6f329468f3 MIPS: Give Octeon+ CPUs their own cputype. 
This allows us to treat them differently at runtime.

e0e53dee69 MIPS: Nuke trailing blank lines 
Recent git versions now warn about those and they've always been a bit of
an annoyance.

63731c964d MIPS: Fix __devinit __cpuinit confusion in cpu_cache_init 
cpu_cache_init and the things it calls should all be __cpuinit instead
of __devinit.

55b8cab49d cpumask: use mm_cpumask() wrapper: mips 
Makes code futureproof against the impending change to mm->cpu_vm_mask.

It's also a chance to use the new cpumask_ ops which take a pointer
(the older ones are deprecated, but there's no hurry for arch code).

631330f584 MIPS: Build fix - include <linux/smp.h> into all smp_processor_id() users. 
Some of the were relying into smp.h being dragged in by another header
which of course is fragile.  <asm/cpu-info.h> uses smp_processor_id()
only in macros and including smp.h there leads to an include loop, so
don't change cpu-info.h.

5b3b16880f MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon. 
These are the rest of the new files needed to add OCTEON processor
support to the Linux kernel.  Other than Makefile and Kconfig which
should be obvious, we have:

csrc-octeon.c   -- Clock source driver for OCTEON.
dma-octeon.c    -- Helper functions for mapping DMA memory.
flash_setup.c   -- Register on-board flash with the MTD subsystem.
octeon-irq.c    -- OCTEON interrupt controller managment.
octeon-memcpy.S -- Optimized memcpy() implementation.
serial.c        -- Register 8250 platform driver and early console.
setup.c         -- Early architecture initialization.
smp.c           -- OCTEON SMP support.
octeon_switch.S -- Scheduler context switch for OCTEON.
c-octeon.c      -- OCTEON cache controller support.
cex-oct.S       -- OCTEON cache exception handler.

asm/mach-cavium-octeon/*.h -- Architecture include files.
