This helps initramfs builders and other tools to find the full
dependencies of a module.
Debian on powerpc (ppc32) still uses yaboot as default boot loader. Using a
default installation (debian-installer) 64bit and metadata_csum feature are
not setup in ext4. This is discussed in more details at:
https://bugs.debian.org/825110#81
and implemented here:
https://anonscm.debian.org/cgit/d-i/partman-ext3.git/patch/?id=f87dc92157262de1ad8dd3f2343436f08271b4dc
This means that building the kernel as default debian package:
make ARCH=powerpc XYZ_defconfig
make -j8 ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- bindeb-pkg
Will lead to the following boot failure (initramfs prompt):
/dev/sda3: clean, 127679/305216 files, 11128559/1220703 blocks done.
[ 5.592819] EXT4-fs (sda3): Cannot load crc32c driver.
mount: mounting /dev/sda3 on /root failed: No such file or directory
