Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
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..."

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.

This was caused by that 'sd->groups == NULL' after building groups, which was caused by the empty 'sd->span'. The cpu's domain contained nothing because the cpu was assigned to a wrong node, due to the following unfortunate sequence of events: 1. The hypervisor sent a topology update to the guest OS, to notify changes to the cpu-node mapping. However, the update was actually redundant - i.e., the "new" mapping was exactly the same as the old one. 2. Due to this, the 'updated_cpus' mask turned out to be empty after exiting the 'for-loop' in arch_update_cpu_topology(). 3. So we ended up calling stop-machine() with an empty cpumask list, which made stop-machine internally elect cpumask_first(cpu_online_mask), i.e., CPU0 as the cpu to run the payload (the update_cpu_topology() function). 4. This causes update_cpu_topology() to be run by CPU0. And since 'updates' is kzalloc()'ed inside arch_update_cpu_topology(), update_cpu_topology() finds update->cpu as well as update->new_nid to be 0. In other words, we end up assigning CPU0 (and eventually its siblings) to node 0, incorrectly. Along with the following wrong updating, it causes the sched-domain rebuild code to break and crash the system. Fix this by skipping the topology update in cases where we find that the topology has not actually changed in reality (ie., spurious updates).

powerpc/le: Avoid creatng R_PPC64_TOCSAVE relocations for modules.
When building modules with a native le toolchain the linker will generate R_PPC64_TOCSAVE relocations when it's safe to omit saving r2 on a plt call. This isn't helpful in the conext of a kernel module and the kernel will fail to load those modules with an error like: nf_conntrack: Unknown ADD relocation: 109 This patch tells the linker to avoid createing R_PPC64_TOCSAVE relocations allowing modules to load.

powerpc/book3s: Fix mc_recoverable_range buffer overrun issue.
Currently we wrongly allocate mc_recoverable_range buffer (to hold recoverable ranges) based on size of the property "mcheck-recoverable-ranges". This results in allocating less memory to hold available recoverable range entries from /proc/device-tree/ibm,opal/mcheck-recoverable-ranges. This patch fixes this issue by allocating mc_recoverable_range buffer based on number of entries of recoverable ranges instead of device property size. Without this change we end up allocating less memory and run into memory corruption issue.

rapidio: rework device hierarchy and introduce mport class of devices
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.

cpufreq: powernv: cpufreq driver for powernv platform
Backend driver to dynamically set voltage and frequency on IBM POWER non-virtualized platforms. Power management SPRs are used to set the required PState. This driver works in conjunction with cpufreq governors like 'ondemand' to provide a demand based frequency and voltage setting on IBM POWER non-virtualized platforms. PState table is obtained from OPAL v3 firmware through device tree. powernv_cpufreq back-end driver would parse the relevant device-tree nodes and initialise the cpufreq subsystem on powernv platform. The code was originally written by svaidy@linux.vnet.ibm.com. Over time it was modified to accomodate bug-fixes as well as updates to the the cpu-freq core. Relevant portions of the change logs corresponding to those modifications are noted below: * The policy->cpus needs to be populated in a hotplug-invariant manner instead of using cpu_sibling_mask() which varies with cpu-hotplug. This is because the cpufreq core code copies this content into policy->related_cpus mask which should not vary on cpu-hotplug. [Authored by srivatsa.bhat@linux.vnet.ibm.com] * Create a helper routine that can return the cpu-frequency for the corresponding pstate_id. Also, cache the values of the pstate_max, pstate_min and pstate_nominal and nr_pstates in a static structure so that they can be reused in the future to perform any validations. [Authored by ego@linux.vnet.ibm.com] * Create a driver attribute named cpuinfo_nominal_freq which creates a sysfs read-only file named cpuinfo_nominal_freq. Export the frequency corresponding to the nominal_pstate through this interface. Nominal frequency is the highest non-turbo frequency for the platform. This is generally used for setting governor policies from user space for optimal energy efficiency. [Authored by ego@linux.vnet.ibm.com] * Implement a powernv_cpufreq_get(unsigned int cpu) method which will return the current operating frequency. Export this via the sysfs interface cpuinfo_cur_freq by setting powernv_cpufreq_driver.get to powernv_cpufreq_get().

powerpc/ppc64: Gracefully handle early interrupts
If we take an interrupt such as a trap caused by a BUG_ON before the MMU has been setup, the interrupt handlers try to enable virutal mode and cause a recursive crash, making the original problem very hard to debug. This fixes it by adjusting the "kernel_msr" value in the PACA so that it only has MSR_IR and MSR_DR (translation for instruction and data) set after the MMU has been initialized for the processor. We may still not have a console yet but at least we don't get into a recursive fault (and early debug console or memory dump via JTAG of the kernel buffer *will* give us the proper error).

This moves tm_recheckpoint to a C function and moves the tm_restore_sprs into
that function. It then adds IRQ disabling over the trechkpt critical section.
It also sets the TEXASR FS in the signals code to ensure this is never set now
that we explictly write the TM sprs in tm_recheckpoint.

powerpc/le: Enable RTAS events support
The current kernel code assumes big endian and parses RTAS events all wrong. The most visible effect is that we cannot honor EPOW events, meaning, for example, we cannot shut down a guest properly from the hypervisor. This new patch is largely inspired by Nathan's work: we get rid of all the bit fields in the RTAS event structures (even the unused ones, for consistency). We also introduce endian safe accessors for the fields used by the kernel (trivial rtas_error_type() accessor added for consistency).

powerpc: Correct emulated mtfsf instruction
The emulated (CONFIG_MATH_EMULATION_FULL) PowerPC Floating Point instruction mtfsf does not correctly copy bits from its source register to the Floating Point Status and Register (FPSCR). The error is in the preparation of the mask used to select the bits to be copied from the source to the FPSCR. Execution of the mtfsf instruction does not produce the same results on a MPC8548 platform (emulated floating point) as on MPC7410 or 440EP platforms (hardware floating point). This error has been detected using a Freescale MPC8548 based platform and the patch below tested using that platform.

Most of the changes were largely clean ups, and some documentation.
But there were a few features that were added. Uprobes now work with event triggers and multi buffers. Uprobes have support under ftrace and perf. The big feature is that the function tracer can now be used within the multi buffer instances. That is, you can now trace some functions in one buffer, others in another buffer, all functions in a third buffer and so on. They are basically agnostic from each other. This only works for the function tracer and not for the function graph trace, although you can have the function graph tracer running in the top level buffer (or any tracer for that matter) and have different function tracing going on in the sub buffers. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJTOthtAAoJEKQekfcNnQGu5c8H/Ana/U+0tmksp1dbHkRHsKSH +Fsv4Jeu8gf1NaFKHEhkUTcFtnzE6qAPV2VCrcJwXbhAhhwZm+LjrnWdoy3215S3 cQW4LftLEonh2cM36Cos74TulMEYN6XmL6dQZV+CILKQkDrWU4qJjQ64okXEkqrd 9iG3p/mSXyvJcmnyg61ALnMOhZDLsXY3djBhWBPhiTPGS6BRb9zh4Pmw6Zv0n2rJ U93Gt/3AQrv1ybu73dUxqP0abp60oXOiWoF/R2jcbKqIM+K9RPJX79unCV3jq3u9 f+6jMlB9PgAMqQj6ihJdwxKDDuzwyrVdEPnsgvl4jarCBCtVVwhKedBaKN/KS8k= =HdXY -----END PGP SIGNATURE----- Merge tag 'trace-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "Most of the changes were largely clean ups, and some documentation.

ARM has some caching fixes and PPC has transactional memory support in guests. MIPS has some fixes, with more probably coming in 3.16 as QEMU will soon get support for MIPS KVM. For x86 there are optimizations for debug registers, which trigger on some Windows games, and other important fixes for Windows guests. We now expose to the guest Broadwell instruction set extensions and also Intel MPX. There's also a fix/workaround for OS X guests, nested virtualization features (preemption timer), and a couple kvmclock refinements.

Devicetree changes for v3.15
Updates to devicetree core code. This branch contains the following notable changes:
* Add reserved memory binding
* Make struct device_node a kobject and remove legacy /proc/device-tree
* ePAPR conformance fixes
* Update in-kernel DTC copy to version v1.4.0
* Preparation changes for dynamic device tree overlays
* minor bug fixes and documentation changes
The most significant change in this branch is the conversion of struct
device_node to be a kobject that is exposed via sysfs and removal of the
old /proc/device-tree code. This simplifies the device tree handling
code and tightens up the lifecycle on device tree nodes.

Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
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..."

ACPI and power management updates for 3.15-rc1
- Device PM QoS support for latency tolerance constraints on systems with
hardware interfaces allowing such constraints to be specified. That is
necessary to prevent hardware-driven power management from becoming
overly aggressive on some systems and to prevent power management
features leading to excessive latencies from being used in some cases.
- Consolidation of the handling of ACPI hotplug notifications for device
objects. This causes all device hotplug notifications to go through
the root notify handler (that was executed for all of them anyway
before) that propagates them to individual subsystems, if necessary,
by executing callbacks provided by those subsystems (those callbacks
are associated with struct acpi_device objects during device
enumeration). As a result, the code in question becomes both smaller
in size and more straightforward and all of those changes should not
affect users.
- ACPICA update, including fixes related to the handling of _PRT in cases
when it is broken and the addition of "Windows 2013" to the list of
supported "features" for _OSI (which is necessary to support systems
that work incorrectly or don't even boot without it). Changes from
Bob Moore and Lv Zheng.
- Consolidation of ACPI _OST handling from Jiang Liu.
- ACPI battery and AC fixes allowing unusual system configurations to
be handled by that code from Alexander Mezin.
- New device IDs for the ACPI LPSS driver from Chiau Ee Chew.
- ACPI fan and thermal optimizations related to system suspend and resume
from Aaron Lu.
- Cleanups related to ACPI video from Jean Delvare.
- Assorted ACPI fixes and cleanups from Al Stone, Hanjun Guo, Lan Tianyu,
Paul Bolle, Tomasz Nowicki.
- Intel RAPL (Running Average Power Limits) driver cleanups from Jacob Pan.
- intel_pstate fixes and cleanups from Dirk Brandewie.
- cpufreq fixes related to system suspend/resume handling from Viresh Kumar.
- cpufreq core fixes and cleanups from Viresh Kumar, Stratos Karafotis,
Saravana Kannan, Rashika Kheria, Joe Perches.
- cpufreq drivers updates from Viresh Kumar, Zhuoyu Zhang, Rob Herring.
- cpuidle fixes related to the menu governor from Tuukka Tikkanen.
- cpuidle fix related to coupled CPUs handling from Paul Burton.
- Asynchronous execution of all device suspend and resume callbacks,
except for ->prepare and ->complete, during system suspend and resume
from Chuansheng Liu.
- Delayed resuming of runtime-suspended devices during system suspend for
the PCI bus type and ACPI PM domain.
- New set of PM helper routines to allow device runtime PM callbacks to
be used during system suspend and resume more easily from Ulf Hansson.
- Assorted fixes and cleanups in the PM core from Geert Uytterhoeven,
Prabhakar Lad, Philipp Zabel, Rashika Kheria, Sebastian Capella.

Pull ACPI and power management updates from Rafael Wysocki:
"The majority of this material spent some time in linux-next, some of
it even several weeks. There are a few relatively fresh commits in
it, but they are mostly fixes and simple cleanups.
ACPI took the lead this time, both in terms of the number of commits
and the number of modified lines of code, cpufreq follows and there
are a few changes in the PM core and in cpuidle too.
A new feature that already got some LWN.net's attention is the device
PM QoS extension allowing latency tolerance requirements to be
propagated from leaf devices to their ancestors with hardware
interfaces for specifying latency tolerance. That should help systems
with hardware-driven power management to avoid going too far with it
in cases when there are latency tolerance constraints.
There also are some significant changes in the ACPI core related to
the way in which hotplug notifications are handled. They affect PCI
hotplug (ACPIPHP) and the ACPI dock station code too. The bottom line
is that all those notification now go through the root notify handler
and are propagated to the interested subsystems by means of callbacks
instead of having to install a notify handler for each device object
that we can potentially get hotplug notifications for.
In addition to that ACPICA will now advertise "Windows 2013"
compatibility for _OSI, because some systems out there don't work
correctly if that is not done (some of them don't even boot).
On the system suspend side of things, all of the device suspend and
resume callbacks, except for ->prepare() and ->complete(), are now
going to be executed asynchronously as that turns out to speed up
system suspend and resume on some platforms quite significantly and we
have a few more optimizations in that area.
Apart from that, there are some new device IDs and fixes and cleanups
all over. In particular, the system suspend and resume handling by
cpufreq should be improved and the cpuidle menu governor should be a
bit more robust now.
Specifics:
- Device PM QoS support for latency tolerance constraints on systems
with hardware interfaces allowing such constraints to be specified.
That is necessary to prevent hardware-driven power management from
becoming overly aggressive on some systems and to prevent power
management features leading to excessive latencies from being used
in some cases.

Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq code updates from Thomas Gleixner:
"The irq department proudly presents:
- Another tree wide sweep of irq infrastructure abuse. Clear winner
of the trainwreck engineering contest was:
#include "../../../kernel/irq/settings.h"
- Tree wide update of irq_set_affinity() callbacks which miss a cpu
online check when picking a single cpu out of the affinity mask.
- Tree wide consolidation of interrupt statistics.
- Updates to the threaded interrupt infrastructure to allow explicit
wakeup of the interrupt thread and a variant of synchronize_irq()
which synchronizes only the hard interrupt handler. Both are
needed to replace the homebrewn thread handling in the mmc/sdhci
code.
- New irq chip callbacks to allow proper support for GPIO based irqs.
The GPIO based interrupts need to request/release GPIO resources
from request/free_irq.
- A few new ARM interrupt chips. No revolutionary new hardware, just
differently wreckaged variations of the scheme.
- Small improvments, cleanups and updates all over the place"
I was hoping that that trainwreck engineering contest was a April Fools'
joke. But no.
