Makes sense.
Alexander - could you please try to add an
unreachable() call in in bug.h and if it
kills the warnings as expected then send
a patch to Arnd including a proper
changelog describing why this was need.
I copied Arnd on this mail albeit he may miss some context...
In short - Alexandar posted a few patches to get rid of
a set of warnings on sparc.
The root cause of the warnings was the definition of
BUG() when CONFIG_BUG is not set.
