[PATCH 0/2] MIPS: Use Octeon BBIT instructions in TLB handlers.

[David Daney <ddaney@xxxxxxxxxxxxxxxxxx>]

Octeon has instructions that conditionally branch based on the value
of any single bit in any register.  We use these to reduce the number
of instructions in the generated TLB handlers.

This set applies on top of the recent KScratch patch set.
