedback or objections.
