The new memblock_virt APIs are used to replaced old bootmem API.
We need to allocate page below 4G for swiotlb.
That should fix regression on Andrew's system that is using swiotlb.

Pull spi updates from Mark Brown:
"A respun version of the merges for the pull request previously sent
with a few additional fixes. The last two merges were fixed up by
hand since the branches have moved on and currently have the prior
merge in them.
Quite a busy release for the SPI subsystem, mostly in cleanups big and
small scattered through the stack rather than anything else:
- New driver for the Broadcom BC63xx HSSPI controller
- Fix duplicate device registration for ACPI
- Conversion of s3c64xx to DMAEngine (this pulls in platform and DMA
changes upon which the transiton depends)
- Some small optimisations to reduce the amount of time we hold locks
in the datapath, eliminate some redundant checks and the size of a
spi_transfer
- Lots of fixes, cleanups and general enhancements to drivers,
especially the rspi and Atmel drivers"

Pull thermal management updates from Zhang Rui:
"This time, the biggest change is the work of representing hardware
thermal properties in device tree infrastructure.
This work includes the introduction of a device tree bindings for
describing the hardware thermal behavior and limits, and also a parser
to read and interpret the data, and build thermal zones and thermal
binding parameters. It also contains three examples on how to use the
new representation on sensor devices, using three different drivers to
accomplish it. One driver is in thermal subsystem, the TI SoC
thermal, and the other two drivers are in hwmon subsystem.
Actually, this would be the first step of the complete work because we
still need to check other potential drivers to be converted and then
validate the proposed API. But the reason why I include it in this
pull request is that, first, this change does not hurt any others
without using this approach, second, the principle and concept of this
change would not break after converting the remaining drivers. BTW,
as you can see, there are several points in this change that do not
belong to thermal subsystem. Because it has been suggested by Guenter
R that in such cases, it is recommended to send the complete series
via one single subsystem.
Specifics:
- representing hardware thermal properties in device tree
infrastructure
- fix a regression that the imx thermal driver breaks system suspend.
- introduce ACPI INT3403 thermal driver to retrieve temperature data
from the INT3403 ACPI device object present on some systems.
- introduce debug statement for thermal core and step_wise governor.
- assorted fixes and cleanups for thermal core, cpu cooling, exynos
thrmal, intel powerclamp and imx thermal driver"

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
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.

Ramachandra.

"Updates of SoC-near drivers and other driver updates that makes more

Pull ARM SoC cleanups from Olof Johansson:
"This is the branch where we usually queue up cleanup efforts, moving
drivers out of the architecture directory, header file restructuring,
etc. Sometimes they tangle with new development so it's hard to keep
it strictly to cleanups.
Some of the things included in this branch are:
* Atmel SAMA5 conversion to common clock
* Reset framework conversion for tegra platforms
- Some of this depends on tegra clock driver reworks that are shared
with Mike Turquette's clk tree.
* Tegra DMA refactoring, which are shared branches with the DMA tree.
* Removal of some header files on exynos to prepare for
multiplatform"

Split omap3 core padconf area into two as some of the registers in
the padconf area are not accessible and used for other devices.
Also fix the interrupt number for omap2 RNG, and add basic support
for sbc-3xxx with cm-t3730.
Note that the minor merge conflicts for omap_hwmod_2xxx_ipblock_data.c
can be solved by just dropping the legacy hwmod data for interrupts
for v3.14.

Pull Xen updates from Konrad Rzeszutek Wilk:
"Two major features that Xen community is excited about:
The first is event channel scalability by David Vrabel - we switch
over from an two-level per-cpu bitmap of events (IRQs) - to an FIFO
queue with priorities. This lets us be able to handle more events,
have lower latency, and better scalability. Good stuff.
The other is PVH by Mukesh Rathor. In short, PV is a mode where the
kernel lets the hypervisor program page-tables, segments, etc. With
EPT/NPT capabilities in current processors, the overhead of doing this
in an HVM (Hardware Virtual Machine) container is much lower than the
hypervisor doing it for us.
In short we let a PV guest run without doing page-table, segment,
syscall, etc updates through the hypervisor - instead it is all done
within the guest container. It is a "hybrid" PV - hence the 'PVH'
name - a PV guest within an HVM container.
The major benefits are less code to deal with - for example we only
use one function from the the pv_mmu_ops (which has 39 function
calls); faster performance for syscall (no context switches into the
hypervisor); less traps on various operations; etc.
It is still being baked - the ABI is not yet set in stone. But it is
pretty awesome and we are excited about it.
Lastly, there are some changes to ARM code - you should get a simple
conflict which has been resolved in #linux-next.
In short, this pull has awesome features.
Features:
- FIFO event channels. Key advantages: support for over 100,000
events (2^17), 16 different event priorities, improved fairness in
event latency through the use of FIFOs.
- Xen PVH support. "It’s a fully PV kernel mode, running with
paravirtualized disk and network, paravirtualized interrupts and
timers, no emulated devices of any kind (and thus no qemu), no BIOS
or legacy boot — but instead of requiring PV MMU, it uses the HVM
hardware extensions to virtualize the pagetables, as well as system
calls and other privileged operations." (from "The
Paravirtualization Spectrum, Part 2: From poles to a spectrum")
Bug-fixes:
- Fixes in balloon driver (refactor and make it work under ARM)
- Allow xenfb to be used in HVM guests.
- Allow xen_platform_pci=0 to work properly.
- Refactors in event channels"

Switch to memblock interfaces for early memory allocator instead of
bootmem allocator. No functional change in beahvior than what it is in
current code from bootmem users points of view.
Archs already converted to NO_BOOTMEM now directly use memblock
interfaces instead of bootmem wrappers build on top of memblock. And
the archs which still uses bootmem, these new apis just fallback to
exiting bootmem APIs.

Introduce memblock memory allocation APIs which allow to support PAE or
LPAE extension on 32 bits archs where the physical memory start address
can be beyond 4GB. In such cases, existing bootmem APIs which operate
on 32 bit addresses won't work and needs memblock layer which operates
on 64 bit addresses.
So we add equivalent APIs so that we can replace usage of bootmem with
memblock interfaces. Architectures already converted to NO_BOOTMEM use
these new memblock interfaces. The architectures which are still not
converted to NO_BOOTMEM continue to function as is because we still
maintain the fal lback option of bootmem back-end supporting these new
interfaces. So no functional change as such.
In long run, once all the architectures moves to NO_BOOTMEM, we can get
rid of bootmem layer completely. This is one step to remove the core
code dependency with bootmem and also gives path for architectures to
move away from bootmem.
The proposed interface will became active if both CONFIG_HAVE_MEMBLOCK
and CONFIG_NO_BOOTMEM are specified by arch. In case
!CONFIG_NO_BOOTMEM, the memblock() wrappers will fallback to the
existing bootmem apis so that arch's not converted to NO_BOOTMEM
continue to work as is.
The meaning of MEMBLOCK_ALLOC_ACCESSIBLE and MEMBLOCK_ALLOC_ANYWHERE
is kept same.

Commit 4b59e6c47309 ("mm, show_mem: suppress page counts in
non-blockable contexts") introduced SHOW_MEM_FILTER_PAGE_COUNT to
suppress PFN walks on large memory machines. Commit c78e93630d15 ("mm:
do not walk all of system memory during show_mem") avoided a PFN walk in
the generic show_mem helper which removes the requirement for
SHOW_MEM_FILTER_PAGE_COUNT in that case.
This patch removes PFN walkers from the arch-specific implementations
that report on a per-node or per-zone granularity. ARM and unicore32
still do a PFN walk as they report memory usage on each bank which is a
much finer granularity where the debugging information may still be of
use. As the remaining arches doing PFN walks have relatively small
amounts of memory, this patch simply removes SHOW_MEM_FILTER_PAGE_COUNT.

Pull GPIO tree bulk changes from Linus Walleij:
"A big set this merge window, as we have much going on in this
subsystem. The changes to other subsystems (notably a slew of ARM
machines as I am doing away with their custom APIs) have all been
ACKed to the extent possible.
Major changes this time:
- Some core improvements and cleanups to the new GPIO descriptor API.
This seems to be working now so we can start the exodus to this
API, moving gradually away from the global GPIO numberspace.
- Incremental improvements to the ACPI GPIO core, and move the few
GPIO ACPI clients we have to the GPIO descriptor API right *now*
before we go any further. We actually managed to contain this
*before* we started to litter the kernel with yet another hackish
global numberspace for the ACPI GPIOs, which is a big win.
- The RFkill GPIO driver and all platforms using it have been
migrated to use the GPIO descriptors rather than fixed number
assignments. Tegra machine has been migrated as part of this.
- New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x. Those
should be really good examples of how I expect a nice GPIO driver
to look these days.
- Do away with custom GPIO implementations on a major part of the ARM
machines: ks8695, lpc32xx, mv78xx0. Make a first step towards the
same in the horribly convoluted Samsung S3C include forest. We
expect to continue to clean this up as we move forward.
- Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
lynxpoint.
This makes the GPIOlib core aware that a certain GPIO line is used
for IRQs and can then enforce some semantics such as disallowing a
GPIO line marked as in use for IRQ to be switched to output mode.
- Drop all use of irq_set_chip_and_handler_name(). The name provided
in these cases were just unhelpful tags like "mux" or "demux".
- Extend the MCP23s08 driver to handle interrupts.
- Minor incremental improvements for rcar, lynxpoint, em 74x164 and
msm drivers.
- Some non-urgent bug fixes here and there, duplicate #includes and
that usual kind of cleanups"

Although we allow recovery in this case, this is not supposed to be
the normal path for hotplugging a CPU back in. This path only exists
to serve those rare platforms where it's not possible to power down
the CPU or reset the CPU. This patch causes the kernel to print a
message when a platform uses this path.

Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:
* TPS658623: Use correct voltage table for SM2
* TPS658643: New voltage table for SM2
Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.
This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.
On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.

Pull scheduler changes from Ingo Molnar:
- Add the initial implementation of SCHED_DEADLINE support: a real-time
scheduling policy where tasks that meet their deadlines and
periodically execute their instances in less than their runtime quota
see real-time scheduling and won't miss any of their deadlines.
Tasks that go over their quota get delayed (Available to privileged
users for now)
- Clean up and fix preempt_enable_no_resched() abuse all around the
tree
- Do sched_clock() performance optimizations on x86 and elsewhere
- Fix and improve auto-NUMA balancing
- Fix and clean up the idle loop
- Apply various cleanups and fixes

Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Add Intel RAPL energy counter support (Stephane Eranian)
- Clean up uprobes (Oleg Nesterov)
- Optimize ring-buffer writes (Peter Zijlstra)
Tooling side changes, user visible:
- 'perf diff':
- Add column colouring improvements (Ramkumar Ramachandra)
- 'perf kvm':
- Add guest related improvements, including allowing to specify a
directory with guest specific /proc information (Dongsheng Yang)
- Add shell completion support (Ramkumar Ramachandra)
- Add '-v' option (Dongsheng Yang)
- Support --guestmount (Dongsheng Yang)
- 'perf probe':
- Support showing source code, asking for variables to be collected
at probe time and other 'perf probe' operations that use DWARF
information.
This supports only binaries with debugging information at this
time, detached debuginfo (aka debuginfo packages) support should
come in later patches (Masami Hiramatsu)
- 'perf record':
- Rename --no-delay option to --no-buffering, better reflecting its
purpose and freeing up '--delay' to take the place of
'--initial-delay', so that 'record' and 'stat' are consistent
(Arnaldo Carvalho de Melo)
- Default the -t/--thread option to no inheritance (Adrian Hunter)
- Make per-cpu mmaps the default (Adrian Hunter)
- 'perf report':
- Improve callchain processing performance (Frederic Weisbecker)
- Retain bfd reference to lookup source line numbers, greatly
optimizing, among other use cases, 'perf report -s srcline'
(Adrian Hunter)
- Improve callchain processing performance even more (Namhyung Kim)
- Add a perf.data file header window in the 'perf report' TUI,
associated with the 'i' hotkey, providing a counterpart to the
--header option in the stdio UI (Namhyung Kim)
- 'perf script':
- Add an option in 'perf script' to print the source line number
(Adrian Hunter)
- Add --header/--header-only options to 'script' and 'report', the
default is not tho show the header info, but as this has been the
default for some time, leave a single line explaining how to
obtain that information (Jiri Olsa)
- Add options to show comm, fork, exit and mmap PERF_RECORD_ events
(Namhyung Kim)
- Print callchains and symbols if they exist (David Ahern)
- 'perf timechart'
- Add backtrace support to CPU info
- Print pid along the name
- Add support for CPU topology
- Add new option --highlight'ing threads, be it by name or, if a
numeric value is provided, that run more than given duration
(Stanislav Fomichev)
- 'perf top':
- Make 'perf top -g' refer to callchains, for consistency with
other tools (David Ahern)
- 'perf trace':
- Handle old kernels where the "raw_syscalls" tracepoints were
called plain "syscalls" (David Ahern)
- Remove thread summary coloring, by Pekka Enberg.
- Honour -m option in 'trace', the tool was offering the option to
set the mmap size, but wasn't using it when doing the actual mmap
on the events file descriptors (Jiri Olsa)
- generic:
- Backport libtraceevent plugin support (trace-cmd repository, with
plugins for jbd2, hrtimer, kmem, kvm, mac80211, sched_switch,
function, xen, scsi, cfg80211 (Jiri Olsa)
- Print session information only if --stdio is given (Namhyung Kim)
Tooling side changes, developer visible (plumbing):
- Improve 'perf probe' exit path, release resources (Masami
Hiramatsu)
- Improve libtraceevent plugins exit path, allowing the registering
of an unregister handler to be called at exit time (Namhyung Kim)
- Add an alias to the build test makefile (make -C tools/perf
build-test) (Namhyung Kim)
- Get rid of die() and friends (good riddance!) in libtraceevent
(Namhyung Kim)
- Fix cross build problems related to pkgconfig and CROSS_COMPILE not
being propagated to the feature tests, leading to features being
tested in the host and then being enabled on the target (Mark
Rutland)
- Improve forked workload error reporting by sending the errno in the
signal data queueing integer field, using sigqueue and by doing the
signal setup in the evlist methods, removing open coded equivalents
in various tools (Arnaldo Carvalho de Melo)
- Do more auto exit cleanup chores in the 'evlist' destructor, so
that the tools don't have to all do that sequence (Arnaldo Carvalho
de Melo)
- Pack 'struct perf_session_env' and 'struct trace' (Arnaldo Carvalho
de Melo)
- Add test for building detached source tarballs (Arnaldo Carvalho de
Melo)
- Move some header files (tools/perf/ to tools/include/ to make them
available to other tools/ dwelling codebases (Namhyung Kim)
- Move logic to warn about kptr_restrict'ed kernels to separate
function in 'report' (Arnaldo Carvalho de Melo)
- Move hist browser selection code to separate function (Arnaldo
Carvalho de Melo)
- Move histogram entries collapsing to separate function (Arnaldo
Carvalho de Melo)
- Introduce evlist__for_each() & friends (Arnaldo Carvalho de Melo)
- Automate setup of FEATURE_CHECK_(C|LD)FLAGS-all variables (Jiri
Olsa)
- Move arch setup into seprate Makefile (Jiri Olsa)
- Make libtraceevent install target quieter (Jiri Olsa)
- Make tests/make output more compact (Jiri Olsa)
- Ignore generated files in feature-checks (Chunwei Chen)
- Introduce pevent_filter_strerror() in libtraceevent, similar in
purpose to libc's strerror() function (Namhyung Kim)
- Use perf_data_file methods to write output file in 'record' and
'inject' (Jiri Olsa)
- Use pr_*() functions where applicable in 'report' (Namhyumg Kim)
- Add 'machine' 'addr_location' struct to have full picture (machine,
thread, map, symbol, addr) for a (partially) resolved address,
reducing function signatures (Arnaldo Carvalho de Melo)
- Reduce code duplication in the histogram entry creation/insertion
(Arnaldo Carvalho de Melo)
- Auto allocate annotation histogram data structures (Arnaldo
Carvalho de Melo)
- No need to test against NULL before calling free, also set freed
memory in struct pointers to NULL, to help fixing use after free
bugs (Arnaldo Carvalho de Melo)
- Rename some struct DSO binary_type related members and methods, to
clarify its purpose and need for differentiation (symtab_type, ie
one is about the files .text, CFI, etc, i.e. its binary contents,
and the other is about where the symbol table came from (Arnaldo
Carvalho de Melo)
- Convert to new topic libraries, starting with an API one (sysfs,
debugfs, etc), renaming liblk in the process (Borislav Petkov)
- Get rid of some more panic() like error handling in libtraceevent.
(Namhyung Kim)
- Get rid of panic() like calls in libtraceevent (Namyung Kim)
- Start carving out symbol parsing routines (perf, just moving
routines to topic files in tools/lib/symbol/, tools that want to
use it need to integrate it directly, ie no
tools/lib/symbol/Makefile is provided (Arnaldo Carvalho de Melo)
- Assorted refactoring patches, moving code around and adding utility
evlist methods that will be used in the IPT patchset (Adrian
Hunter)
- Assorted mmap_pages handling fixes (Adrian Hunter)
- Several man pages typo fixes (Dongsheng Yang)
- Get rid of several die() calls in libtraceevent (Namhyung Kim)
- Use basename() in a more robust way, to avoid problems related to
different system library implementations for that function
(Stephane Eranian)
- Remove open coded management of short_name_allocated member (Adrian
Hunter)
- Several cleanups in the "dso" methods, constifying some parameters
and renaming some fields to clarify its purpose (Arnaldo Carvalho
de Melo)
- Add per-feature check flags, fixing libunwind related build
problems on some architectures (Jean Pihet)
- Do not disable source line lookup just because of one failure.
(Adrian Hunter)
- Several 'perf kvm' man page corrections (Dongsheng Yang)
- Correct the message in feature-libnuma checking, swowing the right
devel package names for various distros (Dongsheng Yang)
- Polish 'readn()' function and introduce its counterpart,
'writen()' (Jiri Olsa)
- Start moving timechart state from global variables to a 'perf_tool'
derived 'timechart' struct (Arnaldo Carvalho de Melo)

Pull strong stackprotector support from Ingo Molnar:
"This tree adds a CONFIG_CC_STACKPROTECTOR_STRONG=y, a new, stronger
stack canary checking method supported by the newest GCC versions (4.9
and later).
Here's the 'intensity comparison' between the various protection
modes:
- defconfig
11430641 kernel text size
36110 function bodies
- defconfig + CONFIG_CC_STACKPROTECTOR_REGULAR
11468490 kernel text size (+0.33%)
1015 of 36110 functions are stack-protected (2.81%)
- defconfig + CONFIG_CC_STACKPROTECTOR_STRONG via this patch
11692790 kernel text size (+2.24%)
7401 of 36110 functions are stack-protected (20.5%)
the strong model comes with non-trivial costs, which is why we
preserved the 'regular' and 'none' models as well"
