mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf
->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.

mm, page_alloc: only use per-cpu allocator for irq-safe requests
Many workloads that allocate pages are not handling an interrupt at a
time. As allocation requests may be from IRQ context, it's necessary to
disable/enable IRQs for every page allocation. This cost is the bulk of
the free path but also a significant percentage of the allocation path.
This patch alters the locking and checks such that only irq-safe
allocation requests use the per-cpu allocator. All others acquire the
irq-safe zone->lock and allocate from the buddy allocator. It relies on
disabling preemption to safely access the per-cpu structures. It could
be slightly modified to avoid soft IRQs using it but it's not clear it's
worthwhile.
This modification may slow allocations from IRQ context slightly but the
main gain from the per-cpu allocator is that it scales better for
allocations from multiple contexts. There is an implicit assumption
that intensive allocations from IRQ contexts on multiple CPUs from a
single NUMA node are rare and that the fast majority of scaling issues
are encountered in !IRQ contexts such as page faulting. It's worth
noting that this patch is not required for a bulk page allocator but it
significantly reduces the overhead.
The following is results from a page allocator micro-benchmark. Only
order-0 is interesting as higher orders do not use the per-cpu allocator

This is the alloc, free and total overhead of allocating order-0 pages
in batches of 1 page up to 16384 pages. Avoiding disabling/enabling
overhead massively reduces overhead. Alloc overhead is roughly reduced
by 14-20% in most cases. The free path is reduced by 26-46% and the
total reduction is significant.
Many users require zeroing of pages from the page allocator which is the
vast cost of allocation. Hence, the impact on a basic page faulting
benchmark is not that significant

This is from aim9 and the most notable outcome is that fault variability
is reduced by the patch. The headline improvement is small as the
overall fault cost, zeroing, page table insertion etc dominate relative
to disabling/enabling IRQs in the per-cpu allocator.
Similarly, little benefit was seen on networking benchmarks both
localhost and between physical server/clients where other costs
dominate. It's possible that this will only be noticable on very high
speed networks.
Jesper Dangaard Brouer independently tested this with a separate
microbenchmark from

Compared to baseline: 213 cycles(tsc) 53.417 ns
- against this : 184 cycles(tsc) 46.056 ns
- Saving : -29 cycles
- Very close to expected 27 cycles saving [see below [2]]
Micro benchmarking via time_bench_sample[3], we get the cost of these
operations:

Pulling cpu hotplug locks inside the page allocator is just too
dangerous. Let's remove the dependency by dropping get_online_cpus()
from drain_all_pages. This is not so simple though because now we do
not have a protection against cpu hotplug which means 2 things:
- the work item might be executed on a different cpu in worker from
unbound pool so it doesn't run on pinned on the cpu
- we have to make sure that we do not race with page_alloc_cpu_dead
calling drain_pages_zone
Disabling preemption in drain_local_pages_wq will solve the first
problem drain_local_pages will determine its local CPU from the WQ
context which will be stable after that point, page_alloc_cpu_dead is
pinned to the CPU already. The later condition is achieved by disabling
IRQs in drain_pages_zone.

mm, page_alloc: drain per-cpu pages from workqueue context
The per-cpu page allocator can be drained immediately via drain_all_pages() which sends IPIs to every CPU. In the next patch, the per-cpu allocator will only be used for interrupt-safe allocations which prevents draining it from IPI context. This patch uses workqueues to drain the per-cpu lists instead. This is slower but no slowdown during intensive reclaim was measured and the paths that use drain_all_pages() are not that sensitive to performance. This is particularly true as the path would only be triggered when reclaim is failing. It also makes a some sense to avoid storming a machine with IPIs when it's under memory pressure. Arguably, it should be further adjusted so that only one caller at a time is draining pages but it's beyond the scope of the current patch.

alloc_pages_nodemask does a number of preperation steps that determine what zones can be used for the allocation depending on a variety of factors. This is fine but a hypothetical caller that wanted multiple order-0 pages has to do the preparation steps multiple times. This patch structures __alloc_pages_nodemask such that it's relatively easy to build a bulk order-0 page allocator. There is no functional change.

mm, page_alloc: split buffered_rmqueue()
Patch series "Use per-cpu allocator for !irq requests and prepare for a bulk allocator", v5. This series is motivated by a conversation led by Jesper Dangaard Brouer at the last LSF/MM proposing a generic page pool for DMA-coherent pages. Part of his motivation was due to the overhead of allocating multiple order-0 that led some drivers to use high-order allocations and splitting them. This is very slow in some cases. The first two patches in this series restructure the page allocator such that it is relatively easy to introduce an order-0 bulk page allocator. A patch exists to do that and has been handed over to Jesper until an in-kernel users is created. The third patch prevents the per-cpu allocator being drained from IPI context as that can potentially corrupt the list after patch four is merged. The final patch alters the per-cpu alloctor to make it exclusive to !irq requests. This cuts allocation/free overhead by roughly 30%. Performance tests from both Jesper and me are included in the patch. This patch (of 4): buffered_rmqueue removes a page from a given zone and uses the per-cpu list for order-0. This is fine but a hypothetical caller that wanted multiple order-0 pages has to disable/reenable interrupts multiple times. This patch structures buffere_rmqueue such that it's relatively easy to build a bulk order-0 page allocator. There is no functional change.

mm: vmscan: move dirty pages out of the way until they're flushed
We noticed a performance regression when moving hadoop workloads from 3.10 kernels to 4.0 and 4.6. This is accompanied by increased pageout activity initiated by kswapd as well as frequent bursts of allocation stalls and direct reclaim scans. Even lowering the dirty ratios to the equivalent of less than 1% of memory would not eliminate the issue, suggesting that dirty pages concentrate where the scanner is looking. This can be traced back to recent efforts of thrash avoidance. Where 3.10 would not detect refaulting pages and continuously supply clean cache to the inactive list, a thrashing workload on 4.0+ will detect and activate refaulting pages right away, distilling used-once pages on the inactive list much more effectively. This is by design, and it makes sense for clean cache. But for the most part our workload's cache faults are refaults and its use-once cache is from streaming writes. We end up with most of the inactive list dirty, and we don't go after the active cache as long as we have use-once pages around. But waiting for writes to avoid reclaiming clean cache that *might* refault is a bad trade-off. Even if the refaults happen, reads are faster than writes. Before getting bogged down on writeback, reclaim should first look at *all* cache in the system, even active cache. To accomplish this, activate pages that are dirty or under writeback when they reach the end of the inactive LRU. The pages are marked for immediate reclaim, meaning they'll get moved back to the inactive LRU tail as soon as they're written back and become reclaimable. But in the meantime, by reducing the inactive list to only immediately reclaimable pages, we allow the scanner to deactivate and refill the inactive list with clean cache from the active list tail to guarantee forward progress.

mm: vmscan: only write dirty pages that the scanner has seen twice
Dirty pages can easily reach the end of the LRU while there are still clean pages to reclaim around. Don't let kswapd write them back just because there are a lot of them. It costs more CPU to find the clean pages, but that's almost certainly better than to disrupt writeback from the flushers with LRU-order single-page writes from reclaim. And the flushers have been woken up by that point, so we spend IO capacity on flushing and CPU capacity on finding the clean cache. Only start writing dirty pages if they have cycled around the LRU twice now and STILL haven't been queued on the IO device. It's possible that the dirty pages are so sparsely distributed across different bdis, inodes, memory cgroups, that the flushers take forever to get to the ones we want reclaimed. Once we see them twice on the LRU, we know that's the quicker way to find them, so do LRU writeback.

mm: vmscan: remove old flusher wakeup from direct reclaim path
Direct reclaim has been replaced by kswapd reclaim in pretty much all common memory pressure situations, so this code most likely doesn't accomplish the described effect anymore. The previous patch wakes up flushers for all reclaimers when we encounter dirty pages at the tail end of the LRU. Remove the crufty old direct reclaim invocation.

mm: vmscan: kick flushers when we encounter dirty pages on the LRU
Memory pressure can put dirty pages at the end of the LRU without anybody running into dirty limits. Don't start writing individual pages from kswapd while the flushers might be asleep. Unlike the old direct reclaim flusher wakeup (removed in the next patch) that flushes the number of pages just scanned, this patch wakes the flushers for all outstanding dirty pages. That seemed to perform better in a synthetic test that pushes dirty pages to the end of the LRU and into reclaim, because we know LRU aging outstrips writeback already, and this way we give younger dirty pages a headstart rather than wait until reclaim runs into them as well. It also means less plugging and risk of exhausting the struct request pool from reclaim. There is a concern that this will cause temporary files that used to get dirtied and truncated before writeback to now get written to disk under memory pressure. If this turns out to be a real problem, we'll have to revisit this and tame the reclaim flusher wakeups.

mm: vmscan: scan dirty pages even in laptop mode
Patch series "mm: vmscan: fix kswapd writeback regression".
We noticed a regression on multiple hadoop workloads when moving from
3.10 to 4.0 and 4.6, which involves kswapd getting tangled up in page
writeout, causing direct reclaim herds that also don't make progress.
I tracked it down to the thrash avoidance efforts after 3.10 that make
the kernel better at keeping use-once cache and use-many cache sorted on
the inactive and active list, with more aggressive protection of the
active list as long as there is inactive cache. Unfortunately, our
workload's use-once cache is mostly from streaming writes. Waiting for
writes to avoid potential reloads in the future is not a good tradeoff.
These patches do the following:
1. Wake the flushers when kswapd sees a lump of dirty pages. It's
possible to be below the dirty background limit and still have cache
velocity push them through the LRU. So start a-flushin'.
2. Let kswapd only write pages that have been rotated twice. This makes
sure we really tried to get all the clean pages on the inactive list
before resorting to horrible LRU-order writeback.
3. Move rotating dirty pages off the inactive list. Instead of churning
or waiting on page writeback, we'll go after clean active cache. This
might lead to thrashing, but in this state memory demand outstrips IO
speed anyway, and reads are faster than writes.
Mel backported the series to 4.10-rc5 with one minor conflict and ran a
couple of tests on it. Mix of read/write random workload didn't show
anything interesting. Write-only database didn't show much difference
in performance but there were slight reductions in IO -- probably in the
noise.
simoop did show big differences although not as big as Mel expected.
This is Chris Mason's workload that similate the VM activity of hadoop.
Mel won't go through the full details but over the samples measured
during an hour it reported

The latencies are actually completely horrific in comparison to 4.4 (and
4.10-rc5 is worse than 4.9 according to historical data for reasons Mel
hasn't analysed yet).
Still, 95% of write latency (p95-write) is halved by the series and
allocation latency is way down. Direct reclaim activity is one fifth of
what it was according to vmstats. Kswapd activity is higher but this is
not necessarily surprising. Kswapd efficiency is unchanged at 99% (99%
of pages scanned were reclaimed) but direct reclaim efficiency went from
77% to 99%
In the vanilla kernel, 627MB of data was written back from reclaim
context. With the series, no data was written back. With or without
the patch, pages are being immediately reclaimed after writeback
completes. However, with the patch, only 1/8th of the pages are
reclaimed like this.
This patch (of 5):
We have an elaborate dirty/writeback throttling mechanism inside the
reclaim scanner, but for that to work the pages have to go through
shrink_page_list() and get counted for what they are. Otherwise, we
mess up the LRU order and don't match reclaim speed to writeback.
Especially during deactivation, there is never a reason to skip dirty
pages; nothing is even trying to write them out from there. Don't mess
up the LRU order for nothing, shuffle these pages along.

userfaultfd: non-cooperative: rename *EVENT_MADVDONTNEED to *EVENT_REMOVE
Patch series "userfaultfd: non-cooperative: add madvise() event for MADV_REMOVE request". These patches add notification of madvise(MADV_REMOVE) event to non-cooperative userfaultfd monitor. The first pacth renames EVENT_MADVDONTNEED to EVENT_REMOVE along with relevant functions and structures. Using _REMOVE instead of _MADVDONTNEED describes the event semantics more clearly and I hope it's not too late for such change in the ABI. This patch (of 3): The UFFD_EVENT_MADVDONTNEED purpose is to notify uffd monitor about removal of certain range from address space tracked by userfaultfd. Hence, UFFD_EVENT_REMOVE seems to better reflect the operation semantics. Respectively, 'madv_dn' field of uffd_msg is renamed to 'remove' and the madvise_userfault_dontneed callback is renamed to userfaultfd_remove.

mm/ksm: improve deduplication of zero pages with colouring
Some architectures have a set of zero pages (coloured zero pages) instead of only one zero page, in order to improve the cache performance. In those cases, the kernel samepage merger (KSM) would merge all the allocated pages that happen to be filled with zeroes to the same deduplicated page, thus losing all the advantages of coloured zero pages. This behaviour is noticeable when a process accesses large arrays of allocated pages containing zeroes. A test I conducted on s390 shows that there is a speed penalty when KSM merges such pages, compared to not merging them or using actual zero pages from the start without breaking the COW. This patch fixes this behaviour. When coloured zero pages are present, the checksum of a zero page is calculated during initialisation, and compared with the checksum of the current canditate during merging. In case of a match, the normal merging routine is used to merge the page with the correct coloured zero page, which ensures the candidate page is checked to be equal to the target zero page. A sysfs entry is also added to toggle this behaviour, since it can potentially introduce performance regressions, especially on architectures without coloured zero pages. The default value is disabled, for backwards compatibility. With this patch, the performance with KSM is the same as with non COW-broken actual zero pages, which is also the same as without KSM.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman: "There is a lot here. A lot of these changes result in subtle user visible differences in kernel behavior. I don't expect anything will care but I will revert/fix things immediately if any regressions show up. From Seth Forshee there is a continuation of the work to make the vfs ready for unpriviled mounts. We had thought the previous changes prevented the creation of files outside of s_user_ns of a filesystem, but it turns we missed the O_CREAT path. Ooops. Pavel Tikhomirov and Oleg Nesterov worked together to fix a long standing bug in the implemenation of PR_SET_CHILD_SUBREAPER where only children that are forked after the prctl are considered and not children forked before the prctl. The only known user of this prctl systemd forks all children after the prctl. So no userspace regressions will occur. Holding earlier forked children to the same rules as later forked children creates a semantic that is sane enough to allow checkpoing of processes that use this feature. There is a long delayed change by Nikolay Borisov to limit inotify instances inside a user namespace. Michael Kerrisk extends the API for files used to maniuplate namespaces with two new trivial ioctls to allow discovery of the hierachy and properties of namespaces. Konstantin Khlebnikov with the help of Al Viro adds code that when a network namespace exits purges it's sysctl entries from the dcache. As in some circumstances this could use a lot of memory. Vivek Goyal fixed a bug with stacked filesystems where the permissions on the wrong inode were being checked. I continue previous work on ptracing across exec. Allowing a file to be setuid across exec while being ptraced if the tracer has enough credentials in the user namespace, and if the process has CAP_SETUID in it's own namespace. Proc files for setuid or otherwise undumpable executables are now owned by the root in the user namespace of their mm. Allowing debugging of setuid applications in containers to work better. A bug I introduced with permission checking and automount is now fixed. The big change is to mark the mounts that the kernel initiates as a result of an automount. This allows the permission checks in sget to be safely suppressed for this kind of mount. As the permission check happened when the original filesystem was mounted. Finally a special case in the mount namespace is removed preventing unbounded chains in the mount hash table, and making the semantics simpler which benefits CRIU. The vfs fix along with related work in ima and evm I believe makes us ready to finish developing and merge fully unprivileged mounts of the fuse filesystem. The cleanups of the mount namespace makes discussing how to fix the worst case complexity of umount. The stacked filesystem fixes pave the way for adding multiple mappings for the filesystem uids so that efficient and safer containers can be implemented" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: proc/sysctl: Don't grab i_lock under sysctl_lock. vfs: Use upper filesystem inode in bprm_fill_uid() proc/sysctl: prune stale dentries during unregistering mnt: Tuck mounts under others instead of creating shadow/side mounts. prctl: propagate has_child_subreaper flag to every descendant introduce the walk_process_tree() helper nsfs: Add an ioctl() to return owner UID of a userns fs: Better permission checking for submounts exit: fix the setns() && PR_SET_CHILD_SUBREAPER interaction vfs: open() with O_CREAT should not create inodes with unknown ids nsfs: Add an ioctl() to return the namespace type proc: Better ownership of files for non-dumpable tasks in user namespaces exec: Remove LSM_UNSAFE_PTRACE_CAP exec: Test the ptracer's saved cred to see if the tracee can gain caps exec: Don't reset euid and egid when the tracee has CAP_SETUID inotify: Convert to using per-namespace limits |

ARM: SoC driver updates
Driver updates for ARM SoCs.
A handful of driver changes this time around. The larger changes are:
- Reset drivers for hi3660 and zx2967
- AHCI driver for Davinci, acked by Tejun and brought in here due to
platform dependencies
- Cleanups of atmel-ebi (External Bus Interface)
- Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
register range on the SoCs)
- PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

ARM: SoC platform updates
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms. This release cycle the diffstat is quite nice, in that we're removing 3x the amount of code that's being added. The main reason for this is that there's a removal of camera drivers for Freescale i.MX chips (driver was removed so the device registration isn't needed any more). There's also removal of display initialization code for OMAP that is no longer needed. The rest are mostly minor tweaks and cleanups; constification on Samsung platforms, cleanup of ux500 platform data, purge of other unused platform data/device seutp on i.MX and other good stuff. New SoC support this cycle is for two Allwinner platforms, H2+ and V3s. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJYrMs4AAoJEIwa5zzehBx34LQP/j/pzJOw2cLr0iiHwNl/3jyC XFt/F6NFfPuBOCldUoMsZzD2lOR1Qbhp96fAQtDzs/HkGRVxokcHRVJC1QWozSkt 18wm8tc4HtLvjWoeXyh3zFvwl4wiqx4d4r4yxw1wZKA0uhEXrSNJu4P/RgtXH4SK TycfodE35kJ8wCxLNXYr1vaAMKgjmBkk8DAQa5t6XXBnSLGJmNAa5+vCJKab1im+ 9mOZ1EigtrkRR6eL6OJmru3MaZYLg7q+oxq5i/5NOIOZsCWq6Wk4r+5HnTg+8aVf QVs766sEjwZJ5ozZYhYucp8pvQhyatG36vwB51x1XlTA4XzAJwMEgPAtb5Pc/owU cst8d4m24Gc7oChcxlbmrqK64hpF1s5LK/ZbfdLPHaK1PS/ng/teHfVA2Q2HXwur HcHA8dDqgTVCNcCpLX1OgBUbq9S0aopuL9bdeg6q6fU8Skb49BmeHK2Iji3MZSkO 8XdY8H7oKtkwLFx18GJzmdXtH55vIXpHYMvgpjMaWAujtoqZCZ7+GHCmM3GyNCrF +KzJMVdx1lg6yYhfo4rZBWGzK2CrHvq5u5Vq7GExxhVCPsOx3mRQQ0JY/adGWU/y WTCbogwxUNbjlugffwQa+dYdF2KU2kAHAyEFDITndZmp60xJohWPYVJw+7imF5wR 0Qbcj6OvffBcaTdxKzTE =YE8v -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e. C code changes for SoC platforms.

ARM: SoC non-urgent fixes for merge window
We sometimes collect non-critical fixes that come in during the later part
of the merge window in a branch for the next release instead, and this is
that contents for v4.11.
Most of these are OMAP fixes, dealing with OMAP36/37 detection, quirks
and setup. There's also some fixes for Davinci and a Kconfig fix for SCPI
to only enable on ARM{,64}.

remoteproc updates for v4.11
This introduces support for booting the dedicated sensor core in the Qualcomm MSM8996, updates the Qualcomm ADSP and Hexagon drivers to utilize SMD subdevice helpers for properly handle shutdowns and restarts of the remoteproc, add virtio support to the ST remoteproc and refactor the Qualcomm Hexagon driver to handle variations between platforms. The support code for parsing, loading and authenticating Qualcomm firmware files (MDT) is refactored and move to drivers/soc/qcom, to allow for non-remoteproc drivers to utilize this.

- A slight behavior change of single_cmd option
- Quirks for AmigaOne X1000, Samsung Ativ Book 8, Dell AiO, ALC221 HP,
and fixes for Lewisburg controller
- Realtek ALC299, ALC1220 codecs
Others:
- USB-audio: Tascam US-16x08 DSP mixer quirk
- Intel HDMI LPE audio support for Baytrail / Cherrytrail; this
contains some updates in drm/i915 for the new platform binding
ASoC:
- Lots of updates in Intel drivers, mostly for DisplayPort and HDMI
on Skylake and onwards, as well as more Baytrail / Cherrytrail
boards support
- Channel mapping support for HDMI
- Support for AllWinner A31 and A33, Everest Semiconductor ES8328,
Nuvoton NAU8540.
