kbuild: Show marked Kconfig fragments in "help" 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 options for tip tree testing
x86/configs: Add x86 debugging Kconfig fragment plus docs The kernel has a wide variety of debugging options to help catch and squash bugs. However, new debugging is added all the time and the existing options can be hard to find. Add a Kconfig fragment with the debugging options which tip maintainers expect to be used to test contributions. This should make it easier for contributors to test their code and find issues before submission.

x86/configs: Update configs in x86_debug.config Commit 4675ff05de2d ("kmemcheck: rip it out") removed kmemcheck and its corresponding build config KMEMCHECK. Commit 0f620cefd775 ("objtool: Rename "VMLINUX_VALIDATION" -> "NOINSTR_VALIDATION"") renamed the debug config option. Adjust x86_debug.config to those changes in debug configs.
