The DART table allocation is registered to kmemleak via the
memblock_alloc_base() call. However, the DART table is later unmapped
and dart_tablebase VA no longer accessible. This patch tells kmemleak
not to scan this block and avoid an unhandled paging request.

This patch enables POWER8 doorbell IPIs on powernv.
Since doorbells can only IPI within a core, we test to see when we can use
doorbells and if not we fall back to XICS. This also enables hypervisor
doorbells to wakeup us up from nap/sleep via the LPCR PECEDH bit.
Based on tests by Anton, the best case IPI latency between two threads dropped
from 894ns to 512ns.

git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
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 ..."

There is now a way to ensure all platform devices get a unique name when
populated from the device tree, and the DCR_NATIVE code path is broken
anyway. PowerPC Cell (PS3) is the only platform that actually uses this
path. Most likely nobody will notice if it is killed. Remove the code
and associated ugly #ifdef.
The user-visible impact of this patch is that any DCR device on Cell
will get a new name in the /sys/devices hierarchy.

Parsing and registration of fixed PHY devices was needed with the use of
of_phy_connect_fixed_link() because this function was using the
designated PHY address identifier (first cell of the property) as the
address to bind the PHY on the emulated bus.
Since commit 3be2a49e5c08d268f8af0dd4fe89a24ea8cdc339 ("of: provide a
binding for fixed link PHYs") a new pair of functions has been
introduced which allows for dynamic address allocation of these fixed
PHY devices, but also parses the old 'fixed-link' 5-digit property.
Registration of fixed PHY early in platform code was needed because we
could not issue a fixed MDIO bus re-scan within network drivers. The
fixed PHYs had to be registered before the network drivers would call
of_phy_connect_fixed_link(). All of these caveats are solved now, such
that we can safely remove of_add_fixed_phys() now.

Several of the error paths from fsl_rio_setup are missing error
messages.
Worse, fsl_rio_setup initializes several global pointers and does not
NULL them out after freeing/unmapping on error. This caused
fsl_rio_mcheck_exception() to crash when accessing rio_regs_win which
was non-NULL but had been unmapped.

This patch fixes this section mismatch:
WARNING: vmlinux.o(.text+0x1efc4): Section mismatch in reference from
the function apm821xx_pciex_init_port_hw() to the function
.init.text:ppc4xx_pciex_wait_on_sdr.isra.9()
The function apm821xx_pciex_init_port_hw() references the function
__init ppc4xx_pciex_wait_on_sdr.isra.9(). This is often because
apm821xx_pciex_init_port_hw lacks a __init annotation or the
annotation of ppc4xx_pciex_wait_on_sdr.isra.9 is wrong.
apm821xx_pciex_init_port_hw is only referenced by a struct in
__initdata, so it should be safe to add __init to
apm821xx_pciex_init_port_hw.

"Here are a few more powerpc things for you.
So you'll find here the conversion of the two new firmware sysfs
interfaces to the new API for self-removing files that Greg and Tejun
introduced, so they can finally remove the old one.
I'm also reverting the hwmon driver for powernv. I shouldn't have
merged it, I got a bit carried away here. I hadn't realized it was
never CCed to the relevant maintainer(s) and list(s), and happens to
have some issues so I'm taking it out and it will come back via the
proper channels.
The rest is a bunch of LE fixes (argh, some of the new stuff was
broken on LE, I really need to start testing LE myself !) and various
random fixes here and there.
Finally one bit that's not strictly a fix, which is the HVC OPAL
change to "kick" the HVC thread when the firmware tells us there is
new incoming data. I don't feel like waiting for this one, it's
simple enough, and it makes a big difference in console responsiveness
which is good for my nerves"

This patch removes an artificial RapidIO bus root device and establishes
actual device hierarchy by providing reference to real parent devices.
It also introduces device class for RapidIO controller devices (on-chip
or an eternal bridge, known as "mport").
Existing implementation was sufficient for SoC-based platforms that have
a single RapidIO controller. With introduction of devices using
multiple RapidIO controllers and PCIe-to-RapidIO bridges the old scheme
is very limiting or does not work at all. The implemented changes allow
to properly reference platform's local RapidIO mport devices and provide
device details needed for upper layers.
This change to RapidIO device hierarchy does not break any known
existing kernel or user space interfaces.

Pull main powerpc updates from Ben Herrenschmidt:
"This time around, the powerpc merges are going to be a little bit more
complicated than usual.
This is the main pull request with most of the work for this merge
window. I will describe it a bit more further down.
There is some additional cpuidle driver work, however I haven't
included it in this tree as it depends on some work in tip/timer-core
which Thomas accidentally forgot to put in a topic branch. Since I
didn't want to carry all of that tip timer stuff in powerpc -next, I
setup a separate branch on top of Thomas tree with just that cpuidle
driver in it, and Stephen has been carrying that in next separately
for a while now. I'll send a separate pull request for it.
Additionally, two new pieces in this tree add users for a sysfs API
that Tejun and Greg have been deprecating in drivers-core-next.
Thankfully Greg reverted the patch that removes the old API so this
merge can happen cleanly, but once merged, I will send a patch
adjusting our new code to the new API so that Greg can send you the
removal patch.
Now as for the content of this branch, we have a lot of perf work for
power8 new counters including support for our new "nest" counters
(also called 24x7) under pHyp (not natively yet).
We have new functionality when running under the OPAL firmware
(non-virtualized or KVM host), such as access to the firmware error
logs and service processor dumps, system parameters and sensors, along
with a hwmon driver for the latter.
There's also a bunch of bug fixes accross the board, some LE fixes,
and a nice set of selftests for validating our various types of copy
loops.
On the Freescale side, we see mostly new chip/board revisions, some
clock updates, better support for machine checks and debug exceptions,

If we do nothing in suspend/resume, some platform PCIe ip-block
can't guarantee the link back to L0 state from sleep, then, when
we read the EP device will hang. Only we send pme turnoff message
in pci controller suspend, and send pme exit message in resume, the
link state will be normal.
When we send pme turnoff message in pci controller suspend, the
links will into l2/l3 ready, then, host cannot communicate with
ep device, but pci-driver will call back EP device to save them
state. So we need to change platform_driver->suspend/resume to
syscore->suspend/resume.
So the new suspend/resume implementation, send pme turnoff message
in suspend, and send pme exit message in resume. And add a PME handler,
to response PME & message interrupt.
Change platform_driver->suspend/resume to syscore->suspend/resume.
pci-driver will call back EP device, to save EP state in
pci_pm_suspend_noirq, so we need to keep the link, until
pci_pm_suspend_noirq finish.

Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.
v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
Fix updating property values in sysfs
v4: Fixed build error on Powerpc
Fixed handling of dynamic nodes on powerpc
v3: Fixed handling of duplicate attribute and child node names
v2: switch to using sysfs bin_attributes which solve the problem of
reporting incorrect property size.

I'm really grumpy about this one. The line:
#include "../../../kernel/irq/settings.h"
should have been an alarm sign for all people who added their SOB to
this trainwreck.
When I cleaned up the mess people made with interrupt descriptors a
few years ago, I warned that I'm going to hunt down new offenders and
treat them with stinking trouts. In this case I'll use frozen shark
for a better educational value.
The whole idiocy which was done there could have been avoided with two
lines of perfectly fine code. And do not complain about the lack of
correct examples in tree.
The solution is simple:
Remove the brainfart and use the proper functions, which should
have been used in the first place

Commit 446f6d06fab0b49c61887ecbe8286d6aaa796637 ("powerpc/mpic: Properly
set default triggers") breaks the mpc7447_hpc_defconfig as follows:
CC arch/powerpc/sysdev/mpic.o
arch/powerpc/sysdev/mpic.c: In function 'mpic_set_irq_type':
arch/powerpc/sysdev/mpic.c:886:9: error: case label does not reduce to an integer constant
arch/powerpc/sysdev/mpic.c:890:9: error: case label does not reduce to an integer constant
arch/powerpc/sysdev/mpic.c:894:9: error: case label does not reduce to an integer constant
arch/powerpc/sysdev/mpic.c:898:9: error: case label does not reduce to an integer constant
Looking at the cpp output (gcc 4.7.3), I see:
case mpic->hw_set[MPIC_IDX_VECPRI_SENSE_EDGE] |
mpic->hw_set[MPIC_IDX_VECPRI_POLARITY_POSITIVE]:
The pointer into an array appears because CONFIG_MPIC_WEIRD=y is set
for this platform, thus enabling the following:
-------------------
#ifdef CONFIG_MPIC_WEIRD
static u32 mpic_infos[][MPIC_IDX_END] = {
[0] = { /* Original OpenPIC compatible MPIC */
[...]
#define MPIC_INFO(name) mpic->hw_set[MPIC_IDX_##name]
#else /* CONFIG_MPIC_WEIRD */
#define MPIC_INFO(name) MPIC_##name
#endif /* CONFIG_MPIC_WEIRD */
-------------------
Here we convert the case section to if/else if, and also add
the equivalent of a default case to warn about unknown types.
Boot tested on sbc8548, build tested on all defconfigs.

- Reworked Machine Check handling on kernels running without a
hypervisor (or acting as a hypervisor). Provides hooks to handle
some errors in real mode such as TLB errors, handle SLB errors,
etc...
- Support for retrieving memory error information from the service
processor on IBM servers running without a hypervisor and routing
them to the memory poison infrastructure.
- _PAGE_NUMA support on server processors
- 32-bit BookE relocatable kernel support
- FSL e6500 hardware tablewalk support
- A bunch of new/revived board support
- FSL e6500 deeper idle states and altivec powerdown support

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.
The one instance where we add an include for init.h covers off
a case where that file was implicitly getting it from another
header which itself didn't need it.

We currently have a user visible CONFIG_POWERNV_MSI option, but it
doesn't actually disable MSI for powernv. The MSI code is always built,
what it does disable is the inclusion of the MSI bitmap code, which
leads to a build error.
eg, with PPC_POWERNV=y and POWERNV_MSI=n we get:
arch/powerpc/platforms/built-in.o: In function `.pnv_teardown_msi_irqs':
pci.c:(.text+0x3558): undefined reference to `.msi_bitmap_free_hwirqs'
We don't really need a POWERNV_MSI symbol, just have the MSI bitmap code
depend directly on PPC_POWERNV.

Pull devicetree updates from Rob Herring:
"DeviceTree updates for 3.13. This is a bit larger pull request than
usual for this cycle with lots of clean-up.
- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to

Commit b5b4bb3f6a11f9 (of: only include prom.h on sparc) removed implicit
includes of of_*.h headers by powerpc's prom.h. Some components were
missed in initial clean-up patch, so add the necessary includes to fix
powerpc builds.

The current debugfs interface to scom is essentially unused
and racy. It uses two different files "address" and "data"
to perform accesses which is at best impractical for anything
but manual use by a developer.
This replaces it with an "access" file which represent the entire
scom address space which can be lseek/read/writen too.
This file only supports accesses that are 8 bytes aligned and
multiple of 8 bytes in size. The offset is logically the SCOM
address multiplied by 8.
Since nothing in userspace exploits that file at the moment, the ABI
change is a no-brainer.
