scripts/spelling.txt: add "an user" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt: an user||a user an userspace||a userspace I also added "userspace" to the list since it is a common word in Linux. I found some instances for "an userfaultfd", but I did not add it to the list. I felt it is endless to find words that start with "user" such as "userland" etc., so must draw a line somewhere.

zram: extend zero pages to same element pages
The idea is that without doing more calculations we extend zero pages to same element pages for zram. zero page is special case of same element page with zero element. 1. the test is done under android 7.0 2. startup too many applications circularly 3. sample the zero pages, same pages (none-zero element) and total pages in function page_zero_filled the result is listed as below: ZERO SAME TOTAL 36214 17842 598196 ZERO/TOTAL SAME/TOTAL (ZERO+SAME)/TOTAL ZERO/SAME AVERAGE 0.060631909 0.024990816 0.085622726 2.663825038 STDEV 0.00674612 0.005887625 0.009707034 2.115881328 MAX 0.069698422 0.030046087 0.094975336 7.56043956 MIN 0.03959586 0.007332205 0.056055193 1.928985507 from the above data, the benefit is about 2.5% and up to 3% of total swapout pages. The defect of the patch is that when we recovery a page from non-zero element the operations are low efficient for partial read. This patch extends zero_page to same_page so if there is any user to have monitored zero_pages, he will be surprised if the number is increased but it's not harmful, I believe.

mm, madvise: fail with ENOMEM when splitting vma will hit max_map_count
If madvise(2) advice will result in the underlying vma being split and the number of areas mapped by the process will exceed /proc/sys/vm/max_map_count as a result, return ENOMEM instead of EAGAIN. EAGAIN is returned by madvise(2) when a kernel resource, such as slab, is temporarily unavailable. It indicates that userspace should retry the advice in the near future. This is important for advice such as MADV_DONTNEED which is often used by malloc implementations to free memory back to the system: we really do want to free memory back when madvise(2) returns EAGAIN because slab allocations (for vmas, anon_vmas, or mempolicies) cannot be allocated. Encountering /proc/sys/vm/max_map_count is not a temporary failure, however, so return ENOMEM to indicate this is a more serious issue. A followup patch to the man page will specify this behavior.

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.

watchdog: s3c2410: Fix infinite interrupt in soft mode
In soft (no-reboot) mode, the driver self-pings watchdog upon expiration of an interrupt. However the interrupt itself was not cleared thus on first hit, the system enters infinite interrupt handling loop. On Odroid U3 (Exynos4412), when booted with s3c2410_wdt.soft_noboot=1 argument the console is flooded: # killall -9 watchdog [ 60.523760] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq) [ 60.536744] s3c2410-wdt 10060000.watchdog: watchdog timer expired (irq) Fix this by writing something to the WTCLRINT register to clear the interrupt. The register WTCLRINT however appeared in S3C6410 so a new watchdog quirk and flavor are needed.

ARM: DT updates for v4.11
A total of 380 patches this time, mostly adding support for more hardware
in the device tree descriptions. There is not much exciting here for 4.11,
but I've tried my best to condense the information from the pull requests
I got into a readable summary.
Noteworthy changes to existing platforms include:
- The GIC memory map was a bit wrong almost everywhere and now
gets fixed up
- The Allwinner platforms convert to the generic pinmux properties

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.

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. Finally it brings some cleanups to the remoteproc core. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJYrem5AAoJEAsfOT8Nma3FUD0QALlYbOa4xzG6m5V8mMY1TeGD 1nSF7pntk81wKLiNbEduXp6hTu35NZb0j8lOStmF6A4yIp5GKzKWgRWknWm56N2y IfF/3ED3TcbMHeHbs9GewyXH8l3VspeqFXqQmykLbRBWywjbIq0V1NZOrNCooHrq 9atQ5LGtB+doqkIj7cKoaM9V+gVx5FPL8w6ZtVMWfbMzNZEoKBpMJSvWus+UVPbF riizz4DD/+YqNNw9Tud4zNi+bTT+d29DMNOmjbH81vb0nsrcrj7wyR7ib/ECjmSA XVEItWJGtWtQyZpgWfP+DU/ZcdjnwwUZOPiRsCyRmbtrhphwk9C8Lc/PuaNrobqx hjfCP//f+B7XVNBmkWgmkRQh4XTllkgXo/dMn3FsRwxtvtBJ9mtyCIS/cZJjPcXK 5r7PxOGKDyzX640mRsIBVDCtiSRqIZ7/XiRvE5s/X1q2NPEfotLFo50ZgdddaxPa kiqAF9G9h+4mQyYhmk4+SPyL4hYCFa8FAQkK7K01fLgQPVI0J4hm1JBm7AMBpDhK k6xyPOpPOaTKTja9WGFde4gtjlLvIE2weBB+02vXL7n7/M8w8j0bDXUKyFx98Ejj sKPGvQXtCndSNagM1EnkgZm3xbPyWPvgtD2VUvsZAlr3Td/N0qhEl4o7nLsK3ypU ihiSLKhF+V5ReeKljI3z =vAKB -----END PGP SIGNATURE----- Merge tag 'rproc-v4.11' of git://github.com/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "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.

This is the bulk of GPIO changes for the v4.11 cycle
Core changes:
- Augment fwnode_get_named_gpiod() to configure the GPIO pin
immediately after requesting it like all other APIs do.
This is a treewide change also updating all users.
- Pass a GPIO label down to gpiod_request() from
fwnode_get_named_gpiod(). This makes debugfs and the userspace
ABI correctly reflect the current in-kernel consumer of a pin
taken using this abstraction. This is a treewide change also
updating all users.
- Rename devm_get_gpiod_from_child() to
devm_fwnode_get_gpiod_from_child() to reflect the fact that this
function is operating on a fwnode object. This is a treewide
change also updating all users.
- Make it possible to take multiple GPIOs in a single hog of device
tree hogs.
- The refactorings switching GPIO chips to use the .set_config()
callback using standard pin control properties and providing
a backend into the pin control subsystem that were also merged
into the pin control tree naturally appear here too.
Testing instrumentation:
- A whole slew of cleanups and improvements to the mockup GPIO
driver. We now have an extended userspace test exercising the
subsystem, and we can inject interrupts etc from userspace
to fully test the core GPIO functionality.
New drivers:
- New driver for the Cortina Systems Gemini GPIO controller.
- New driver for the Exar XR17V352/354/358 chips.
- New driver for the ACCES PCI-IDIO-16 PCI GPIO card.
Driver changes:
- RCAR: set the irqchip parent device, add fine-grained runtime
PM support.
- pca953x: support optional RESET control line on the chip.
- DaVinci: cleanups and simplifications. Add support for multiple
instances.
- .set_multiple() and naming of lines on more or less all of the
ISA/PCI GPIO controllers.
- mcp23s08: refactored to use regmap as a first step to further
rewrites and modernizations.

4.11 is going to be a relatively large release for KVM, with a little over
200 commits and noteworthy changes for most architectures.
* ARM:
- GICv3 save/restore
- cache flushing fixes
- working MSI injection for GICv3 ITS
- physical timer emulation
* MIPS:
- various improvements under the hood
- support for SMP guests
- a large rewrite of MMU emulation. KVM MIPS can now use MMU notifiers
to support copy-on-write, KSM, idle page tracking, swapping, ballooning
and everything else. KVM_CAP_READONLY_MEM is also supported, so that
writes to some memory regions can be treated as MMIO. The new MMU also
paves the way for hardware virtualization support.
* PPC:
- support for POWER9 using the radix-tree MMU for host and guest
- resizable hashed page table
- bugfixes.
* s390: expose more features to the guest
- more SIMD extensions
- instruction execution protection
- ESOP2
* x86:
- improved hashing in the MMU
- faster PageLRU tracking for Intel CPUs without EPT A/D bits
- some refactoring of nested VMX entry/exit code, preparing for live
migration support of nested hypervisors
- expose yet another AVX512 CPUID bit
- host-to-guest PTP support
- refactoring of interrupt injection, with some optimizations thrown in
and some duct tape removed.
- remove lazy FPU handling
- optimizations of user-mode exits
- optimizations of vcpu_is_preempted() for KVM guests
* generic:
- alternative signaling mechanism that doesn't pound on tsk->sighand->siglock

zram: remove obsolete sysfs attrs
We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.

mm, thp: add new defer+madvise defrag option
There is no thp defrag option that currently allows MADV_HUGEPAGE
regions to do direct compaction and reclaim while all other thp
allocations simply trigger kswapd and kcompactd in the background and
fail immediately.
The "defer" setting simply triggers background reclaim and compaction
for all regions, regardless of MADV_HUGEPAGE, which makes it unusable
for our userspace where MADV_HUGEPAGE is being used to indicate the
application is willing to wait for work for thp memory to be available.
The "madvise" setting will do direct compaction and reclaim for these
MADV_HUGEPAGE regions, but does not trigger kswapd and kcompactd in the
background for anybody else.
For reasonable usage, there needs to be a mesh between the two options.
This patch introduces a fifth mode, "defer+madvise", that will do direct
reclaim and compaction for MADV_HUGEPAGE regions and trigger background
reclaim and compaction for everybody else so that hugepages may be
available in the near future.
A proposal to allow direct reclaim and compaction for MADV_HUGEPAGE
regions as part of the "defer" mode, making it a very powerful setting
and avoids breaking userspace, was offered:
http://marc.info/?t=148236612700003
This additional mode is a compromise.
A second proposal to allow both "defer" and "madvise" to be selected at
the same time was also offered:
http://marc.info/?t=148357345300001.
This is possible, but there was a concern that it might break existing
userspaces the parse the output of the defrag mode, so the fifth option
was introduced instead.
This patch also cleans up the helper function for storing to "enabled"
and "defrag" since the former supports three modes while the latter
supports five and triple_flag_store() was getting unnecessarily messy.

slub: make sysfs directories for memcg sub-caches optional
SLUB creates a per-cache directory under /sys/kernel/slab which hosts a bunch of debug files. Usually, there aren't that many caches on a system and this doesn't really matter; however, if memcg is in use, each cache can have per-cgroup sub-caches. SLUB creates the same directories for these sub-caches under /sys/kernel/slab/$CACHE/cgroup. Unfortunately, because there can be a lot of cgroups, active or draining, the product of the numbers of caches, cgroups and files in each directory can reach a very high number - hundreds of thousands is commonplace. Millions and beyond aren't difficult to reach either. What's under /sys/kernel/slab is primarily for debugging and the information and control on the a root cache already cover its sub-caches. While having a separate directory for each sub-cache can be helpful for development, it doesn't make much sense to pay this amount of overhead by default. This patch introduces a boot parameter slub_memcg_sysfs which determines whether to create sysfs directories for per-memcg sub-caches. It also adds CONFIG_SLUB_MEMCG_SYSFS_ON which determines the boot parameter's default value and defaults to 0.
