Pull powerpc updates from Michael Ellerman:
"Here's a first pull request for powerpc updates for 3.18.
The bulk of the additions are for the "cxl" driver, for IBM's Coherent
Accelerator Processor Interface (CAPI). Most of it's in drivers/misc,
which Greg & Arnd maintain, Greg said he was happy for us to take it
through our tree.
There's the usual minor cleanups and fixes, including a bit of noise
in drivers from some of those. A bunch of updates to our EEH code,
which has been getting more testing. Several nice speedups from
Anton, including 20% in clear_page().
And a bunch of updates for freescale from Scott"

Freescale updates from Scott (27 commits):
"Highlights include DMA32 zone support (SATA, USB, etc now works on 64-bit
FSL kernels), MSI changes, 8xx optimizations and cleanup, t104x board
support, and PrPMC PCI enumeration."
It pulls in more code, including causing us to build a relocatable
kernel, which is good for testing.
The resulting kernel is still usable as a non-crash dump kernel.

Because powernv arrived after these other platforms, the defconfigs
didn't have PPC_POWERNV disabled, and being default y it gets turned on.
If we're going to bother having defconfigs for the specific platforms
then they should only build the code required for those platforms.
The grab bag of everything config is ppc64_defconfig.

"This is the powerpc new goodies for 3.17. The short story:
The biggest bit is Michael removing all of pre-POWER4 processor
support from the 64-bit kernel. POWER3 and rs64. This gets rid of a
ton of old cruft that has been bitrotting in a long while. It was
broken for quite a few versions already and nobody noticed. Nobody
uses those machines anymore. While at it, he cleaned up a bunch of
old dusty cabinets, getting rid of a skeletton or two.
Then, we have some base VFIO support for KVM, which allows assigning
of PCI devices to KVM guests, support for large 64-bit BARs on
"powernv" platforms, support for HMI (Hardware Management Interrupts)
on those same platforms, some sparse-vmemmap improvements (for memory
hotplug),

Pull powerpc updates from Ben Herrenschmidt:
"Here is the bulk of the powerpc changes for this merge window. It got
a bit delayed in part because I wasn't paying attention, and in part
because I discovered I had a core PCI change without a PCI maintainer
ack in it. Bjorn eventually agreed it was ok to merge it though we'll
probably improve it later and I didn't want to rebase to add his ack.
There is going to be a bit more next week, essentially fixes that I
still want to sort through and test.
The biggest item this time is the support to build the ppc64 LE kernel
with our new v2 ABI. We previously supported v2 userspace but the
kernel itself was a tougher nut to crack. This is now sorted mostly
thanks to Anton and Rusty.
We also have a fairly big series from Cedric that add support for
64-bit LE zImage boot wrapper. This was made harder by the fact that
traditionally our zImage wrapper was always 32-bit, but our new LE
toolchains don't really support 32-bit anymore (it's somewhat there
but not really "supported") so we didn't want to rely on it. This
meant more churn that just endian fixes.
This brings some more LE bits as well, such as the ability to run in
LE mode without a hypervisor (ie. under OPAL firmware) by doing the
right OPAL call to reinitialize the CPU to take HV interrupts in the
right mode and the usual pile of endian fixes.
There's another series from Gavin adding EEH improvements (one day we
*will* have a release with less than 20 EEH patches, I promise!).
Another highlight is the support for the "Split core" functionality on
P8 by Michael. This allows a P8 core to be split into "sub cores" of
4 threads which allows the subcores to run different guests under KVM
(the HW still doesn't support a partition per thread).
And then the usual misc bits and fixes ..."

The peripherals used on this board are:
- SPI NOR Flash as bootloader medium
- NAND Flash with a ubi partition
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 4 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
CPLD
- 2 I2C busses
- last but not least, the mandatory serial port

This processor/memory module was mostly used on ATCA blades and
before that, on cPCI blades. It wasn't really user friendly, with
custom non u-boot bootloaders (powerboot/motload) and no real way
to recover corrupted boot flash (which was a common problem).
As such, it had its day back before the big ppc --> powerpc move
to device trees, and that was largely through commercial BSPs that
started to dry up around 2007.
Systems using one were largely in a "deploy and sustain" mode,
so interest in upgrading to new kernels in the field was nil.
Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA
chassis largely rules out any hobbyist/enthusiast interest.
The point of all this, is that we might as well delete the in
kernel files relating to this platform. No point in continuing
to build it via walking the defconfigs or via linux-next testing.

This patch removes CONFIG_MTD_PARTITIONS in config files for powerpc.
Because CONFIG_MTD_PARTITIONS was removed by commit 6a8a98b22b.

This makes ppc64_defconfig bootable without initrd on pasemi systems,
most of whom have MV SATA controllers. Some have SIL24, but that driver
is already enabled.

Add support for the Motorola/Emerson MVME5100 Single Board Computer.
The MVME5100 is a 6U form factor VME64 computer with:
- A single MPC7410 or MPC750 CPU
- A HAWK Processor Host Bridge (CPU to PCI) and
MultiProcessor Interrupt Controller (MPIC)
- Up to 500Mb of onboard memory
- A M48T37 Real Time Clock (RTC) and Non-Volatile Memory chip
- Two 16550 compatible UARTS
- Two Intel E100 Fast Ethernets
- Two PCI Mezzanine Card (PMC) Slots
- PPCBug Firmware
The HAWK PHB/MPIC is compatible with the MPC10x devices.
There is no onboard disk support. This is usually provided by installing a PMC
in first PMC slot.
This patch revives the board support, it was present in early 2.6
series kernels. The board support in those days was by Matt Porter of
MontaVista Software.
CSC Australia has around 31 of these boards in service. The kernel in use
for the boards is based on 2.6.31. The boards are operated without disks
from a file server.
This patch is based on linux-3.13-rc2 and has been boot tested.
Only boards with 512 Mb of memory are known to work.

mpc85xx_smp_defconfig and mpc85xx_defconfig already have CONFIG_P1023RDS=y.
Merge CONFIG_P1023RDB=y and other relevant configurations into
mpc85xx_smp_defconfig and mpc85_defconfig.

The bestcomm driver has been moved to drivers/dma, so to select
this driver by default additionally CONFIG_DMADEVICES has to be
enabled. Currently it is not enabled in the config despite existing
CONFIG_PPC_BESTCOMM=y in the config files. Fix it.

During "make ppc6xx_defconfig" the following happens:
HOSTCC scripts/basic/fixdep
GEN /usr/local/src/tmp/lnx/Makefile
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/zconf.tab.o

arch/powerpc/configs/ppc6xx_defconfig:74:warning: symbol value 'm' invalid for MCU_MPC8349EMITX
Setting CONFIG_MCU_MPC8349EMITX=y in ppc6xx_defconfig makes the warning
go away. This too has been reported by Geert Uytterhoeven a long time ago:

Currently all these boards use the same machine struct and also select
the same kernel options, so it seems a bit of redundant to keep one
separate kernel option for each board. Also update the defconfigs
according to this change.
