Pull more powerpc updates from Michael Ellerman:
"Here's some more updates for powerpc for 3.18.
They are a bit late I know, though must are actually bug fixes. In my
defence I nearly cut the top of my finger off last weekend in a
gruesome bike maintenance accident, so I spent a good part of the week
waiting around for doctors. True story, I can send photos if you like :)
Probably the most interesting fix is the sys_call_table one, which
enables syscall tracing for powerpc. There's a fix for HMI handling
for old firmware, more endian fixes for firmware interfaces, more EEH
fixes, Anton fixed our routine that gets the current stack pointer,
and a few other misc bits"

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"

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.

Pull second round of KVM changes from Paolo Bonzini:
"Here are the PPC and ARM changes for KVM, which I separated because
they had small conflicts (respectively within KVM documentation, and
with 3.16-rc changes). Since they were all within the subsystem, I
took care of them.
Stephen Rothwell reported some snags in PPC builds, but they are all
fixed now; the latest linux-next report was clean.
New features for ARM include:
- KVM VGIC v2 emulation on GICv3 hardware
- Big-Endian support for arm/arm64 (guest and host)
- Debug Architecture support for arm64 (arm32 is on Christoffer's todo list)
And for PPC:
- Book3S: Good number of LE host fixes, enable HV on LE
- Book3S HV: Add in-guest debug support
This release drops support for KVM on the PPC440. As a result, the
PPC merge removes more lines than it adds. :)
I also included an x86 change, since Davidlohr tied it to an
independent bug report and the reporter quickly provided a Tested-by;
there was no reason to wait for -rc2"

The 440 target hasn't been properly functioning for a few releases and
before I was the only one who fixes a very serious bug that indicates to
me that nobody used it before either.
Furthermore KVM on 440 is slow to the extent of unusable.
We don't have to carry along completely unused code. Remove 440 and give
us one less thing to worry about.

Pull powerpc updates from Ben Herrenschmidt:
"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),
There is the usual batch of Freescale embedded updates (summary in the
merge commit) and fixes here or there, I think that's it for the
highlights"

The CoreNet Coherency Fabric is part of the memory subsystem on
some Freescale QorIQ chips. It can report coherency violations (e.g.
due to misusing memory that is mapped noncoherent) as well as
transactions that do not hit any local access window, or which hit a
local access window with an invalid target ID.

The driver hasn't been cleaned up and it doesn't look like anyone is
working on it anymore (including the original author). So remove it.
If someone wants to work on cleaning the driver up and moving it out of

In addition, since this removes the CONFIG_NET_VENDOR_SILICOM config
symbol, remove the symbol from all defconfig files that reference it.

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 ..."

This patch introduces the support for Keymile's kmcoge4 board which is
the internal reference design for boards based on Freescale's
P2040/P2041 SoCs. This internal reference design is named kmp204x.
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
The patch also adds a defconfig file for this reference design that is
necessary because of the lowmem option that must be set higher due to
the number of PCIe devices with big ioremapped mem ranges on the boad.

Pull vfs updates from Al Viro:
"The first vfs pile, with deep apologies for being very late in this
window.
Assorted cleanups and fixes, plus a large preparatory part of iov_iter
work. There's a lot more of that, but it'll probably go into the next
merge window - it *does* shape up nicely, removes a lot of
boilerplate, gets rid of locking inconsistencie between aio_write and
splice_write and I hope to get Kent's direct-io rewrite merged into
the same queue, but some of the stuff after this point is having
(mostly trivial) conflicts with the things already merged into
mainline and with some I want more testing.
This one passes LTP and xfstests without regressions, in addition to
usual beating. BTW, readahead02 in ltp syscalls testsuite has started
giving failures since "mm/readahead.c: fix readahead failure for
memoryless NUMA nodes and limit readahead pages" - might be a false
positive, might be a real regression..."

Our netfilter options are stale and important things like masquerading
are no longer enabled. Instead of trying to keep up with any updates,
set CONFIG_NETFILTER_ADVANCED=n on ppc64* and pseries* defconfigs.
This enables the most common netfilter modules for us.
While here, enable the network bridge module which is heavily used in
KVM setups.

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.

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.

Currently all these boards use the same machine struct and also select
