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"

As demonstrated in the previous commit, the failure message from the msi
bitmap selftests is a bit subtle, it's easy to miss a failure in a busy
boot log.
So drop our check() macro and use WARN_ON() instead. This necessitates
inverting all the conditions as well.

When we added the alignment tests recently we failed to check they were
actually passing - oops.
They weren't passing, because the bitmap was full. We should also be a
bit more careful when checking the return code, a negative error return
could by divisible by our alignment value.

Currently msi_bitmap_alloc_hwirqs() will round up any IRQ allocation requests
to the nearest power of 2. eg. ask for 5 IRQs and you'll get 8. This wastes a
lot of IRQs which can be a scarce resource.
For cxl we may require multiple IRQs for every context that is attached to the
accelerator. There may be 1000s of contexts attached, hence we can easily run
out of IRQs, especially if we are needlessly wasting them.
This changes the msi_bitmap_alloc_hwirqs() to allocate only the required number
of IRQs, hence avoiding this wastage. It keeps the natural alignment
requirement though.

On PowerNV platforms, when a CPU is offline, we put it into nap mode.
It's possible that the CPU wakes up from nap mode while it is still
offline due to a stray IPI. A misdirected device interrupt could also
potentially cause it to wake up. In that circumstance, we need to clear
the interrupt so that the CPU can go back to nap mode.
In the past the clearing of the interrupt was accomplished by briefly
enabling interrupts and allowing the normal interrupt handling code
(do_IRQ() etc.) to handle the interrupt. This has the problem that
this code calls irq_enter() and irq_exit(), which call functions such
as account_system_vtime() which use RCU internally. Use of RCU is not
permitted on offline CPUs and will trigger errors if RCU checking is
enabled.
To avoid calling into any generic code which might use RCU, we adopt
a different method of clearing interrupts on offline CPUs. Since we
are on the PowerNV platform, we know that the system interrupt
controller is a XICS being driven directly (i.e. not via hcalls) by
the kernel. Hence this adds a new icp_native_flush_interrupt()
function to the native-mode XICS driver and arranges to call that
when an offline CPU is woken from nap. This new function reads the
interrupt from the XICS. If it is an IPI, it clears the IPI; if it
is a device interrupt, it prints a warning and disables the source.
Then it does the end-of-interrupt processing for the interrupt.
The other thing that briefly enabling interrupts did was to check and
clear the irq_happened flag in this CPU's PACA. Therefore, after
flushing the interrupt from the XICS, we also clear all bits except
the PACA_IRQ_HARD_DIS (interrupts are hard disabled) bit from the
irq_happened flag. The PACA_IRQ_HARD_DIS flag is set by power7_nap()
and is left set to indicate that interrupts are hard disabled. This
means we then have to ignore that flag in power7_nap(), which is
reasonable since it doesn't indicate that any interrupt event needs
servicing.

Allocate msis such that each time a new interrupt is requested,
the SRS (MSIR register select) to be used is allocated in a
round-robin fashion.
The end result is that the msi interrupts will be spread across
distinct MSIRs with the main benefit that now users can set
affinity to each msi int through the mpic irq backing up the
MSIR register.
This is achieved with the help of a newly introduced msi bitmap
api that allows specifying the starting point when searching
for a free msi interrupt.

Rename the irq controller associated with a MSI
interrupt to fsl-msi-<V>, where <V> is the virq
of the cascade irq backing up this MSI interrupt.
This way, one can set the affinity of a MSI
through the cascade irq associated with said MSI
interrupt.
Given this example /proc/interrupts snippet:
CPU0 CPU1 CPU2 CPU3
16: 0 0 0 0 OpenPIC 16 Edge mpic-error-int
17: 0 4 0 0 fsl-msi-224 0 Edge eth0-rx-0
18: 0 5 0 0 fsl-msi-225 1 Edge eth0-tx-0
19: 0 2 0 0 fsl-msi-226 2 Edge eth0
[...]
224: 0 11 0 0 OpenPIC 224 Edge fsl-msi-cascade
225: 0 0 0 0 OpenPIC 225 Edge fsl-msi-cascade
226: 0 0 0 0 OpenPIC 226 Edge fsl-msi-cascade
[...]
To change the affinity of MSI interrupt 17
(having the irq controller named "fsl-msi-224")
instead of writing /proc/irq/17/smp_affinity, use
the associated MSI cascade irq, in this case,
interrupt 224, e.g.:
echo 6 > /proc/irq/224/smp_affinity
Note that a MSI cascade irq covers several MSI
interrupts, so changing the affinity on the
cascade will impact all of the associated MSI
interrupts.

As we do for other fsl-mpic related cascaded irqchips
(e.g. error ints, mpic timers), use a normal irq handler
for msi irqs too.
This brings some advantages such as mask/unmask/ack/eoi
and irq state taken care behind the scenes, kstats
updates a.s.o plus access to features provided by mpic,
such as affinity.

The following commit prevents the MPC8548E on the XPedite5200 PrPMC
module from enumerating its PCI/PCI-X bus:
powerpc/fsl-pci: use 'Header Type' to identify PCIE mode
The previous patch prevents any Freescale PCI-X bridge from enumerating
the bus, if it is hardware strapped into Agent mode.
In PCI-X, the Host is responsible for driving the PCI-X initialization
pattern to devices on the bus, so that they know whether to operate in
conventional PCI or PCI-X mode as well as what the bus timing will be.
For a PCI-X PrPMC, the pattern is driven by the mezzanine carrier it is
installed onto. Therefore, PrPMCs are PCI-X Agents, but one per system
may still enumerate the bus.
This patch causes the device node of any PCI/PCI-X bridge strapped into
Agent mode to be checked for the fsl,pci-agent-force-enum property. If
the property is present in the node, the bridge will be allowed to
enumerate the bus.

The new MSI block in MPIC 4.3 added the MSIIR1 register,
with a different layout, in order to support 16 MSIR
registers. The msi binding was also updated so that
the "reg" reflects the newly introduced MSIIR1 register.
Virtual machines advertise these msi nodes by using the
compatible "fsl,vmpic-msi-v4.3" so add support for it.

In commit ae91d60ba88ef0bdb1b5e9b2363bd52fc45d2af7, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.
This is not tested and clearly changes the semantics, so it is only
something to consider.
The Coccinelle semantic patch that makes this change is as follows:
// <smpl>

(
!E1 & !E2

- !E1 & E2

mpic_msgrs has type struct mpic_msgr **, not struct mpic_msgr *, so the
elements of the array should have pointer type, not structure type.
The advantage of kcalloc is, that will prevent integer overflows which
could result from the multiplication of number of elements and size and
it is also a bit nicer to read.
The Coccinelle semantic patch that makes the first change is as follows:
// <smpl>

x =

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.

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 ..."

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

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.

Liu Gang, are you sure all of these error conditions are fatal? Why
does the rio driver fail if rmu is not present (e.g. on t4240)?

The PPC476GTR SoC supports message signalled interrupts (MSI) by writing
to special addresses within the High Speed Transfer Assist (HSTA) module.
This patch adds support for PCI MSI with a new system device. The DMA
window is also updated to allow access to the entire 42-bit address range
to allow PCI devices write access to the HSTA module.

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,
etc..."

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()

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

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: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.
