[PATCH] Fixes, cleanups, compile warning fixes, and documentation update for Xen tmem driver (v2).

[Konrad Rzeszutek Wilk]

Heya,

These nine patches fix the tmem driver to:
 - not emit a compile warning anymore (reported by 0 day test compile tool)
 - remove the various nofrontswap, nocleancache, noselfshrinking, noselfballooning,
   selfballooning, selfshrinking bootup options.
 - said options are now folded in the tmem driver as module options and are
   much shorter (and also there are only four of them now).
 - add documentation to explain these parameters in kernel-parameters.txt
 - And lastly add some logic to not enable selfshrinking and selfballooning
   if frontswap functionality is off.

That is it. Tested and ready to go. If nobody objects will put on my queue
for Linus on Monday.
