Pull MIPS updates from Ralf Baechle:
- three fixes for 3.15 that didn't make it in time
- limited Octeon 3 support.
- paravirtualization support
- improvment to platform support for Netlogix SOCs.
- add support for powering down the Malta eval board in software
- add many instructions to the in-kernel microassembler.
- add support for the BPF JIT.
- minor cleanups of the BCM47xx code.
- large cleanup of math emu code resulting in significant code size
reduction, better readability of the code and more accurate
emulation.
- improvments to the MIPS CPS code.
- support C3 power status for the R4k count/compare clock device.
- improvments to the GIO support for older SGI workstations.
- increase number of supported CPUs to 256; this can be reached on
certain embedded multithreaded ccNUMA configurations.
- various small cleanups, updates and fixes

Add support for the XLP5XX processor which is an 8 core variant of the
XLP9XX. Add XLP5XX cases to code which earlier handled XLP9XX.

The existing code is buggy because built-in DTBs are in init memory.
It is also broken because the reserved bootmem was then freed after
unflattening, but the unflattened tree points to data in the flat tree.
Fix this by using the unflatten_and_copy_device_tree function.
This removes all accesses to FDT header data by the arch code.

Add a default device tree fie for XLP9XX boards, and add code to use
this device tree if no DTB is passed to the kernel.

The early_init_devtree() API was removed in linux-next for 3.13 with
commit "mips: use early_init_dt_scan". This causes Netlogic XLP compile
to fail:
arch/mips/netlogic/xlp/setup.c:101: undefined reference to `early_init_devtree'
Add xlp_early_init_devtree() which uses the __dt_setup_arch() to
handle early device tree related initialization to fix this.
