From: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> [ Upstream commit fa2cdb1762d15f701b83efa60b04f0d04e71bf89 ] 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").
