- Most extensive changes this cycle are the DM core improvements to add
full blk-mq support to request-based DM.
- disabled by default but user can opt-in with CONFIG_DM_MQ_DEFAULT
- depends on some blk-mq changes from Jens' for-4.1/core branch so
that explains why this pull is built on linux-block.git
- Update DM to use name_to_dev_t() rather than open-coding a less
capable device parser.
- includes a couple small improvements to name_to_dev_t() that offer
stricter constraints that DM's code provided.
- Improvements to the dm-cache "mq" cache replacement policy.
- A DM crypt crypt_ctr() error path fix and an async crypto deadlock fix.
- A small efficiency improvement for DM crypt decryption by leveraging
immutable biovecs.
- Add error handling modes for corrupted blocks to DM verity.
- A new "log-writes" DM target from Josef Bacik that is meant for
file system developers to test file system integrity at particular
points in the life of a file system.
- A few DM log userspace cleanups and fixes.
- A few Documentation fixes (for thin, cache, crypt and switch).

proc: show locks in /proc/pid/fdinfo/X
Let's show locks which are associated with a file descriptor in its fdinfo file. Currently we don't have a reliable way to determine who holds a lock. We can find some information in /proc/locks, but PID which is reported there can be wrong. For example, a process takes a lock, then forks a child and dies. In this case /proc/locks contains the parent pid, which can be reused by another process. $ cat /proc/locks ... 6: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF ... $ ps -C rpcbind PID TTY TIME CMD 332 ? 00:00:00 rpcbind $ cat /proc/332/fdinfo/4 pos: 0 flags: 0100000 mnt_id: 22 lock: 1: FLOCK ADVISORY WRITE 324 00:13:13431 0 EOF $ ls -l /proc/332/fd/4 lr-x------ 1 root root 64 Mar 5 14:43 /proc/332/fd/4 -> /run/rpcbind.lock $ ls -l /proc/324/fd/ total 0 lrwx------ 1 root root 64 Feb 27 14:50 0 -> /dev/pts/0 lrwx------ 1 root root 64 Feb 27 14:50 1 -> /dev/pts/0 lrwx------ 1 root root 64 Feb 27 14:49 2 -> /dev/pts/0 You can see that the process with the 324 pid doesn't hold the lock. This information is required for proper dumping and restoring file locks.

rtc: stmp3xxx: use optional crystal in low power states
The rtc's status register allows to determine if a 32k crystal is connected to keep the rtc running in low power states provided the corresponding fuse bits were blown correctly during production. (In case they were not, the right frequency can be stated in the device tree.) If there is no such crystal available force the 24 MHz XTAL clock to keep running to retain the right date and time. Otherwise use the crystal to save some power. It would be nice to only switch to the crystal when the XTAL clock is about to be disabled and keep the crystal off when unneeded because XTAL is always on while the chip is powered on. But as sudden power loss isn't detectable this is not save.

Doc: dt: arch_timer: discourage clock-frequency use
The ARM Generic Timer (AKA the architected timer, arm_arch_timer) features a CPU register (CNTFRQ) which firmware is intended to initialize, and non-secure software can read to determine the frequency of the timer. On CPUs with secure state, this register cannot be written from non-secure states. The firmware of early SoCs featuring the timer did not correctly initialize CNTFRQ correctly on all CPUs, requiring the frequency to be described in DT as a workaround. This workaround is not complete however as it is exposed to all software in a privileged non-secure mode (including guests running under a hypervisor). The firmware and DTs for recent SoCs have followed the example set by these early SoCs. This patch updates the arch timer binding documentation to make it clearer that the use of the clock-frequency property is a poor work-around. The MMIO generic timer binding is similarly updated, though this is less of a concern as there is generally no need to expose the MMIO timers to guest OSs.

zram: deprecate zram attrs sysfs nodes
Add Documentation/ABI/obsolete/sysfs-block-zram file and list obsolete and deprecated attributes there. The patch also adds additional information to zram documentation and describes the basic strategy: - the existing RW nodes will be downgraded to WO nodes (in 4.11) - deprecated RO sysfs nodes will eventually be removed (in 4.11) Users will be additionally notified about deprecated attr usage by pr_warn_once() (added to every deprecated attr _show()), as suggested by Minchan Kim. User space is advised to use zram<id>/stat, zram<id>/io_stat and zram<id>/mm_stat files.

zram: describe device attrs in documentation
Briefly describe exported device stat attrs in zram documentation. We will eventually get rid of per-stat sysfs nodes and, thus, clean up Documentation/ABI/testing/sysfs-block-zram file, which is the only source of information about device sysfs nodes. Add `num_migrated' description, since there is no independent `num_migrated' sysfs node (and no corresponding sysfs-block-zram entry), it will be exported via zram<id>/mm_stat file. At this point we can provide minimal description, because sysfs-block-zram still contains detailed information.

zram: remove `num_migrated' device attr
This patch introduces rework to zram stats. We have per-stat sysfs nodes,
and it makes things a bit hard to use in user space: it doesn't give an
immediate stats 'snapshot', it requires user space to use more syscalls -
open, read, close for every stat file, with appropriate error checks on
every step, etc.
First, zram now accounts block layer statistics, available in
/sys/block/zram<id>/stat and /proc/diskstats files. So some new stats are
available (see Documentation/block/stat.txt), besides, zram's activities
now can be monitored by sysstat's iostat or similar tools.
Example:
cat /sys/block/zram0/stat
248 0 1984 0 251029 0 2008232 5120 0 5116 5116
Second, group currently exported on per-stat basis nodes into two
categories (files):
-- zram<id>/io_stat
accumulates device's IO stats, that are not accounted by block layer,
and contains:
failed_reads
failed_writes
invalid_io
notify_free
Example:
cat /sys/block/zram0/io_stat
0 0 0 652572
-- zram<id>/mm_stat
accumulates zram mm stats and contains:
orig_data_size
compr_data_size
mem_used_total
mem_limit
mem_used_max
zero_pages
num_migrated
Example:
cat /sys/block/zram0/mm_stat
434634752 270288572 279158784 0 579895296 15060 0
per-stat sysfs nodes are now considered to be deprecated and we plan to
remove them (and clean up some of the existing stat code) in two years (as
of now, there is no warning printed to syslog about deprecated stats being
used). User space is advised to use the above mentioned 3 files.
This patch (of 7):
Remove sysfs `num_migrated' attribute. We are moving away from per-stat
device attrs towards 3 stat files that will accumulate io and mm stats in
a format similar to block layer statistics in /sys/block/<dev>/stat. That
will be easier to use in user space, and reduce the number of syscalls
needed to read zram device statistics.
`num_migrated' will return back in zram<id>/mm_stat file.

mm: new pfn_mkwrite same as page_mkwrite for VM_PFNMAP
This will allow FS that uses VM_PFNMAP | VM_MIXEDMAP (no page structs) to
get notified when access is a write to a read-only PFN.
This can happen if we mmap() a file then first mmap-read from it to
page-in a read-only PFN, than we mmap-write to the same page.
We need this functionality to fix a DAX bug, where in the scenario above
we fail to set ctime/mtime though we modified the file. An xfstest is
attached to this patchset that shows the failure and the fix. (A DAX
patch will follow)
This functionality is extra important for us, because upon dirtying of a
pmem page we also want to RDMA the page to a remote cluster node.
We define a new pfn_mkwrite and do not reuse page_mkwrite because
1 - The name ;-)
2 - But mainly because it would take a very long and tedious
audit of all page_mkwrite functions of VM_MIXEDMAP/VM_PFNMAP
users. To make sure they do not now CRASH. For example current
DAX code (which this is for) would crash.
If we would want to reuse page_mkwrite, We will need to first
patch all users, so to not-crash-on-no-page. Then enable this
patch. But even if I did that I would not sleep so well at night.
Adding a new vector is the safest thing to do, and is not that
expensive. an extra pointer at a static function vector per driver.
Also the new vector is better for performance, because else we
Will call all current Kernel vectors, so to:
check-ha-no-page-do-nothing and return.
No need to call it from do_shared_fault because do_wp_page is called to
change pte permissions anyway.

Currently, pages which are marked as unevictable are protected from compaction, but not from other types of migration. The POSIX real time extension explicitly states that mlock() will prevent a major page fault, but the spirit of this is that mlock() should give a process the ability to control sources of latency, including minor page faults. However, the mlock manpage only explicitly says that a locked page will not be written to swap and this can cause some confusion. The compaction code today does not give a developer who wants to avoid swap but wants to have large contiguous areas available any method to achieve this state. This patch introduces a sysctl for controlling compaction behavior with respect to the unevictable lru. Users who demand no page faults after a page is present can set compact_unevictable_allowed to 0 and users who need the large contiguous areas can enable compaction on locked memory by leaving the default value of 1. To illustrate this problem I wrote a quick test program that mmaps a large number of 1MB files filled with random data. These maps are created locked and read only. Then every other mmap is unmapped and I attempt to allocate huge pages to the static huge page pool. When the compact_unevictable_allowed sysctl is 0, I cannot allocate hugepages after fragmenting memory. When the value is set to 1, allocations succeed.

sound updates for 4.1-rc1
There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level
to the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC
Misc:
- ice1724: Improved ESI W192M support
- emu10k1: Emu 1010 fixes/enhancement

dm verity: add error handling modes for corrupted blocks
Add device specific modes to dm-verity to specify how corrupted
blocks should be handled. The following modes are defined:
- DM_VERITY_MODE_EIO is the default behavior, where reading a
corrupted block results in -EIO.
- DM_VERITY_MODE_LOGGING only logs corrupted blocks, but does
not block the read.
- DM_VERITY_MODE_RESTART calls kernel_restart when a corrupted
block is discovered.
In addition, each mode sends a uevent to notify userspace of
corruption and to allow further recovery actions.
The driver defaults to previous behavior (DM_VERITY_MODE_EIO)
and other modes can be enabled with an additional parameter to
the verity table.

dm: impose configurable deadline for dm_request_fn's merge heuristic
Otherwise, for sequential workloads, the dm_request_fn can allow excessive request merging at the expense of increased service time. Add a per-device sysfs attribute to allow the user to control how long a request, that is a reasonable merge candidate, can be queued on the request queue. The resolution of this request dispatch deadline is in microseconds (ranging from 1 to 100000 usecs), to set a 20us deadline: echo 20 > /sys/block/dm-7/dm/rq_based_seq_io_merge_deadline The dm_request_fn's merge heuristic and associated extra accounting is disabled by default (rq_based_seq_io_merge_deadline is 0). This sysfs attribute is not applicable to bio-based DM devices so it will only ever report 0 for them. By allowing a request to remain on the queue it will block others requests on the queue. But introducing a short dequeue delay has proven very effective at enabling certain sequential IO workloads on really fast, yet IOPS constrained, devices to build up slightly larger IOs -- yielding 90+% throughput improvements. Having precise control over the time taken to wait for larger requests to build affords control beyond that of waiting for certain IO sizes to accumulate (which would require a deadline anyway). This knob will only ever make sense with sequential IO workloads and the particular value used is storage configuration specific. Given the expected niche use-case for when this knob is useful it has been deemed acceptable to expose this relatively crude method for crafting optimal IO on specific storage -- especially given the solution is simple yet effective. In the context of DM multipath, it is advisable to tune this sysfs attribute to a value that offers the best performance for the common case (e.g. if 4 paths are expected active, tune for that; if paths fail then performance may be slightly reduced). Alternatives were explored to have request-based DM autotune this value (e.g. if/when paths fail) but they were quickly deemed too fragile and complex to warrant further design and development time. If this problem proves more common as faster storage emerges we'll have to look at elevating a generic solution into the block core.

Pull ARM updates from Russell King:
"Included in this update are both some long term fixes and some new
features.
Fixes:
- An integer overflow in the calculation of ELF_ET_DYN_BASE.
- Avoiding OOMs for high-order IOMMU allocations
- SMP requires the data cache to be enabled for synchronisation
primitives to work, so prevent the CPU_DCACHE_DISABLE option being
visible on SMP builds.
- A bug going back 10+ years in the noMMU ARM94* CPU support code,
where it corrupts registers. Found by folk getting Linux running
on their cameras.
- Versatile Express needs an errata workaround enabled for CPU
hot-unplug to work.
Features:
- Clean up module linker by handling out of range relocations
separately from relocation cases we don't handle.
- Fix a long term bug in the pci_mmap_page_range() code, which we
hope won't impact userspace (we hope there's no users of the
existing broken interface.)
- Don't map DMA coherent allocations when we don't have a MMU.
- Drop experimental status for SMP_ON_UP.
- Warn when DT doesn't specify ePAPR mandatory cache properties.
- Add documentation concerning how we find the start of physical
memory for AUTO_ZRELADDR kernels, detailing why we have chosen the
mask and the implications of changing it.
- Updates from Ard Biesheuvel to address some issues with large
kernels (such as allyesconfig) failing to link.
- Allow hibernation to work on modern (ARMv7) CPUs - this appears to
have never worked in the past on these CPUs.
- Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output
format (hopefully without userspace breaking... let's hope that if
it causes someone a problem, they tell us.)
- Fix tegra-ahb DT offsets.
- Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/
flush_dcache_all()) code to be more efficient, and enable this
errata workaround by default for ARMv7+SMP CPUs. This complements
the Versatile Express fix above.
- Rework ARMv7 context code for errata 430973, so that only Cortex A8
CPUs are impacted by the branch target buffer flush when this
errata is enabled. Also update the help text to indicate that all
r1p* A8 CPUs are impacted.
- Switch ARM to the generic show_mem() implementation, it conveys all
the information which we were already reporting.
- Prevent slow timer sources being used for udelay() - timers running
at less than 1MHz are not useful for this, and can cause udelay()
to return immediately, without any wait. Using such a slow timer
is silly.
- VDSO support for 32-bit ARM, mainly for gettimeofday() using the
ARM architected timer.
- Perf support for Scorpion performance monitoring units"

Pull power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes and cleanups all over, although there are a few
items that sort of fall into the new feature category.
First off, we have new callbacks for PM domains that should help us to
handle some issues related to device initialization in a better way.
There also is some consolidation in the unified device properties API
area allowing us to use that inferface for accessing data coming from
platform initialization code in addition to firmware-provided data.
We have some new device/CPU IDs in a few drivers, support for new
chips and a new cpufreq driver too.

Wysocki, Kevin Hilman)

lib/ioremap.c: add huge I/O map capability interfaces
Add ioremap_pud_enabled() and ioremap_pmd_enabled(), which return 1 when I/O mappings with pud/pmd are enabled on the kernel. ioremap_huge_init() calls arch_ioremap_pud_supported() and arch_ioremap_pmd_supported() to initialize the capabilities at boot-time. A new kernel option "nohugeiomap" is also added, so that user can disable the huge I/O map capabilities when necessary. Signed-off-by: Toshi Kani <toshi.kani@hp.com> Cc: "H.

cleancache: forbid overriding cleancache_ops
Currently, cleancache_register_ops returns the previous value of cleancache_ops to allow chaining. However, chaining, as it is implemented now, is extremely dangerous due to possible pool id collisions. Suppose, a new cleancache driver is registered after the previous one assigned an id to a super block. If the new driver assigns the same id to another super block, which is perfectly possible, we will have two different filesystems using the same id. No matter if the new driver implements chaining or not, we are likely to get data corruption with such a configuration eventually. This patch therefore disables the ability to override cleancache_ops altogether as potentially dangerous. If there is already cleancache driver registered, all further calls to cleancache_register_ops will return EBUSY. Since no user of cleancache implements chaining, we only need to make minor changes to the code outside the cleancache core.

mm: rename __mlock_vma_pages_range() to populate_vma_page_range()
__mlock_vma_pages_range() doesn't necessarily mlock pages. It depends on
vma flags. The same codepath is used for MAP_POPULATE.
Let's rename __mlock_vma_pages_range() to populate_vma_page_range().
This patch also drops mlock_vma_pages_range() references from

watchdog: enable the new user interface of the watchdog mechanism
With the current user interface of the watchdog mechanism it is only
possible to disable or enable both lockup detectors at the same time.
This series introduces new kernel parameters and changes the semantics of
some existing kernel parameters, so that the hard lockup detector and the
soft lockup detector can be disabled or enabled individually. With this
series applied, the user interface is as follows.
- parameters in /proc/sys/kernel
. soft_watchdog
This is a new parameter to control and examine the run state of
the soft lockup detector.
. nmi_watchdog
The semantics of this parameter have changed. It can now be used
to control and examine the run state of the hard lockup detector.
. watchdog
This parameter is still available to control the run state of both
lockup detectors at the same time. If this parameter is examined,
it shows the logical OR of soft_watchdog and nmi_watchdog.
. watchdog_thresh
The semantics of this parameter are not affected by the patch.
- kernel command line parameters
. nosoftlockup
The semantics of this parameter have changed. It can now be used
to disable the soft lockup detector at boot time.
. nmi_watchdog=0 or nmi_watchdog=1
Disable or enable the hard lockup detector at boot time. The patch
introduces '=1' as a new option.
. nowatchdog
The semantics of this parameter are not affected by the patch. It
is still available to disable both lockup detectors at boot time.
Also, remove the proc_dowatchdog() function which is no longer needed.

target: simplify the target template registration API
Instead of calling target_fabric_configfs_init() + target_fabric_configfs_register() / target_fabric_configfs_deregister() target_fabric_configfs_free() from every target driver, rewrite the API so that we have simple register/unregister functions that operate on a const operations vector. This patch also fixes a memory leak in several target drivers. Several target drivers namely called target_fabric_configfs_deregister() without calling target_fabric_configfs_free(). A large part of this patch is based on earlier changes from Bart Van Assche <bart.vanassche@sandisk.com>.

Clean-up for omap PRCM (Power Reset Clock Management) and interconnects
from Tero Kristo <t-kristo@ti.com>.

regulator: Updates for v4.1
Another release, another set of regulator updates. Not much of it is
showing up in the code yet but there's been a lot of discussion going on
about how to enhance the regulator API to work better with modern SoCs
which have a microcontroller sitting between Linux and the hardware.
I'm hopeful that'll start to come through into mainline for v4.2 but
it's not quite there for v4.1 - what we do have (along with the usual
small updates is) is:
- Work from Bjorn Andersson on refactoring the configuration of
regulator loading interfaces to be useful for use with
microcontrollers, the existing interfaces were never actually useful
for anything as-is since nobody was willing to put enough data into
public code.
- A summary tree display in debugfs from Heiko Stübner.
- Support for act6000 regulators.

spi: Updates for v4.1
Only one framework update this time around, a change from Lars-Peter to
move full to pm_ops and remove the legacy bus PM ops. Otherwise it's
all driver updates:
- Make the spidev driver complain loudly if registered as spidev with
DT rather than with a compatible string, hopefully helping people
avoid making that mistake.
- Error handling and robustness fixes for the Designware and Intel MID
drivers from Andy Shevchenko.
- Substantial performance improvements for the Raspberry Pi driver from
Martin Sperl.
- Several new features for spidev_test from Adrian Remonda and Ian
Abbott.

Pull x86 asm changes from Ingo Molnar:
"There were lots of changes in this development cycle:
- over 100 separate cleanups, restructuring changes, speedups and
fixes in the x86 system call, irq, trap and other entry code, part
of a heroic effort to deobfuscate a decade old spaghetti asm code
and its C code dependencies (Denys Vlasenko, Andy Lutomirski)
- alternatives code fixes and enhancements (Borislav Petkov)
- simplifications and cleanups to the compat code (Brian Gerst)
- signal handling fixes and new x86 testcases (Andy Lutomirski)
- various other fixes and cleanups
By their nature many of these changes are risky - we tried to test
them well on many different x86 systems (there are no known
regressions), and they are split up finely to help bisection - but
there's still a fair bit of residual risk left so caveat emptor"

The most interesting bit here is irqfd/ioeventfd support for ARM and ARM64.
ARM/ARM64: fixes for live migration, irqfd and ioeventfd support (enabling
vhost, too), page aging
s390: interrupt handling rework, allowing to inject all local interrupts
via new ioctl and to get/set the full local irq state for migration
and introspection. New ioctls to access memory by virtual address,
and to get/set the guest storage keys. SIMD support.
MIPS: FPU and MIPS SIMD Architecture (MSA) support. Includes some patches
from Ralf Baechle's MIPS tree.
x86: bugfixes (notably for pvclock, the others are small) and cleanups.
Another small latency improvement for the TSC deadline timer.
