Commit 171a9bae68 ("staging/octeon: Allow test build on !MIPS") moved
the inclusion of a bunch of headers by various files in the Octeon
ethernet driver into a common header, but in doing so it changed the
order in which those headers are included.
Prior to the referenced commit drivers/staging/octeon/ethernet.c
included asm/octeon/cvmx-pip.h before asm/octeon/cvmx-ipd.h, which makes
use of the CVMX_PIP_SFT_RST definition pulled in by the former. After
commit 171a9bae68 ("staging/octeon: Allow test build on !MIPS") we
pull in asm/octeon/cvmx-ipd.h first & builds fail with:

- boot_mem_map is removed, providing a nice cleanup made possible by the
recent removal of bootmem.
- Some fixes to atomics, in general providing compiler barriers for
smp_mb__{before,after}_atomic plus fixes specific to Loongson CPUs or
MIPS32 systems using cmpxchg64().
- Conversion to the new generic VDSO infrastructure courtesy of Vincenzo
Frascino.
- Removal of undefined behavior in set_io_port_base(), fixing the
behavior of some MIPS kernel configurations when built with recent
clang versions.
- Initial MIPS32 huge page support, functional on at least Ingenic SoCs.
- pte_special() is now supported for some configurations, allowing among
other things generic fast GUP to be used.
- Miscellaneous fixes & cleanups.
And platform specific changes:
- Major improvements to Ingenic SoC support from Paul Cercueil, mostly
enabled by the inclusion of the new TCU (timer-counter unit) drivers
he's spent a very patient year or so working on. Plus some fixes for
X1000 SoCs from Zhou Yanjie.
- Netgear R6200 v1 systems are now supported by the bcm47xx platform.
- DT updates for BMIPS, Lantiq & Microsemi Ocelot systems.

For most OCTEON SoCs there is a repeated and redundant register definition
for almost every hardware register, although the register bit fields
would not differ from other SoCs. Since the driver code should use only
one definition for simplicity, these other fields are just redundant
and can be deleted.
