mempool: add unlikely and likely hints
Add unlikely and likely hints to the function mempool_free. It lays out the code in such a way that the common path is executed straighforward and saves a cache line.

mm, compaction: determine isolation mode only once
The conditions that control the isolation mode in isolate_migratepages_range() do not change during the iteration, so extract them out and only define the value once. This actually does have an effect, gcc doesn't optimize it itself because of cc->sync.

mm, mempolicy: remove per-process flag
PF_MEMPOLICY is an unnecessary optimization for CONFIG_SLAB users. There's no significant performance degradation to checking current->mempolicy rather than current->flags & PF_MEMPOLICY in the allocation path, especially since this is considered unlikely().

mm, mempolicy: rename slab_node for clarity
slab_node() is actually a mempolicy function, so rename it to mempolicy_slab_node() to make it clearer that it used for processes with mempolicies. At the same time, cleanup its code by saving numa_mem_id() in a local variable (since we require a node with memory, not just any node) and remove an obsolete comment that assumes the mempolicy is actually passed into the function.

mm: per-thread vma caching
This patch is a continuation of efforts trying to optimize find_vma(), avoiding potentially expensive rbtree walks to locate a vma upon faults. The original approach (https://lkml.org/lkml/2013/11/1/410), where the largest vma was also cached, ended up being too specific and random, thus further comparison with other approaches were needed. There are two things to consider when dealing with this, the cache hit rate and the latency of find_vma(). Improving the hit-rate does not necessarily translate in finding the vma any faster, as the overhead of any fancy caching schemes can be too high to consider. We currently cache the last used vma for the whole address space, which provides a nice optimization, reducing the total cycles in find_vma() by up to 250%, for workloads with good locality. On the other hand, this simple scheme is pretty much useless for workloads with poor locality. Analyzing ebizzy runs shows that, no matter how many threads are running, the mmap_cache hit rate is less than 2%, and in many situations below 1%. The proposed approach is to replace this scheme with a small per-thread cache, maximizing hit rates at a very low maintenance cost. Invalidations are performed by simply bumping up a 32-bit sequence number. The only expensive operation is in the rare case of a seq number overflow, where all caches that share the same address space are flushed. Upon a miss, the proposed replacement policy is based on the page number that contains the virtual address in question. Concretely, the following results are seen on an 80 core, 8 socket x86-64 box: 1) System bootup: Most programs are single threaded, so the per-thread scheme does improve ~50% hit rate by just adding a few more slots to the cache. +----------------+----------+------------------+ | caching scheme | hit-rate | cycles (billion) | +----------------+----------+------------------+ | baseline | 50.61% | 19.90 | | patched | 73.45% | 13.58 | +----------------+----------+------------------+ 2) Kernel build: This one is already pretty good with the current approach as we're dealing with good locality. +----------------+----------+------------------+ | caching scheme | hit-rate | cycles (billion) | +----------------+----------+------------------+ | baseline | 75.28% | 11.03 | | patched | 88.09% | 9.31 | +----------------+----------+------------------+ 3) Oracle 11g Data Mining (4k pages): Similar to the kernel build workload. +----------------+----------+------------------+ | caching scheme | hit-rate | cycles (billion) | +----------------+----------+------------------+ | baseline | 70.66% | 17.14 | | patched | 91.15% | 12.57 | +----------------+----------+------------------+ 4) Ebizzy: There's a fair amount of variation from run to run, but this approach always shows nearly perfect hit rates, while baseline is just about non-existent. The amounts of cycles can fluctuate between anywhere from ~60 to ~116 for the baseline scheme, but this approach reduces it considerably. For instance, with 80 threads: +----------------+----------+------------------+ | caching scheme | hit-rate | cycles (billion) | +----------------+----------+------------------+ | baseline | 1.06% | 91.54 | | patched | 99.97% | 14.18 | +----------------+----------+------------------+ [akpm@linux-foundation.org: fix nommu build, per Davidlohr] [akpm@linux-foundation.org: document vmacache_valid() logic] [akpm@linux-foundation.org: attempt to untangle header files] [akpm@linux-foundation.org: add vmacache_find() BUG_ON] [hughd@google.com: add vmacache_valid_mm() (from Oleg)] [akpm@linux-foundation.org: coding-style fixes] [akpm@linux-foundation.org: adjust and enhance comments] Signed-off-by: Davidlohr Bueso <davidlohr@hp.com> Reviewed-by: Rik van Riel <riel@redhat.com> Acked-by: Linus Torvalds <torvalds@linux-foundation.org> Reviewed-by: Michel Lespinasse <walken@google.com> Cc: Oleg Nesterov <oleg@redhat.com> Tested-by: Hugh Dickins <hughd@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

mm: introduce vm_ops->map_pages()
Here's new version of faultaround patchset. It took a while to tune it and collect performance data. First patch adds new callback ->map_pages to vm_operations_struct. ->map_pages() is called when VM asks to map easy accessible pages. Filesystem should find and map pages associated with offsets from "pgoff" till "max_pgoff". ->map_pages() is called with page table locked and must not block. If it's not possible to reach a page without blocking, filesystem should skip it. Filesystem should use do_set_pte() to setup page table entry. Pointer to entry associated with offset "pgoff" is passed in "pte" field in vm_fault structure. Pointers to entries for other offsets should be calculated relative to "pte". Currently VM use ->map_pages only on read page fault path. We try to map FAULT_AROUND_PAGES a time. FAULT_AROUND_PAGES is 16 for now. Performance data for different FAULT_AROUND_ORDER is below. TODO: - implement ->map_pages() for shmem/tmpfs; - modify get_user_pages() to be able to use ->map_pages() and implement mmap(MAP_POPULATE|MAP_NONBLOCK) on top. ========================================================================= Tested on 4-socket machine (120 threads) with 128GiB of RAM. Few real-world workloads. The sweet spot for FAULT_AROUND_ORDER here is somewhere between 3 and 5.

tools/vm/page-types.c: page-cache sniffing feature
After this patch 'page-types' can walk over a file's mappings and
analyze populated page cache pages mostly without disturbing its state.
It maps chunk of file, marks VMA as MADV_RANDOM to turn off readahead,
pokes VMA via mincore() to determine cached pages, triggers page-fault
only for them, and finally gathers information via pagemap/kpageflags.
Before unmap it marks VMA as MADV_SEQUENTIAL for ignoring reference
bits.
usage: page-types -f <path>
If <path> is directory it will analyse all files in all subdirectories.
Symlinks are not followed as well as mount points. Hardlinks aren't
handled, they'll be dumped as many times as they are found. Recursive
walk brings all dentries into dcache and populates page cache of
block-devices aka 'Buffers'.
Probably it's worth to add ioctl for dumping file page cache as array of
PFNs as a replacement for this hackish juggling with
mmap/madvise/mincore/pagemap. Also recursive walk could be replaced
with dumping cached inodes via some ioctl or debugfs interface followed
by openning them via open_by_handle_at, this would fix hardlinks
handling and unneeded population of dcache and buffers. This interface
might be used as data source for constructing readahead plans and for
background optimizations of actively used files.
collateral changes:
+ fix 64-bit LFS: define _FILE_OFFSET_BITS instead of _LARGEFILE64_SOURCE
+ replace lseek + read with single pread
+ make show_page_range() reusable after flush

mm: revert "thp: make MADV_HUGEPAGE check for mm->def_flags"
The main motivation behind this patch is to provide a way to disable THP
for jobs where the code cannot be modified, and using a malloc hook with
madvise is not an option (i.e. statically allocated data). This patch
allows us to do just that, without affecting other jobs running on the
system.
We need to do this sort of thing for jobs where THP hurts performance,
due to the possibility of increased remote memory accesses that can be
created by situations such as the following:
When you touch 1 byte of an untouched, contiguous 2MB chunk, a THP will
be handed out, and the THP will be stuck on whatever node the chunk was
originally referenced from. If many remote nodes need to do work on
that same chunk, they'll be making remote accesses.
With THP disabled, 4K pages can be handed out to separate nodes as
they're needed, greatly reducing the amount of remote accesses to
memory.
This patch is based on some of my work combined with some
suggestions/patches given by Oleg Nesterov. The main goal here is to
add a prctl switch to allow us to disable to THP on a per mm_struct
basis.
Here's a bit of test data with the new patch in place...

mm/compaction: check pageblock suitability once per pageblock
isolation_suitable() and migrate_async_suitable() is used to be sure that this pageblock range is fine to be migragted. It isn't needed to call it on every page. Current code do well if not suitable, but, don't do well when suitable. 1) It re-checks isolation_suitable() on each page of a pageblock that was already estabilished as suitable. 2) It re-checks migrate_async_suitable() on each page of a pageblock that was not entered through the next_pageblock: label, because last_pageblock_nr is not otherwise updated. This patch fixes situation by 1) calling isolation_suitable() only once per pageblock and 2) always updating last_pageblock_nr to the pageblock that was just checked. Additionally, move PageBuddy() check after pageblock unit check, since pageblock check is the first thing we should do and makes things more simple.

mm/compaction: change the timing to check to drop the spinlock
It is odd to drop the spinlock when we scan (SWAP_CLUSTER_MAX - 1) th pfn page. This may results in below situation while isolating migratepage. 1. try isolate 0x0 ~ 0x200 pfn pages. 2. When low_pfn is 0x1ff, ((low_pfn+1) % SWAP_CLUSTER_MAX) == 0, so drop the spinlock. 3. Then, to complete isolating, retry to aquire the lock. I think that it is better to use SWAP_CLUSTER_MAX th pfn for checking the criteria about dropping the lock. This has no harm 0x0 pfn, because, at this time, locked variable would be false.

mm/compaction: do not call suitable_migration_target() on every page
suitable_migration_target() checks that pageblock is suitable for migration target. In isolate_freepages_block(), it is called on every page and this is inefficient. So make it called once per pageblock. suitable_migration_target() also checks if page is highorder or not, but it's criteria for highorder is pageblock order. So calling it once within pageblock range has no problem.

Purpose of compaction is to get a high order page. Currently, if we find high-order page while searching migration target page, we break it to order-0 pages and use them as migration target.

mm: exclude memoryless nodes from zone_reclaim
We had a report about strange OOM killer strikes on a PPC machine although there was a lot of swap free and a tons of anonymous memory which could be swapped out. In the end it turned out that the OOM was a side effect of zone reclaim which wasn't unmapping and swapping out and so the system was pushed to the OOM. Although this sounds like a bug somewhere in the kswapd vs. zone reclaim vs. direct reclaim interaction numactl on the said hardware suggests that the zone reclaim should not have been set in the first place: node 0 cpus: 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 node 0 size: 0 MB node 0 free: 0 MB node 2 cpus: node 2 size: 7168 MB node 2 free: 6019 MB node distances: node 0 2 0: 10 40 2: 40 10 So all the CPUs are associated with Node0 which doesn't have any memory while Node2 contains all the available memory. Node distances cause an automatic zone_reclaim_mode enabling. Zone reclaim is intended to keep the allocations local but this doesn't make any sense on the memoryless nodes. So let's exclude such nodes for init_zone_allows_reclaim which evaluates zone reclaim behavior and suitable reclaim_nodes.

mm/vmscan: do not check compaction_ready on promoted zones
We abort direct reclaim if we find the zone is ready for compaction. Sometimes the zone is just a promoted highmem zone to force a scan of highmem, which is not the intended zone the caller want to allocate a page from. In this situation, setting aborted_reclaim to indicate the caller turned back to retry the allocation is waste of time and could cause a loop in __alloc_pages_slowpath(). This patch does not check compaction_ready() on promoted zones to avoid the above situation. Only set aborted_reclaim if the caller intended zone is ready for compaction.

mm: move mmu notifier call from change_protection to change_pmd_range
The NUMA scanning code can end up iterating over many gigabytes of unpopulated memory, especially in the case of a freshly started KVM guest with lots of memory. This results in the mmu notifier code being called even when there are no mapped pages in a virtual address range. The amount of time wasted can be enough to trigger soft lockup warnings with very large KVM guests. This patch moves the mmu notifier call to the pmd level, which represents 1GB areas of memory on x86-64. Furthermore, the mmu notifier code is only called from the address in the PMD where present mappings are first encountered. The hugetlbfs code is left alone for now; hugetlb mappings are not relocatable, and as such are left alone by the NUMA code, and should never trigger this problem to begin with.

Sasha reported the following bug using trinity kernel BUG at mm/mprotect.c:149! invalid opcode: 0000 [#1] PREEMPT SMP DEBUG_PAGEALLOC Dumping ftrace buffer: (ftrace buffer empty) Modules linked in: CPU: 20 PID: 26219 Comm: trinity-c216 Tainted: G W 3.14.0-rc5-next-20140305-sasha-00011-ge06f5f3-dirty #105 task: ffff8800b6c80000 ti: ffff880228436000 task.ti: ffff880228436000 RIP: change_protection_range+0x3b3/0x500 Call Trace: change_protection+0x25/0x30 change_prot_numa+0x1b/0x30 task_numa_work+0x279/0x360 task_work_run+0xae/0xf0 do_notify_resume+0x8e/0xe0 retint_signal+0x4d/0x92 The VM_BUG_ON was added in -mm by the patch "mm,numa: reorganize change_pmd_range". The race existed without the patch but was just harder to hit. The problem is that a transhuge check is made without holding the PTL. It's possible at the time of the check that a parallel fault clears the pmd and inserts a new one which then triggers the VM_BUG_ON check. This patch removes the VM_BUG_ON but fixes the race by rechecking transhuge under the PTL when marking page tables for NUMA hinting and bailing if a race occurred. It is not a problem for calls to mprotect() as they hold mmap_sem for write.

ntfs: logging clean-up
- Convert spinlock/static array to va_format (inspired by Joe Perches help on previous logging patches). - Convert printk(KERN_ERR to pr_warn in __ntfs_warning. - Convert printk(KERN_ERR to pr_err in __ntfs_error. - Convert printk(KERN_DEBUG to pr_debug in __ntfs_debug. (Note that __ntfs_debug is still guarded by #if DEBUG) - Improve !DEBUG to parse all arguments (Joe Perches). - Sparse pr_foo() conversions in super.c NTFS, NTFS-fs prefixes as well as 'warning' and 'error' were removed : pr_foo() automatically adds module name and error level is already specified.

IOMMU Upates for Linux v3.15
This time a few more updates queued up.
* Rework VT-d code to support ACPI devices
* Improvements for memory and PCI hotplug support
in the VT-d driver
* Device-tree support for OMAP IOMMU
* Convert OMAP IOMMU to use devm_* interfaces
* Fixed PASID support for AMD IOMMU
* Other random cleanups and fixes for OMAP, ARM-SMMU
and SHMOBILE IOMMU
Most of the changes are in the VT-d driver because some rework was
necessary for better hotplug and ACPI device support.

ARM: SoC: late cleanups
These could not be part of the first cleanup branch, because they either
came too late in the cycle, or they have dependencies on other branches.
Important changes are:
* The integrator platform is almost multiplatform capable after
some reorganization (Linus Walleij)
* Minor cleanups on Zynq (Michal Simek)
* Lots of changes for Exynos and other Samsung platforms, including
further preparations for multiplatform support and the clocks bindings
are rearranged.

ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support for new SoCs, boards and devices without changing kernel source. The plan is still to move the devicetree files out of the kernel tree and reduce the amount of churn going on here, but we keep finding reasons to delay doing that. Changes are really all over the place, with little sticking out particularly. We have contributions from a total of 116 people in this branch. Unfortunately, the size of this branch also causes a significant number of conflicts at the moment, typically when subsystem maintainers merge patches that change the driver at the same time as the dts files. In most cases this could be avoided because the dts changes are supposed to be compatible in both ways, and we are asking everyone to send ARM dts changes through our tree only. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/11WCrR//JCVInAQIIyRAA0DjdNNQ/A4G2i1nZCiTFH6a4oZy4JarN ATVPkW/V8avhh+yVNe5FWA44Xe6CDC5TXwMaIsbK+w3Iclj3fplh/MsBkQ9ZT9Sl LAjJoOjuYucCeDy0WLVioRKZ4PJEDoCu/oZTauIMnmWCOCRxLYpOM3FkAT9oN/Ti lswpTSLiV1/U3ZSI4M3qn+Sx1VJL8c/hAIWbvf5if2diYkWPk3VOSKyxmD9zLWdD Iqtb79J+ETVeOIM4sHnx79cG4ZCdpOfRAl7qx6hkJu0YATXESxWhpXVE2McTJuzM qHKsRRNSfsfSWPeF4angll9o06X/qgdT6C4P2dfH49lGeG7llOttw3OaCx3hWCTe U5bt26qtbwG2ZbzocaqvideP+rbpQrCH2vdO1embPv5Lu6peMoBWjxy6twSVXJBG LIymJ0IbiGYxL7BReGqRXt6ehy0BDWBeTSTdsGqgEl2TnxHuS/kgGfJc4D5riiEk aRPVq10p/k+yo4BZtq2GqXIOG6cqkIQ5lhl5Tg9+MfUlquAONqJP70FgRJDBIw9L 9uJp71bgSsA6eYg2tXoqJtpdjKplDWavgtACzIkFg2qFLyYmKvx+F0AXbeTIsrri /mIchTyG+dgiIjWvj/Xsf7jhrdzRcl3uKsJwFmk927pIsh24HV8T+LKgHrf+sVcO qEsEnKGYA6s= =zl/N -----END PGP SIGNATURE----- Merge tag 'dt-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree changes from Arnd Bergmann: "A large part of the arm-soc patches are nowadays DT changes, adding support for new SoCs, boards and devices without changing kernel source.

defconfig changes here this time, and a significant number of Renesas
shmobile changes, as Renesas is still in the process of deprecating

These cleanup patches are mainly move stuff around and should all
be harmless. They are mainly split out so that other branches can
be based on top to avoid conflicts.
Notable changes are:
* We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no

Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups from Arnd Bergmann:
"These cleanup patches are mainly move stuff around and should all be
harmless. They are mainly split out so that other branches can be
based on top to avoid conflicts.
Notable changes are:
- We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
longer used (Uwe Kleine-König)
- The Qualcomm MSM platform is split out into legacy mach-msm and
new-style mach-qcom, to allow easier maintainance of the new

ARM: SoC non-critical bug fixes for 3.15
Lots of isolated bug fixes that were not found to be important enough to be submitted before the merge window or backported into stable kernels. The vast majority of these came out of Arnd's randconfig testing and just prevents running into build-time bugs in configurations that we do not care about in practice. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/yEmCrR//JCVInAQIDsBAAu9uUC/uuc77953rsRqXPOCqjG4Q4g7Y+ HGxuztTGGJN6eglK7+aRKbmSlZck6KQykevm+OYnoINcGyazXmajkUnbaVvgNCU9 iRyRLkLjilDWBQXY5Ou3wK2WgyI4pMokRYIkp+MpQHQ5IlvJ5707IYj+FswdK5kT npbcP+L5oJ13afVnI18uflapr2ecXGdvfuEZw3sWpKcfefutxmEVYzRUBkNgj5Pd bva9GcWuA/ymRJR1XQmXh7EE+kqzGX5P0hFfaQsgtUwvY2Bv3fNia+GMLrf6pUGb Pl3rxyfo9VKoW0gbeVB7sk1rHTgh6ay2T8PBSz5dpyoR4A1n8BZQXPjUd7fBKv97 VRWMXRQz5sQ05FnvJFlV5CcYikf8GFOPooUhgY7Fo1sdoDawkAOQ1AJ4yhPsx86u V/S3o3pMWqDGnFMFmS95iAWW7Ru66XVYsPJnFktiLXt6SLlSAY52DzV6HlStF4hi O9dsIi5TsOxYhSWpMFZCxHK/I805zEjGOAyTYnCQB6Lwadg0mUiwdRJvp0YzcdDM X1mCsz8yHM3bbhvkxbqzwnBNgz24TkDPA8IvUGFtyxGF+5m8MgAzIKcGc4PKI6Gg I9M0oechC2dusvfflXFinvRhZMHMHi8+t58b/+29KrsacnE5vDmBFzeWGUkCXs5q oo4cWe14m6U= =KRJL -----END PGP SIGNATURE----- Merge tag 'fixes-non-critical-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC non-critical bug fixes from Arnd Bergmann: "Lots of isolated bug fixes that were not found to be important enough to be submitted before the merge window or backported into stable kernels.

Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm
Pull ARM changes from Russell King:
- Perf updates from Will Deacon:
- Support for Qualcomm Krait processors (run perf on your phone!)
- Support for Cortex-A12 (run perf stat on your FPGA!)
- Support for perf_sample_event_took, allowing us to automatically decrease
the sample rate if we can't handle the PMU interrupts quickly enough
(run perf record on your FPGA!).
- Basic uprobes support from David Long:
This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
- ARMv7M (microcontroller) updates from Uwe Kleine-König
- OMAP DMA updates (recently added Vinod's Ack even though they've been
sitting in linux-next for a few months) to reduce the reliance of
omap-dma on the code in arch/arm.
- SA11x0 changes from Dmitry Eremin-Solenikov and Alexander Shiyan
- Support for Cortex-A12 CPU
- Align support for ARMv6 with ARMv7 so they can cooperate better in a
single zImage.
- Addition of first AT_HWCAP2 feature bits for ARMv8 crypto support.
- Removal of IRQ_DISABLED from various ARM files
- Improved efficiency of virt_to_page() for single zImage
- Patch from Ulf Hansson to permit runtime PM callbacks to be available for
AMBA devices for suspend/resume as well.
- Finally kill asm/system.h on ARM.
