# is signed. This doesn't work for package builds which re-use the same build

# directory for every flavour, and the .config may change between flavours.

# So instead of using this script to just sign lib/modules/$KernelVer/extra,

# sign all .ko in the buildroot.

# This essentially duplicates the 'modules_sign' Kbuild target and runs the

# same commands for those modules.
