Since commit 0e4a459f56c32d3e ("tracing: Remove unnecessary DEBUG_FS
dependency"), CONFIG_DEBUG_FS is no longer auto-enabled. This breaks
booting Debian 9, as systemd needs debugfs:
[FAILED] Failed to mount /sys/kernel/debug.
See 'systemctl status sys-kernel-debug.mount' for details.
[DEPEND] Dependency failed for Local File Systems.
...
You are in emergGive root password for maintenance
(or press Control-D to continue):
Fix this by enabling CONFIG_DEBUG_FS explicitly.
See also commit 18977008f44c66bd ("ARM: multi_v7_defconfig: Restore
debugfs support").
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

To be queued as a fix for v5.5.
