Currently the Kconfig fragments in kernel/configs and arch/*/configs that aren't used internally aren't discoverable through "make help", which consists of hard-coded lists of config fragments. Instead, list all the fragment targets that have a "# Help: " comment prefix so the targets can be generated dynamically. Add logic to the Makefile to search for and display the fragment and comment. Add comments to fragments that are intended to be direct targets.

# Help: Debugging for CI systems and finding regressions
|
|
#
|
|
# The config is based on running daily CI for enterprise Linux distros to
|
|
# seek regressions on linux-next builds on different bare-metal and virtual
|
|
# platforms. It can be used for example,
|
|
#
|
|
# $ make ARCH=arm64 defconfig debug.config
|
|
#
|
|
# Keep alphabetically sorted inside each section.
|
|
#
