perf evlist: Do not use hard coded value for a mmap_pages default
So far what is in there by default is what we were using: 512KB + the control page, but the admin may change that, and if it does to a smaller value, all calls to tooling for non root users start failing, requiring that the user manually set --mmap_pages/-m. Use instead what is in /proc/sys/kernel/perf_event_mlock_kb.

perf trace: Let the perf_evlist__mmap autosize the number of pages to use

perf evlist: Improve the strerror_mmap method
Considering the per user locked pages limit, improve the message when a user uses multiple simultaneous perf mmap calls: When the request is more than the current maximum: [acme@ssdandy linux]$ trace -m 128 usleep 1 Error: Operation not permitted. Hint: Check /proc/sys/kernel/perf_event_mlock_kb (516 kB) setting. Hint: Tried using 516 kB. Hint: Try 'sudo sh -c "echo 1032 > /proc/sys/kernel/perf_event_mlock_kb"', or Hint: Try using a smaller -m/--mmap-pages value. [acme@ssdandy linux]$ And when the limit is less than that: [acme@ssdandy linux]$ trace -m 512 usleep 1 Error: Operation not permitted. Hint: Check /proc/sys/kernel/perf_event_mlock_kb (2056 kB) setting. Hint: Tried using 2052 kB. Hint: Try using a smaller -m/--mmap-pages value.

perf evlist: Fixup brown paper bag on "hint" for --mmap-pages cmdline arg
When failing due to asking for a number of mmap pages that is more than the max, it was suggesting that an even bigger number of mmap pages should be specified, doh, au contraire! Before: [acme@ssdandy linux]$ trace -m 128 usleep 1 Error: Operation not permitted. Hint: Check /proc/sys/kernel/perf_event_mlock_kb (516 kB) setting. Hint: Tried using 516 kB. Hint: Try using a bigger -m/--mmap-pages value. [acme@ssdandy linux]$ After: [acme@ssdandy linux]$ trace -m 128 usleep 1 Error: Operation not permitted. Hint: Check /proc/sys/kernel/perf_event_mlock_kb (516 kB) setting. Hint: Tried using 516 kB. Hint: Try using a smaller -m/--mmap-pages value. [acme@ssdandy linux]$ And to (really) clarify what happens above, when what the user requests is <= max and even then it fails, a changeset is being made to tell that this is a per user limit, not per process (in the above example there was another 'perf trace' running for this user, which was using all the pages it could use).

perf/x86/intel/uncore: Make sure only uncore events are collected
The uncore_collect_events functions assumes that event group might contain only uncore events which is wrong, because it might contain any type of events. This bug leads to uncore framework touching 'not' uncore events, which could end up all sorts of bugs. One was triggered by Vince's perf fuzzer, when the uncore code touched breakpoint event private event space as if it was uncore event and caused BUG: BUG: unable to handle kernel paging request at ffffffff82822068 IP: [<ffffffff81020338>] uncore_assign_events+0x188/0x250 ... The code in uncore_assign_events() function was looking for event->hw.idx data while the event was initialized as a breakpoint with different members in event->hw union. This patch forces uncore_collect_events() to collect only uncore events.

Pull perf events update from Ingo Molnar:
"On the kernel side there's few changes, the one that stands out is
PEBS machine state sampling support on x86, by Stephane Eranian.
On the tooling side:
User visible tooling changes:
- Don't open the DWARF info multiple times, keeping instead a dwfl
handle in struct dso, greatly speeding up 'perf report' on powerpc.
(Sukadev Bhattiprolu)
- Introduce PARSE_OPT_DISABLED option flag and use it to avoid
showing undersired options in tools that provides frontends to
'perf record', like sched, kvm, etc (Namhyung Kim)
- Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo
Carvalho de Melo)
- Fix annotation with kcore (Adrian Hunter)
- Support source line numbers in annotate using a hotkey (Andi Kleen)
- Callchain improvements including:
* Enable printing the srcline in the history
* Make get_srcline fall back to sym+offset (Andi Kleen)
- TUI hist_entry browser fixes, including showing missing overhead
value for first level callchain. Detected comparing the output of
--stdio/--gui (that matched) with --tui, that had this problem.
(Namhyung Kim)
- Support handling complete branch stacks as histograms (Andi Kleen)
Tooling infrastructure changes:
- Prep work for supporting per-pkg and snapshot counters in 'perf
stat' (Jiri Olsa)
- 'perf stat' refactorings, moving stuff from it to evsel.c to use in
per-pkg/snapshot format changes (Jiri Olsa)
- Add per-pkg format file parsing (Matt Fleming)
- Clean up libelf feature support code (Namhyung Kim)
- Add gzip decompression support for kernel modules (Namhyung Kim)
- More prep patches for Intel PT, including a a thread stack and more
stuff made available via the database export mechanism (Adrian
Hunter)
- More Intel PT work, including a facility to export sample data
(comms, threads, symbol names, etc) in a database friendly way,
with an script to use this to create a postgresql database.
(Adrian Hunter)
- Make sure that thread->mg->machine points to the machine where the
thread exists (it was being set only for the kmaps kernel modules
case, do it as well for the mmaps) and use it to shorten function
signatures (Arnaldo Carvalho de Melo)
... and lots of other fixes and smaller improvements"
* 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (91 commits)

asm-generic: asm/io.h rewrite
While there normally is no reason to have a pull request for asm-generic
but have all changes get merged through whichever tree needs them, I do
have a series for 3.19. There are two sets of patches that change
significant portions of asm/io.h, and this branch contains both in order
to resolve the conflicts:
- Will Deacon has done a set of patches to ensure that all architectures
define {read,write}{b,w,l,q}_relaxed() functions or get them by
including asm-generic/io.h. These functions are commonly used on ARM
specific drivers to avoid expensive L2 cache synchronization implied by
the normal {read,write}{b,w,l,q}, but we need to define them on all
architectures in order to share the drivers across architectures and
to enable CONFIG_COMPILE_TEST configurations for them
- Thierry Reding has done an unrelated set of patches that extends
the asm-generic/io.h file to the degree necessary to make it useful
on ARM64 and potentially other architectures.

ARM: SoC/OMAP GPMC driver cleanup and move for 3.19
The GPMC driver has traditionally been considered a part of the OMAP platform code and tightly interweaved with some of the boards. With this cleanup, it has finally come to the point where it makes sense to move it out of arch/arm into drivers/memory, where we already have other drivers for similar hardware. The cleanups are still ongoing, with the goal of eventually having a standalone driver that does not require an interface to architecture code. This is a separate branch because of dependencies on multiple other branches, and to keep the drivers changes separate from the normal cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIcj7mCrR//JCVInAQIEtBAAoxn09fc4oeyBy9HeAgcQSxglqlyiJzTG YeIYN3Hz9kCRh/KDG35OQDD0Zv6Yw3m4QLYym5x/W2atMl+7AwBOUKGAi6neEHzv DbhvmAr8/2I+3RnUQDAxcbqY/p3/sSatWsPgwrgXWmGJHQm5Ur/IfUcnOmqfA6w4 xag8EdwX43zxUCF7MFTdD5Vo4uzoYNtPaPHpEtFBn/UkGMolktUCXZPBD1DvgQEP Mdy9yKhpYy/6N/k8ZQUCfD177GW5mJMNDrQN3e+vdqJ05NBBfiORhJCxilo74FVQ NpX7I4AoYqgc+c0xJpQSZF2bAfAt53Ac8bPG6fNAf1GCw7O8ryjNybHWw9hK1mr3 aS4EEVsC3UJh/d6NAhbPWfB4reL9WqUgGapN8AiVsurt1Rj+eAp6mCY3qM37kPs4 feGBbCL0lfEPVKTWHskcdUjxxcSsj1xTPM/VDvitITjgINfv6EqUHDLPRT9V7ta1 VVbFwIgshScam2T5AolMd1CB8mkaTkkbZFnMqz93lFs43vltJFFqJOCnfPKsYgMz gf4sJ8/029sUJV2yjEHHMQNyurpGPqJ+BHa6bCLX82ERePFNJvBnm8Zm+kizNbD2 CGN38tysXOxKL6jIqT9D0bKO40w1dLJjamsl1SfesDBijZChhF77Lnpwx/EKtj+/ jYSRIijpCWk= =U4Fz -----END PGP SIGNATURE----- Merge tag 'omap-gpmc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann: "The GPMC driver has traditionally been considered a part of the OMAP platform code and tightly interweaved with some of the boards.

ARM: SoC DT updates for 3.19
The DT branch adds a lot of new stuff for additional SoC and board support. The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: * AMLogic Meson8 * ARM Realview in DT mode * Allwinner A80 * Broadcom BCM47081 * Broadcom Cygnus * Freescale LS1021A * Freescale Vybrid 500 series * Mediatek MT6592, MT8127, MT8135 * STMicroelectronics STiH410 * Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete. As usual, these get extended over time. There are also many new boards getting added, this is the list of model strings that are showing up in new dts files: * ARM RealView PB1176 * Altera SOCFPGA Arria 10 * Asus RT-N18U (BCM47081) * Buffalo WZR-1750DHP (BCM4708) * Buffalo WZR-600DHP2 (BCM47081) * Cygnus Enterprise Phone (BCM911360_ENTPHN) * D-Link DIR-665 * Google Spring * IGEP COM MODULE Rev.

ARM: SoC driver updates for 3.19
These are changes for drivers that are intimately tied to some SoC
and for some reason could not get merged through the respective
subsystem maintainer tree.
The largest single change here this time around is the Tegra
iommu/memory controller driver, which gets updated to the new
iommu DT binding. More drivers like this are likely to follow
for the following merge window, but we should be able to do
those through the iommu maintainer.
Other notable changes are:
* reset controller drivers from the reset maintainer (socfpga, sti, berlin)
* fixes for the keystone navigator driver merged last time
* at91 rtc driver changes related to the at91 cleanups
* ARM perf driver changes from Will Deacon
* updates for the brcmstb_gisb driver

for some reason could not get merged through the respective subsystem
maintainer tree.
The largest single change here this time around is the Tegra
iommu/memory controller driver, which gets updated to the new iommu DT
binding. More drivers like this are likely to follow for the
following merge window, but we should be able to do those through the
iommu maintainer.
Other notable changes are:
- reset controller drivers from the reset maintainer (socfpga, sti,
berlin)
- fixes for the keystone navigator driver merged last time
- at91 rtc driver changes related to the at91 cleanups
- ARM perf driver changes from Will Deacon
- updates for the brcmstb_gisb driver"

ARM: SoC cleanups for 3.19
The remaining cleanups for 3.19 are to a large part result of
devicetree conversion nearing completion on two other platforms
besides AT91:
* Like AT91, Renesas shmobile is in the process to migrate to DT and
multiplatform, but using a different approach of doing it one
SoC at a time. For 3.19, the r8a7791 platform and associated\
"Koelsch" board are considered complete and we remove the non-DT
non-multiplatform support for this.
* The ARM Versatile Express has supported DT and multiplatform
for a long time, but we have still kept the legacy board files
around, because not all drivers were fully working before. We
have finally taken the last step to remove the board files.
Other changes in this branch are preparation for the later branches
or just unrelated to the more interesting changes:
* The dts files for arm64 get moved into per-vendor directories for
a clearer structure.
* Some dead code removal (zynq, exynos, davinci, imx)
* Using pr_*() macros more consistently instead of printk(KERN_*)
in some platform code.

ARM: SoC cleanup on mach-at91 for 3.19
On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle. This is split out from the other cleanups purely based on the size of the branch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iD8DBQBUhyNX5t5GS2LDRf4RAnjxAKCER7eoLNadu1/93n/a9d1nUz4MoQCcCZUq BolxCOi0wr4YTcQtp7rHzWI= =ykAB -----END PGP SIGNATURE----- Merge tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer.

ARM: SoC non-critical bug fixes for 3.19
These are bug fixes for harmless problems that were not important
enough to get fixed in 3.19. This contains updates to the MAINTAINERS
file, in particular:
- Ben Dooks stepped down as Samsung co-maintainer (thanks Ben for
long years of maintaining this). Kukjin Kim, who has been
doing the work de-facto by himself recently is now the
only maintainer.
- Liviu, Sudeep and Lorenzo from ARM now officially maintain the
Versatile Express platform, which was orphaned (thanks for
- Gregory Fong and Florian Fainelli help out on the Broadcom BCM7XXX
platform
- Ray Jui and Scott Branden are the future maintainers for the
newly merged Broadcom Cygnus platform. Welcome!
In terms of actual fixes, we have the usual set of OMAP bug fixes,
which Tony Lindgren separates out well from the other OMAP changes,
one really ep93xx regression fix against 3.11 that didn't make it for
3.18, a few GIC changes from Marc Zyngier as a preparation for
later rework (the current code is wrong in a harmless way), on
Tegra regression and one samsung spelling fix.

- Significant DM thin-provisioning performance improvements to meet
performance requirements that were requested by the Gluster distributed filesystem. Specifically, dm-thinp now takes care to aggregate IO that will be issued to the same thinp block before issuing IO to the underlying devices. This really helps improve performance on HW RAID6 devices that have a writeback cache because it avoids RMW in the HW RAID controller. - Some stable fixes: fix leak in DM bufio if integrity profiles were enabled, use memzero_explicit in DM crypt to avoid any potential for information leak, and a DM cache fix to properly mark a cache block dirty if it was promoted to the cache via the overwrite optimization. - A few simple DM persistent data library fixes - DM cache multiqueue policy block promotion improvements. - DM cache discard improvements that take advantage of range (multiblock) discard support in the DM bio-prison. This allows for much more efficient bulk discard processing (e.g. when mkfs.xfs discards the entire device). - Some small optimizations in DM core and RCU deference cleanups - DM core changes to suspend/resume code to introduce the new internal suspend/resume interface that the DM thin-pool target now uses to suspend/resume active thin devices when the thin-pool must suspend/resume. This avoids forcing userspace to track all active thin volumes in a thin-pool when the thin-pool is suspended for the purposes of metadata or data space resize. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJUhcvVAAoJEMUj8QotnQNaB78H+wSA6sDJGOhc6e1KlWoFh4Hx hTmwm/O8Fxrp9StO3NPlcv9l+l9FX9pGzN/lo3OsxgWMTs/vLTKZ5SAe3/YT3/b9 6SFC7pC70+glakgMhhXWRvoeSEQC1OWb5BuvOF8irl2n+7B9NAn/zHd9pgpmyWHp nBXK2GJBMzVSiI47NMjo2n6007LgQq0xxSJ9luwdrpwjDqD1d406DrhzbHou5H2Y b8XJGQzUy0GZCX8ycwPVXo9svp2Bc+XajVcgOj5Qg7s2uV5car8NN7TxhSOKSXn2 VpiSyEa2MLHAbFuWtGs8XO98z/m5JlGf1eIgRO4s7w59URgpzdxOHXLlAoyqIGw= =opXi -----END PGP SIGNATURE----- Merge tag 'dm-3.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Significant DM thin-provisioning performance improvements to meet performance requirements that were requested by the Gluster distributed filesystem.

regulator: Updates for v3.19
The main thing this time around is support for suspend mode
configuration from DT which will enable some very useful power savings
on systems where we can't rely on the bootloader configuration. We
still don't really support dynamic configuration of this at runtime,
that may come later if there is any demand.
- Support for specifying the target regulation mode and voltage during
system suspend via DT, enabling power savings in that mode.
- Reduce the default verbosity of the logging on boot, improving boot
times especially for systems with very large numbers of regulators.
- Lots of cleanups and fixes for Maxim PMIC drivers.
- New driver for Richtek RT5033.
