[$] What to do in response to a kernel warning

The kernel provides a number of macros internally to allow code to generatewarnings when something goes wrong. It does not, however, provide a lot ofguidance regarding what should happen when a warning is issued. AlexanderPopov recently posted apatch series adding an option for the system's response to warnings;that series seems unlikely to be applied in anything close to its currentform, but it did succeed in provoking a discussion on how warnings shouldbe handled.
