Without CONFIG_DEBUG_SPINLOCK configured in I'm getting a large number

subsequent failure at the link stage.
A trivial change to include/linux/spinlock_up.h (i.e. moving the
definition of __raw_read_unlock() outside the ifdef) can get rid of this
warning but I'm not sure that it's the right thing to do as I suspect
this may be an indication of a less trivial problem elsewhere.
Further investigation reveals a number of similar warnings for
__raw_write_unlock() and the following failure in the ipv4 code:
