Changes from v1: * Add actual .config fragment instead of just documenting it * Note that these partially x86-specific, but the rest can be used to test all tip contributions. -- From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx> 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.
