MIPS: Octeon: Add sched_clock() to csrc-octeon.c
...
With the advent of function graph tracing on MIPS, Octeon needs a high
precision sched_clock() implementation. Without it, most timing
numbers are reported as 0.000.
This new sched_clock just uses the 64-bit cycle counter appropriately
scaled.

MIPS: Cavium: Add struct clocksource * argument to octeon_cvmcount_read()
...
This patch modifies parameter of octeon_cvmcount_read() from 'void' to
'struct clocksource *cs', which fixes compile warning for incompatible
parameter type.

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.
