[Xen-devel] [PATCH 1/4] balloon: the balloon driver's proc entry needs CONFIG_PROC_FS

[Horms <horms@xxxxxxxxxxxx>]

balloon: the balloon driver's proc entry needs CONFIG_PROC_FS

CONFIG_PROC_FS is needed in order to compile the proc entry portion
of the baloon driver. I believe that the rest of the driver is still
fully functional with this change.
