Subject: [PATCH][MIPS] kernel build fails if CONFIG_KGDB=y and CONFIG_SMP=n

From: Frank Rowand <[email-masked]>

The kernel build fails if CONFIG_KGDB=y and CONFIG_SMP=n.

kgdb_wait() is defined but unused, resulting in a warning.
The warning is converted to an error by the
"EXTRA_CFLAGS += -Werror" in arch/mips/kernel/Makefile.
