Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull core irq updates from Thomas Gleixner:
"The irq department delivers:
- Another tree wide update to get rid of the horrible create_irq
interface along with its even more horrible variants. That also
gets rid of the last leftovers of the initial sparse irq hackery.
arch/driver specific changes have been either acked or ignored.
- A fix for the spurious interrupt detection logic with threaded
interrupts.
- A new ARM SoC interrupt controller
- The usual pile of fixes and improvements all over the place"

[IA64] Change default PSR.ac from '1' to '0' (Fix erratum #237)
April 2014 Itanium processor specification update:
http://www.intel.com/content/www/us/en/processors/itanium/itanium-specification-update.html
describes this erratum:
=========================================================================
237. Under a complex set of conditions, store to load forwarding for a
sub 8-byte load may complete incorrectly
Problem: A load instruction may complete incorrectly when a code sequence
using 4-byte or smaller load and store operations to the same address
is executed in combination with specific timing of all the following
concurrent conditions: store to load forwarding, alignment checking
enabled, a mis-predicted branch, and complex cache utilization activity.
Implication: The affected sub 8-byte instruction may complete
incorrectly resulting in unpredictable system behavior. There is an
extremely low probability of exposure due to the significant number of
complex microarchitectural concurrent conditions required to encounter
the erratum.
Workaround: Set PSR.ac = 0 to completely avoid the erratum. Disabling
Hyper-Threading will significantly reduce exposure to the conditions
that contribute to encountering the erratum.
Status: See the Summary Table of Changes for the affected steppings.
=========================================================================
[Table of changes essentially lists all models from McKinley to Tukwila]
The PSR.ac bit controls whether the processor will always generate
an unaligned reference trap (0x5a00) for a misaligned data access
(when PSR.ac=1) or if it will let the access succeed when running
on a cpu that implements logic to handle some unaligned accesses.

CPU hotplug notifiers registration fixes for 3.15-rc1
The purpose of this single series of commits from Srivatsa S Bhat (with a small piece from Gautham R Shenoy) touching multiple subsystems that use CPU hotplug notifiers is to provide a way to register them that will not lead to deadlocks with CPU online/offline operations as described in the changelog of commit |

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.

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.
- 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

"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"

mm: fix GFP_THISNODE callers and clarify
GFP_THISNODE is for callers that implement their own clever fallback to remote nodes. It restricts the allocation to the specified node and does not invoke reclaim, assuming that the caller will take care of it when the fallback fails, e.g. through a subsequent allocation request without GFP_THISNODE set. However, many current GFP_THISNODE users only want the node exclusive aspect of the flag, without actually implementing their own fallback or triggering reclaim if necessary. This results in things like page migration failing prematurely even when there is easily reclaimable memory available, unless kswapd happens to be running already or a concurrent allocation attempt triggers the necessary reclaim. Convert all callsites that don't implement their own fallback strategy to __GFP_THISNODE. This restricts the allocation a single node too, but at the same time allows the allocator to enter the slowpath, wake kswapd, and invoke direct reclaim if necessary, to make the allocation happen when memory is full.

No architecture uses the "data" parameter in ftrace_dyn_arch_init() in any way, it just sets the value to 0. And this is used as a return value in the caller -- ftrace_init, which just checks the retval against zero. Note there is also "return 0" in every ftrace_dyn_arch_init.

ia64/efi: Implement efi_enabled()
There's no good reason to keep efi_enabled() under CONFIG_X86 anymore, since nothing about the implementation is specific to x86. Set EFI feature flags in the ia64 boot path instead of claiming to support all features. The old behaviour was actually buggy since efi.memmap never points to a valid memory map, so we shouldn't be claiming to support EFI_MEMMAP. Fortunately, this bug was never triggered because EFI_MEMMAP isn't used outside of arch/x86 currently, but that may not always be the case.

ACPI and power management updates for 3.14-rc1
- ACPI core changes to make it create a struct acpi_device object for every
device represented in the ACPI tables during all namespace scans regardless
of the current status of that device. In accordance with this, ACPI hotplug
operations will not delete those objects, unless the underlying ACPI tables
go away.
- On top of the above, new sysfs attribute for ACPI device objects allowing
user space to check device status by triggering the execution of _STA for
its ACPI object. From Srinivas Pandruvada.
- ACPI core hotplug changes reducing code duplication, integrating the
PCI root hotplug with the core and reworking container hotplug.
- ACPI core simplifications making it use ACPI_COMPANION() in the code
"glueing" ACPI device objects to "physical" devices.
- ACPICA update to upstream version 20131218. This adds support for the
DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug
facilities. From Bob Moore, Lv Zheng and Betty Dall.
- Init code change to carry out the early ACPI initialization earlier.
That should allow us to use ACPI during the timekeeping initialization
and possibly to simplify the EFI initialization too. From Chun-Yi Lee.
- Clenups of the inclusions of ACPI headers in many places all over from
Lv Zheng and Rashika Kheria (work in progress).
- New helper for ACPI _DSM execution and rework of the code in drivers
that uses _DSM to execute it via the new helper. From Jiang Liu.
- New Win8 OSI blacklist entries from Takashi Iwai.
- Assorted ACPI fixes and cleanups from Al Stone, Emil Goode, Hanjun Guo,
Lan Tianyu, Masanari Iida, Oliver Neukum, Prarit Bhargava, Rashika Kheria,
Tang Chen, Zhang Rui.
- intel_pstate driver updates, including proper Baytrail support, from

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.
- On top of the above, new sysfs attribute for ACPI device objects
allowing user space to check device status by triggering the

ACPICA: Cleanup the option of forcing the use of the RSDT.
This change adds a runtime option that will force ACPICA to use the RSDT instead of the XSDT. Although the ACPI spec requires that an XSDT be used instead of the RSDT, the XSDT has been found to be corrupt or ill-formed on some machines. This option is already in the Linux kernel. When it is back ported to ACPICA, code is re-written to follow ACPICA coding style. This patch is the generation of the integration.

efi: x86: ia64: provide a generic efi_config_init()
Common to (U)EFI support on all platforms is the global "efi" data structure, and the code that parses the System Table to locate addresses to populate that structure with. This patch adds both of these to the global EFI driver code and removes the local definition of the global "efi" data structure from the x86 and ia64 code. Squashed into one big patch to avoid breaking bisection.
