[Xen-devel] [PATCH 8/8] xen/tmem: Remove the usage of 'noselfballoon', 'selfballoon' and use 'tmem.selfballon' bool instead.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

As the 'tmem' driver is the one that actually sets whether
it will use it or not so might as well make tmem responsible
for this knob.
