commit f8b72e7837625c7de569fefcf3bba05ac2ef6b5e
Author: Vladimir Davydov <vdavy...@virtuozzo.com>

Drop vz_compat boot param
It was introduced by commit d7b23ae8a314f ("ve/cgroups: use cgroup
subsystem names only if in vz compat mode") in order to provide a way of
running pcs6 environment along with vz7 kernel. Turned out, this is not
needed, so drop the option altogether.
