  To: linux-kernel; +Cc: patches, Dave Hansen, corbet, bp, tglx, x86, linux-doc

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 <>

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.

+Code should be tested before submitting to the tip maintainers.  Anything

+comprehensive (and heavyweight) kernel debugging options enabled.
+These debugging options can be found in kernel/configs/x86_debug.config

+	make x86_debug.config
+Some of these options are x86-specific and can be left out when testing
