mm, compaction: remove redundant watermark check in compact_finished()
When detecting whether compaction has succeeded in forming a high-order page, __compact_finished() employs a watermark check, followed by an own search for a suitable page in the freelists. This is not ideal for two reasons: - The watermark check also searches high-order freelists, but has a less strict criteria wrt fallback. It's therefore redundant and waste of cycles. This was different in the past when high-order watermark check attempted to apply reserves to high-order pages. - The watermark check might actually fail due to lack of order-0 pages. Compaction can't help with that, so there's no point in continuing because of that. It's possible that high-order page still exists and it terminates. This patch therefore removes the watermark check. This should save some cycles and terminate compaction sooner in some cases.

mm, compaction: reorder fields in struct compact_control
Patch series "try to reduce fragmenting fallbacks", v3.
Last year, Johannes Weiner has reported a regression in page mobility
grouping [1] and while the exact cause was not found, I've come up with
some ways to improve it by reducing the number of allocations falling
back to different migratetype and causing permanent fragmentation.
The series was tested with mmtests stress-highalloc modified to do
GFP_KERNEL order-4 allocations, on 4.9 with "mm, vmscan: fix zone
balance check in prepare_kswapd_sleep" (without that, kcompactd indeed
wasn't woken up) on UMA machine with 4GB memory. There were 5 repeats
of each run, as the extfrag stats are quite volatile (note the stats
below are sums, not averages, as it was less perl hacking for me).
Success rate are the same, already high due to the low allocation order
used, so I'm not including them.
Compaction stats:
(the patches are stacked, and I haven't measured the non-functional-changes
patches separately)
patch 1 patch 2 patch 3 patch 4 patch 7 patch 8
Compaction stalls 22449 24680 24846 19765 22059 17480
Compaction success 12971 14836 14608 10475 11632 8757
Compaction failures 9477 9843 10238 9290 10426 8722

fix braino in generic_file_read_iter()
Wrong sign of iov_iter_revert() argument. Unfortunately, slipped through the testing, since most of the time we don't do anything to the iterator afterwards and potential oops on walking the iter->iov too far backwards is too infrequent to be easily triggered. Add a sanity check in iov_iter_revert() to catch bugs like this one; fortunately, the same braino hadn't happened in other callers, but we'd better have a warning if such thing crops up.

- A series fixing up mtip32xx for blk-mq scheduling, removing a
bandaid we previously had in place for this. From me.
- A regression fix for this series, fixing a case where we wait on
workqueue flushing from an invalid (non-blocking) context. From me.
- A fix/optimization from Ming, ensuring that we don't both quiesce
and freeze a queue at the same time.
- A fix from Peter on lock ordering for CPU hotplug. Not a real
problem right now, but will be once the CPU hotplug rework goes in.
- A series from Omar, cleaning up out blk-mq debugfs support, and
adding support for exporting info from schedulers in debugfs as
well. This is really useful in debugging stalls or livelocks. From

refcount: change EXPORT_SYMBOL markings
Now that kref is using the refcount apis, the _GPL markings are getting exported to places that it previously wasn't. Now kref.h is GPLv2 licensed, so any non-GPL code using it better be talking to some lawyers, but changing api markings isn't considered "nice", so let's fix this up.

libnvdimm for 4.12
* Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. * Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. * 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. * ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes. Acknowledgements that came after the branch was pushed: commmit |

Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1. And it's a big one, adding about 350k new lines of crap^Wcode, mostly all in a big dump of media drivers from Intel. But there's other new drivers in here as well, yet-another-wifi driver, new IIO drivers, and a new crypto accelerator. We also deleted a bunch of stuff, mostly in patch cleanups, but also the Android ION code has shrunk a lot, and the Android low memory killer driver was finally deleted, much to the celebration of the -mm developers.

We've got ten GFS2 patches for this merge window.
1. Andreas Gruenbacher wrote a patch to replace the deprecated
call to rhashtable_walk_init with rhashtable_walk_enter.
2. Andreas also wrote a patch to eliminate redundant code in
two of our debugfs sequence files.
3. Andreas also cleaned up the rhashtable key ugliness Linus
pointed out during this cycle, following Linus's suggestions.
4. Andreas also wrote a patch to take advantage of his new
function rhashtable_lookup_get_insert_fast. This makes glock
lookup faster and more bullet-proof.
5. Andreas also wrote a patch to revert a patch in the evict
path that caused occasional deadlocks, and is no longer
needed.
6. Andrew Price wrote a patch to re-enable fallocate for the
rindex system file to enable gfs2_grow to grow properly on
secondary file system grow operations.
7. I wrote a patch to initialize an inode number field to make
certain kernel trace points more understandable.
8. I also wrote a patch that makes GFS2 file system "withdraw"
work more like it should by ignoring operations after a
withdraw that would formerly cause a BUG() and kernel panic.
9. I also reworked the entire truncate/delete algorithm,
scrapping the old recursive algorithm in favor of a new
non-recursive algorithm. This was done for performance:
This way, GFS2 no longer needs to lock multiple resource
groups while doing truncates and deletes of files that cross
multiple resource group boundaries, allowing for better
parallelism. It also solves a problem whereby deleting large
files would request a large chunk of kernel memory, which
resulted in a get_page_from_freelist warning.
10. Due to a regression found during testing, I added a new
patch to correct "GFS2: Prevent BUG from occurring when
normal Withdraws occur".

- Andrew Price wrote a patch to re-enable fallocate for the rindex
system file to enable gfs2_grow to grow properly on secondary file
system grow operations.
- I wrote a patch to initialize an inode number field to make certain
kernel trace points more understandable.
- I also wrote a patch that makes GFS2 file system "withdraw" work
more like it should by ignoring operations after a withdraw that
would formerly cause a BUG() and kernel panic.
- I also reworked the entire truncate/delete algorithm, scrapping the
old recursive algorithm in favor of a new non-recursive algorithm.
This was done for performance: This way, GFS2 no longer needs to
lock multiple resource groups while doing truncates and deletes of
files that cross multiple resource group boundaries, allowing for
better parallelism. It also solves a problem whereby deleting large
files would request a large chunk of kernel memory, which resulted
in a get_page_from_freelist warning.
- Due to a regression found during testing, I added a new patch to
correct 'GFS2: Prevent BUG from occurring when normal Withdraws
occur'."

which I bisected to a subtle side-effect of a totally benign mm patch
("mm, vmalloc: properly track vmalloc users") which caused a header
include chain deviation - asm/mmu.h using NR_CPUS before including
linux/threads.h
Fix that by adding the dependnet header and while it at fix a related
header to include linux headers aheads of asm headers as sometimes that
slso triggers such issues !

powerpc updates for 4.12 part 1.
Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
virtual address space, but a process can request access to the full 512TB by
passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and runtime.
- Several small fixes and cleanups to the kprobes code, as well as support for
KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts, correctly treating
them as NMIs, giving them a dedicated stack and using a new hypervisor call
to trigger them, all of which should aid debugging and robustness.
Many fixes and other minor enhancements.

char/misc patches for 4.12-rc1
Here is the big set of new char/misc driver drivers and features for 4.12-rc1. There's lots of new drivers added this time around, new firmware drivers from Google, more auxdisplay drivers, extcon drivers, fpga drivers, and a bunch of other driver updates. Nothing major, except if you happen to have the hardware for these drivers, and then you will be happy :) All of these have been in linux-next for a while with no reported issues.

drm: Document code of conduct
freedesktop.org has adopted a formal&enforced code of conduct: https://www.fooishbar.org/blog/fdo-contributor-covenant/ https://www.freedesktop.org/wiki/CodeOfConduct/ Besides formalizing things a bit more I don't think this changes anything for us, we've already peer-enforced respectful and constructive interactions since a long time. But it's good to document things properly. v2: Drop confusing note from commit message and clarify the grammer (Chris, Alex and others).

drm/tegra: Changes for v4.12-rc1
This contains various fixes to the host1x driver as well as a plug for a leak of kernel pointers to userspace. A fairly big addition this time around is the Video Image Composer (VIC) support that can be used to accelerate some 2D and image compositing operations. Furthermore the driver now supports FB modifiers, so we no longer rely on a custom IOCTL to set those. Finally this contains a few preparatory patches for Tegra186 support which unfortunately didn't quite make it this time, but will hopefully be ready for v4.13. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAljmxI8THHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zocZaD/9AaoXn19oEPYiWx+MjIAkhBiYEw+oq RrJ1uVisZIx8Y+ftVtwURLh3HS7SXg3F3mjJxfJVxqqlGfTCry0eiru1qbAbkwC2 ebStjdBBnAhMws22Dba5R5aHh21b1px/fj9u+jtiqcKgWzB28D+jH6G4ViTzOgXs TT1inq5SQfpL3e0+ovmVEh7/URdWf5tPQVWVuvOewTdVA2NYRXpAAFKhGWp4vD28 brvGPzYgEzBF1Q8p3f9kczbtwqChZuwnwVeP/9EP+U+gApIlmFC8XTISAuBYHWfT baJQJ/V5wjM8m3FmsX4YL8VKplhw2/JMINfD37hzjVlqskN5V80KfNlKTe8yAK96 sP0HDg72zlZ0HHOmOESuxyNyLRYkDpuVNKh4my24u77y/VcpihwMRPc8chnpG76h jh+7qlZZM8XNnVnFJN5HWLiRTUjZ9y3loJ//Wu97JkOr7SuHQ7qzhPDZV/jZepIG XkSD1dac7ii2huA6zxSFZzylwBvLHyrdj4s7imNckkNSbVNpm204Bzs0Rr2ju0bv YBe2+yGkurE8ePfONeaAkpFxHkAkdC0b2SlbZf7MgSaant2s/CV9DGgj03ZipC1g n2juRlDGLw+B1MOU+dWv/cMZmrO3Xg36E0gYgqskYRunqTdVT+Vx70D0rygo7hDd G7qvllT6oqKJ1g== =Eqtp -----END PGP SIGNATURE----- Merge tag 'drm/tegra/for-4.12-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.12-rc1 This contains various fixes to the host1x driver as well as a plug for a leak of kernel pointers to userspace.

Driver core patches for 4.12-rc1
Very tiny pull request for 4.12-rc1 for the driver core this time around. There are some documentation fixes, an eventpoll.h fixup to make it easier for the libc developers to take our header files directly, and some very minor driver core fixes and changes.

USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to the Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task. All of these have been in linux-next for a while with no reported issues.
