[SPARC64]: Fix build failure when CONFIG_BUG is disabled. When CONFIG_BUG is turned off, the standard trick of: switch (x) { case X: ... case Y: ... default: BUG(); }; to mark impossible cases does not work because BUG() evalutes to nothing and thus GCC just sees a fallthrough code path. Add an explicit KERN_ERR log message and a do_exit() to trap this case. Signed-off-by: David S.
