There is an ugly #ifdef CONFIG_CPU_CAVIUM_OCTEON in the middle of
traps.c.  We can get rid of it if we add a cpu feature for
implementation dependent hwrena bits.  The first patch adds the
feature macro and the second removes the #ifdef by setting the feature
for Octeon.

I will reply with the two patches.

David Daney (2):
 MIPS: Allow CPU specific overriding of CP0 hwrena impl bits.
 MIPS: Move Cavium CP0 hwrena impl bits to cpu-feature-overrides.h
