Ugh. I switched that __io() define to the __typesafe_io(), but
forgot to remove the __io function.
Thanks for noticing! Updated patch below.

ARM: cns3xxx: Add basic support for Cavium Networks CNS3xxx processors
This patch adds very basic support for ECONA CNS3xxx ARM11 MPcore
(ARMv6) dual-core processors.
Note that SMP is not yet supported, as well as many peripheral
devices. Support for these features will be added later.
