Subject: [PATCH v2 2/2] ARM: multi_v7_defconfig: Improve use with systemd

From: Fabio Berton <fabio.berton@...ystems.com.br>

This enables following options:

 - CONFIG_CGROUP_BPF
 - CONFIG_NAMESPACES
 - CONFIG_USER_NS
 - CONFIG_CHECKPOINT_RESTORE
 - CONFIG_BPF_SYSCALL

Those are based on recommendation from Gentoo wiki[1] which describes
the recommended and required kernel options for systemd use.
