sh/boot: add static stack-protector to pre-kernel
The sh decompressor code triggers stack-protector code generation when using CONFIG_CC_STACKPROTECTOR_STRONG. As done for arm and mips, add a simple static stack-protector canary. As this wasn't protected before, the risk of using a weak canary is minimized. Once the kernel is actually up, a better canary is chosen.

proc, coredump: add CoreDumping flag to /proc/pid/status
Right now there is no convenient way to check if a process is being coredumped at the moment. It might be necessary to recognize such state to prevent killing the process and getting a broken coredump. Writing a large core might take significant time, and the process is unresponsive during it, so it might be killed by timeout, if another process is monitoring and killing/restarting hanging tasks. We're getting a significant number of corrupted coredump files on machines in our fleet, just because processes are being killed by timeout in the middle of the core writing process. We do have a process health check, and some agent is responsible for restarting processes which are not responding for health check requests. Writing a large coredump to the disk can easily exceed the reasonable timeout (especially on an overloaded machine). This flag will allow the agent to distinguish processes which are being coredumped, extend the timeout for them, and let them produce a full coredump file. To provide an ability to detect if a process is in the state of being coredumped, we can expose a boolean CoreDumping flag in /proc/pid/status. Example: $ cat core.sh #!/bin/sh echo "|/usr/bin/sleep 10" > /proc/sys/kernel/core_pattern sleep 1000 & PID=$! cat /proc/$PID/status | grep CoreDumping kill -ABRT $PID sleep 1 cat /proc/$PID/status | grep CoreDumping $ ./core.sh CoreDumping: 0 CoreDumping: 1 [guro@fb.com: document CoreDumping flag in /proc/<pid>/status] Link: http://lkml.kernel.org/r/20170928135357.GA8470@castle.DHCP.thefacebook.com Link: http://lkml.kernel.org/r/20170920230634.31572-1-guro@fb.com Signed-off-by: Roman Gushchin <guro@fb.com> Cc: Alexander Viro <viro@zeniv.linux.org.uk> Cc: Ingo Molnar <mingo@kernel.org> Cc: Konstantin Khlebnikov <koct9i@gmail.com> Cc: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

mm, compaction: remove unneeded pageblock_skip_persistent() checks
Commit f3c931633a59 ("mm, compaction: persistently skip hugetlbfs pageblocks") has introduced pageblock_skip_persistent() checks into migration and free scanners, to make sure pageblocks that should be persistently skipped are marked as such, regardless of the ignore_skip_hint flag. Since the previous patch introduced a new no_set_skip_hint flag, the ignore flag no longer prevents marking pageblocks as skipped. Therefore we can remove the special cases. The relevant pageblocks will be marked as skipped by the common logic which marks each pageblock where no page could be isolated. This makes the code simpler.

mm, compaction: extend pageblock_skip_persistent() to all compound pages
pageblock_skip_persistent() checks for HugeTLB pages of pageblock order. When clearing pageblock skip bits for compaction, the bits are not cleared for such pageblocks, because they cannot contain base pages suitable for migration, nor free pages to use as migration targets. This optimization can be simply extended to all compound pages of order equal or larger than pageblock order, because migrating such pages (if they support it) cannot help sub-pageblock fragmentation. This includes THP's and also gigantic HugeTLB pages, which the current implementation doesn't persistently skip due to a strict pageblock_order equality check and not recognizing tail pages. While THP pages are generally less "persistent" than HugeTLB, we can still expect that if a THP exists at the point of __reset_isolation_suitable(), it will exist also during the subsequent compaction run. The time difference here could be actually smaller than between a compaction run that sets a (non-persistent) skip bit on a THP, and the next compaction run that observes it.

mm, compaction: persistently skip hugetlbfs pageblocks
It is pointless to migrate hugetlb memory as part of memory compaction if the hugetlb size is equal to the pageblock order. No defragmentation is occurring in this condition. It is also pointless to for the freeing scanner to scan a pageblock where a hugetlb page is pinned. Unconditionally skip these pageblocks, and do so peristently so that they are not rescanned until it is observed that these hugepages are no longer pinned. It would also be possible to do this by involving the hugetlb subsystem in marking pageblocks to no longer be skipped when they hugetlb pages are freed. This is a simple solution that doesn't involve any additional subsystems in pageblock skip manipulation.

mm, compaction: kcompactd should not ignore pageblock skip
Kcompactd is needlessly ignoring pageblock skip information. It is doing MIGRATE_SYNC_LIGHT compaction, which is no more powerful than MIGRATE_SYNC compaction. If compaction recently failed to isolate memory from a set of pageblocks, there is nothing to indicate that kcompactd will be able to do so, or that it is beneficial from attempting to isolate memory. Use the pageblock skip hint to avoid rescanning pageblocks needlessly until that information is reset.

mm/z3fold.c: use kref to prevent page free/compact race
There is a race in the current z3fold implementation between do_compact() called in a work queue context and the page release procedure when page's kref goes to 0. do_compact() may be waiting for page lock, which is released by release_z3fold_page_locked right before putting the page onto the "stale" list, and then the page may be freed as do_compact() modifies its contents. The mechanism currently implemented to handle that (checking the PAGE_STALE flag) is not reliable enough. Instead, we'll use page's kref counter to guarantee that the page is not released if its compaction is scheduled. It then becomes compaction function's responsibility to decrease the counter and quit immediately if the page was actually freed.

mm: fix nodemask printing

./include/linux/nodemask.h:108:11: warning: the comparison will always evaluate as `true' for the address of `nodes' will never be NULL [-Waddress]
An earlier workaround I suggested was incorporated in the version that
got merged, but that only solved the problem for gcc-7 and higher, while
gcc-4.6 through gcc-6.x still warn.
This changes the printing again to use inline functions that make it
clear to the compiler that the line that does the NULL check has no idea
whether the argument is a constant NULL.

libnvdimm for 4.15
* Introduce MAP_SYNC and MAP_SHARED_VALIDATE, a mechanism to enable 'userspace flush' of persistent memory updates via filesystem-dax mappings. It arranges for any filesystem metadata updates that may be required to satisfy a write fault to also be flushed ("on disk") before the kernel returns to userspace from the fault handler. Effectively every write-fault that dirties metadata completes an fsync() before returning from the fault handler. The new MAP_SHARED_VALIDATE mapping type guarantees that the MAP_SYNC flag is validated as supported by the filesystem's ->mmap() file operation. * Add support for the standard ACPI 6.2 label access methods that replace the NVDIMM_FAMILY_INTEL (vendor specific) label methods. This enables interoperability with environments that only implement the standardized methods. * Add support for the ACPI 6.2 NVDIMM media error injection methods. * Add support for the NVDIMM_FAMILY_INTEL v1.6 DIMM commands for latch last shutdown status, firmware update, SMART error injection, and SMART alarm threshold control. * Cleanup physical address information disclosures to be root-only. * Fix revalidation of the DIMM "locked label area" status to support dynamic unlock of the label area. * Expand unit test infrastructure to mock the ACPI 6.2 Translate SPA (system-physical-address) command and error injection commands.

As usual, lots of new boards get added based on those and other SoCs: - Actions S500 based CubieBoard6 single-board computer - Amlogic Meson-AXG A113D based development board - Amlogic S912 based Khadas VIM2 single-board computer - Amlogic S912 based Tronsmart Vega S96 set-top-box - Allwinner H5 based NanoPi NEO Plus2 single-board computer - Allwinner R40 based Banana Pi M2 Ultra and Berry single-board computers - Allwinner A83T based TBS A711 Tablet - Broadcom Hurricane 2 based Ubiquiti UniFi Switch 8 - Broadcom bcm47xx based Luxul XAP-1440/XAP-810/ABR-4500/XBR-4500 wireless access points and routers - NXP i.MX51 based Zodiac Inflight Innovations RDU1 board - NXP i.MX53 based GE Healthcare PPD biometric monitor - NXP i.MX6 based Pistachio single-board computer - NXP i.MX6 based Vining-2000 automotive diagnostic interface - NXP i.MX6 based Ka-Ro TX6 Computer-on-Module in additional variants - Qualcomm MSM8974 (Snapdragon 800) based Fairphone 2 phone - Qualcomm MSM8974pro (Snapdragon 801) based Sony Xperia Z2 Tablet - Realtek RTD1295 based set-top-boxes MeLE V9 and PROBOX2 AVA - Renesas R-Car V3M (R8A77970) SoC and "Eagle" reference board - Renesas H3ULCB and M3ULCB "Kingfisher" extension infotainment boards - Renasas r8a7745 based iWave G22D-SODIMM SoM - Rockchip rk3288 based Amarula Vyasa single-board computer - Samsung Exynos5800 based Odroid HC1 single-board computer For existing SoC support, there was a lot of ongoing work, as usual most of that concentrated on the Renesas, Rockchip, OMAP, i.MX, Amlogic and Allwinner platforms, but others were also active. Rob Herring and many others worked on reducing the number of issues that the latest version of 'dtc' now warns about. Unfortunately there is still a lot left to do.

ARM: SoC platform updates for 4.15
Most of the commits are for defconfig changes, to enable newly added drivers or features that people have started using. For the changed lines lines, we have mostly cleanups, the affected platforms are OMAP, Versatile, EP93xx, Samsung, Broadcom, i.MX, and Actions. The largest single change is the introduction of the TI "sysc" bus driver, with the intention of cleaning up more legacy code. Two new SoC platforms get added this time: - Allwinner R40 is a modernized version of the A20 chip, now with a Quad-Core ARM Cortex-A7. According to the manufacturer, it is intended for "Smart Hardware" - Broadcom Hurricane 2 (Aka Strataconnect BCM5334X) is a family of chips meant for managed gigabit ethernet switches, based around a Cortex-A9 CPU. Finally, we gain SMP support for two platforms: Renesas R-Car E2 and Amlogic Meson8/8b, which were previously added but only supported uniprocessor operation. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaDgf/AAoJEGCrR//JCVIntcMQAKI2q0Dr2giWtKSoH9GDh5co 137MamTj1YExIcmtbDVO22jV4WSKhIduo+rRBYmQ/uvrkUe9tf7I172JeAIzMzGf HGYJ6fxpaEMUAbUlNcjuXJc7jQXNKLBK2X9CMuwXX3X3HddxKkL38D1d/Mxv5RGu G1pEe0j734Qio9LpACnb0xnluwyUBJOYNwo7Agj5RWzOrXZ+TdwkiIW0JdQiG7Z5 wabzDa7OW1maB+hVYMAM3wHcqO7DKEvGvjYLRoT12cnOLXq7BNbXqXFufuMUNmNE ABhWA1h9SYrXT3n5pQLwoonvvTsI7KXCefrZ0wuxbjrdD4yGW1gmgpRee9RfoggD A6/62wpmSS61X5QWC6BLEa5v/o5NKewndyWhnjLllgJX8sRUbnPQa/xKv7ngdlN5 7YL5HWoNpMQv7fEweSc6j5l/F3yRBndn9TpeKiqCiUiNDrIGlZYhYKIcr9rGESFk pu2KgK+e9+1k7F4s7LotsA65Q5bZIMveyyVtx0XHXz1G4O8NksoQCLJ3wcqQ2pzI WpyOO5R1CNltPhKGC7EP3OZcIMlCtCnsNcedb/AGHgPS+ert2UxBnlSeSMBQlLZY 4fDwEAlA1qx9PuG9N3xrK/gAFiFLafK2sNxtVc7NSmXkkdm3xgJ95Y9sa72Y2qNO rU2LL8SM7cOwhXHrlEFB =jlJ2 -----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: "Most of the commits are for defconfig changes, to enable newly added drivers or features that people have started using.

dm bufio: fix integer overflow when limiting maximum cache size
The default max_cache_size_bytes for dm-bufio is meant to be the lesser of 25% of the size of the vmalloc area and 2% of the size of lowmem. However, on 32-bit systems the intermediate result in the expression (VMALLOC_END - VMALLOC_START) * DM_BUFIO_VMALLOC_PERCENT / 100 overflows, causing the wrong result to be computed. For example, on a 32-bit system where the vmalloc area is 520093696 bytes, the result is 1174405 rather than the expected 130023424, which makes the maximum cache size much too small (far less than 2% of lowmem). This causes severe performance problems for dm-verity users on affected systems. Fix this by using mult_frac() to correctly multiply by a percentage. Do this for all places in dm-bufio that multiply by a percentage. Also replace (VMALLOC_END - VMALLOC_START) with VMALLOC_TOTAL, which contrary to the comment is now defined in include/linux/vmalloc.h. Depends-on: |

dm: do not set 'discards_supported' in targets that do not need it

dm: discard support requires all targets in a table support discards
A DM device with a mix of discard capabilities (due to some underlying devices not having discard support) _should_ just return -EOPNOTSUPP for the region of the device that doesn't support discards (even if only by way of the underlying driver formally not supporting discards). BUT, that does ask the underlying driver to handle something that it never advertised support for. In doing so we're exposing users to the potential for a underlying disk driver hanging if/when a discard is issued a the device that is incapable and never claimed to support discards. Fix this by requiring that each DM target in a DM table provide discard support as a prereq for a DM device to advertise support for discards. This may cause some configurations that were happily supporting discards (even in the face of a mix of discard support) to stop supporting discards -- but the risk of users hitting driver hangs, and forced reboots, outweighs supporting those fringe mixed discard configurations.

dm mpath: remove annoying message of 'blk_get_request() returned -11'
It is very normal to see allocation failure, especially with blk-mq request_queues, so it's unnecessary to report this error and annoy people. In practice this 'blk_get_request() returned -11' error gets logged quite frequently when a blk-mq DM multipath device sees heavy IO. This change is marked for stable@ because the annoying message in question was included in stable@ commit |

Highlights: - Support for a new OPAL call on bare metal machines which gives us a true NMI (ie. is not masked by MSR[EE]=0) for debugging etc. - Support for Power9 DD2 in the CXL driver. - Improvements to machine check handling so that uncorrectable errors can be reported into the generic memory_failure() machinery. - Some fixes and improvements for VPHN, which is used under PowerVM to notify the Linux partition of topology changes. - Plumbing to enable TM (transactional memory) without suspend on some Power9 processors (PPC_FEATURE2_HTM_NO_SUSPEND). - Support for emulating vector loads form cache-inhibited memory, on some Power9 revisions. - Disable the fast-endian switch "syscall" by default (behind a CONFIG), we believe it has never had any users. - A major rework of the API drivers use when initiating and waiting for long running operations performed by OPAL firmware, and changes to the powernv_flash driver to use the new API. - Several fixes for the handling of FP/VMX/VSX while processes are using transactional memory. - Optimisations of TLB range flushes when using the radix MMU on Power9. - Improvements to the VAS facility used to access coprocessors on Power9, and related improvements to the way the NX crypto driver handles requests. - Implementation of PMEM_API and UACCESS_FLUSHCACHE for 64-bit.

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull user namespace update from Eric Biederman: "The only change that is production ready this round is the work to increase the number of uid and gid mappings a user namespace can support from 5 to 340. This code was carefully benchmarked and it was confirmed that in the existing cases the performance remains the same. In the worst case with 340 mappings an cache cold stat times go from 158ns to 248ns. That is noticable but still quite small, and only the people who are doing crazy things pay the cost. This work uncovered some documentation and cleanup opportunities in the mapping code, and patches to make those cleanups and improve the documentation will be coming in the next merge window" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: userns: Simplify insert_extent userns: Make map_id_down a wrapper for map_id_range_down userns: Don't read extents twice in m_start userns: Simplify the user and group mapping functions userns: Don't special case a count of 0 userns: bump idmap limits to 340 userns: use union in {g,u}idmap struct |

f2fs-for-4.15-rc1
In this round, we introduce sysfile-based quota support which is required for Android by default. In addition, we allow that users are able to reserve some blocks in runtime to mitigate performance drops in low free space. Enhancement - assign proper data segments according to write_hints given by user - issue cache_flush on dirty devices only among multiple devices - exploit cp_error flag and add more faults to enhance fault injection test - conduct more readaheads during f2fs_readdir - add a range for discard commands Bug fix - fix zero stat->st_blocks when inline_data is set - drop crypto key and free stale memory pointer while evict_inode is failing - fix some corner cases in free space and segment management - fix wrong last_disk_size This series includes lots of clean-ups and code enhancement in terms of xattr operations, discard/flush command control. In addition, it adds versatile debugfs entries to monitor f2fs status. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAloNCPAACgkQQBSofoJI UNLYmg/8DbDp/mTXqJ0AURo84Z4OQUOTRxYkWazx4ct2WPZp2+5HCWDDoM8AAtUn 1J6/t7cU3osjos+zWvpUREZq1SPbp5m0h818HBFFJ/YMBPXucdQcd6wpepniOR5J 5uKauVd7jd2pbAAL7hKyr+iBSLrJl816wsq34Ml8y8zkDSJe4wO5YsGDqzqyKf4N 8nxMavUgerb14I/qXPb3ljlYlfaNNRlCT649QGCG78gx5hPeiUtUJ2l5DKV2xPe7 v+5lZO93FFwW1siGy+Atq+nqQJyUkeiOYGPR1NPx9tfmaPO58iOIXLirfblKASZY HXJigVf50fQQBtwdBFL8ICSop6zV6gCKkNGZCHLzcYFWWL2TQwCIP3/iJdj9Wy+j +YUYyN0dyl2mmNEDZjRNX1V+QBW1k+msmvBCb0fT1GJTQAyRfA4XfBDyg94cpWQ1 9YivNywuzG8YtghY7gYU3lCfT2OG19nXCSdz4qYUb5SSwoeGtLahLxMV4mlil4Tg dOa8CPLFhJnCqB9ivI4L6SennBr+gNgL26SeZ3PF+B5KimYOTZxbenrll1kTi1xp uCU6UR1xJS0W7Cjk8sCIu5hXkJMJwPJ0hcVeTgsxMkujLGvSSRCGb2hmOeILfwRZ N4aGn+kVmwwgKaKjD/F4CY4b3yJLdTKMjjl74u5YaMQWe4Bq4qU= =c49T -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we introduce sysfile-based quota support which is required for Android by default.

The major points of the overhaul are: (1) Preliminary groundwork is laid for supporting network-namespacing of kAFS. The remainder of the namespacing work requires some way to pass namespace information to submounts triggered by an automount. This requires something like the mount overhaul that's in progress. (2) sockaddr_rxrpc is used in preference to in_addr for holding addresses internally and add support for talking to the YFS VL server. With this, kAFS can do everything over IPv6 as well as IPv4 if it's talking to servers that support it. (3) Callback handling is overhauled to be generally passive rather than active. 'Callbacks' are promises by the server to tell us about data and metadata changes. Callbacks are now checked when we next touch an inode rather than actively going and looking for it where possible. (4) File access permit caching is overhauled to store the caching information per-inode rather than per-directory, shared over subordinate files. Whilst older AFS servers only allow ACLs on directories (shared to the files in that directory), newer AFS servers break that restriction. To improve memory usage and to make it easier to do mass-key removal, permit combinations are cached and shared. (5) Cell database management is overhauled to allow lighter locks to be used and to make cell records autonomous state machines that look after getting their own DNS records and cleaning themselves up, in particular preventing races in acquiring and relinquishing the fscache token for the cell. (6) Volume caching is overhauled. The afs_vlocation record is got rid of to simplify things and the superblock is now keyed on the cell and the numeric volume ID only. The volume record is tied to a superblock and normal superblock management is used to mediate the lifetime of the volume fscache token. (7) File server record caching is overhauled to make server records independent of cells and volumes. A server can be in multiple cells (in such a case, the administrator must make sure that the VL services for all cells correctly reflect the volumes shared between those cells). Server records are now indexed using the UUID of the server rather than the address since a server can have multiple addresses. (8) File server rotation is overhauled to handle VMOVED, VBUSY (and similar), VOFFLINE and VNOVOL indications and to handle rotation both of servers and addresses of those servers. The rotation will also wait and retry if the server says it is busy. (9) Data writeback is overhauled. Each inode no longer stores a list of modified sections tagged with the key that authorised it in favour of noting the modified region of a page in page->private and storing a list of keys that made modifications in the inode. This simplifies things and allows other keys to be used to actually write to the server if a key that made a modification becomes useless. (10) Writable mmap() is implemented. This allows a kernel to be build entirely on AFS. Note that Pre AFS-3.4 servers are no longer supported, though this can be added back if necessary (AFS-3.4 was released in 1998)" * tag 'afs-next-20171113' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (35 commits) afs: Protect call->state changes against signals afs: Trace page dirty/clean afs: Implement shared-writeable mmap afs: Get rid of the afs_writeback record afs: Introduce a file-private data record afs: Use a dynamic port if 7001 is in use afs: Fix directory read/modify race afs: Trace the sending of pages afs: Trace the initiation and completion of client calls afs: Fix documentation on # vs % prefix in mount source specification afs: Fix total-length calculation for multiple-page send afs: Only progress call state at end of Tx phase from rxrpc callback afs: Make use of the YFS service upgrade to fully support IPv6 afs: Overhaul volume and server record caching and fileserver rotation afs: Move server rotation code into its own file afs: Add an address list concept afs: Overhaul cell database management afs: Overhaul permit caching afs: Overhaul the callback handling afs: Rename struct afs_call server member to cm_server ... |

This is the bulk of pin control changes for the v4.15
kernel cycle: Core: - The pin control Kconfig entry PINCTRL is now turned into a menuconfig option. This obviously has the implication of making the subsystem menu visible in menuconfig. This is happening because of two things: - Intel have started to deploy and depend on pin controllers in a way that is affecting users directly. This happens on the highly integrated laptop chipsets named after geographical places: baytrail, broxton, cannonlake, cedarfork, cherryview, denverton, geminilake, lewisburg, merrifield, sunrisepoint... It started a while back and now it is ever more evident that this is crucial infrastructure for x86 laptops and not an embedded obscurity anymore. Users need to be aware. - Pin control expanders on I2C and SPI that are arch-agnostic. Currently Semtech SX150X and Microchip MCP28x08 but more are expected. Users will have to be able to configure these in directly for their set-up. - Just go and select GPIOLIB now that we made sure that GPIOLIB is a very vanilla subsystem. Do not depend on it, if we need it, select it. - Exposing the pin control subsystem in menuconfig uncovered a bunch of obscure bugs that are now hopefully fixed, all more or less pertaining to Blackfin. - Unified namespace for cross-calls between pin control and GPIO. - New support for clock skew/delay generic DT bindings and generic pin config options for this. - Minor documentation improvements. Various: - The Renesas SH-PFC pin controller has evolved a lot. It seems Renesas are churning out new SoCs by the minute. - A bunch of non-critical fixes for the Rockchip driver. - Improve the use of library functions instead of open coding. - Support the MCP28018 variant in the MCP28x08 driver. - Static constifying. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJaDV9TAAoJEEEQszewGV1zf0AQAIlHxM8B0mJPOFv7WdPIHs8j GSGAPv0rPobdgZI8vegosIQmAiry5jjaHP6VGOrK5n8FRxfBLd89NLT7dgK7J9Yx tYcQRQn1/MqZKaIjWWgTes3okEr9s77Of3aWkA9gyvBjTGoo2hu8BTwZOYuPrIPP aYcI7VR0VbTe7FQR1QRtKBXnBTXfznF1j5ckKNY4ahgIPcUgxyh6EA1E61rDorLK gvwwzoBqIKQAcnapgarF7YOJjoE0i7ZoSlhL0b0nvhcgolyK/zLN4xujLcTGPeTJ hQwe7LhxtvtmJmu0jRMuetDLFT52d6eq8ttyFBMULkgRzcgMv6GZZXUy4k92t7ZT F2DRbAjyAlxkhUhQ8BORzEXwfWYITt1M49jWQqugdDR2fV/MAlF8motOkVBl73iS zHIQ/ZDcAD+PlwTHiDyDOUxj7qyDs2MkTLTzfXc0koOQZOqskDHQ1dIf3UzLzZ9S /dx339/ejwP73E0lzOsanhianfonqWZ3Apn3aRG18uqCt2+eHySWpxyRANuOlBZI czERg+47wDfng24xyuH0EElgbS5G0Bt1lT5zLVLdFEvoLmcBHVKqaCkiuvYXOjVM GyMRvQPiJbhT6qiJ+aSP8t/utl1aUhXQLtrUnXxu8qv9tQ6jgmqiQd9855Uvrzb0 ZR2wyNc2jtWzwCfrkWjt =kj/b -----END PGP SIGNATURE----- Merge tag 'pinctrl-v4.15-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control updates from Linus Walleij: "This is the bulk of pin control changes for the v4.15 kernel cycle: Core: - The pin control Kconfig entry PINCTRL is now turned into a menuconfig option.

Char/Misc patches for 4.15-rc1
Here is the big set of char/misc and other driver subsystem patches for 4.15-rc1. There are small changes all over here, hyperv driver updates, pcmcia driver updates, w1 driver updats, vme driver updates, nvmem driver updates, and lots of other little one-off driver updates as well. The shortlog has the full details. Note, there will be a merge conflict in drivers/misc/lkdtm_core.c when merging to your tree as one lkdtm patch came in through the perf tree as well as this one. The resolution is to take the const change that this tree provides. All of these have been in linux-next for quite a while with no reported issues.

mm: make alloc_node_mem_map a void call if we don't have CONFIG_FLAT_NODE_MEM_MAP
free_area_init_node() calls alloc_node_mem_map(), but this function does nothing unless we have CONFIG_FLAT_NODE_MEM_MAP. As a cleanup, we can move the "#ifdef CONFIG_FLAT_NODE_MEM_MAP" within alloc_node_mem_map() out of the function, and define a alloc_node_mem_map() { } when CONFIG_FLAT_NODE_MEM_MAP is not present. This also moves the printk that lays within the "#ifdef CONFIG_FLAT_NODE_MEM_MAP" block from free_area_init_node() to alloc_node_mem_map(), getting rid of the "#ifdef CONFIG_FLAT_NODE_MEM_MAP" in free_area_init_node().

mm: simplify nodemask printing
alloc_warn() and dump_header() have to explicitly handle NULL nodemask which forces both paths to use pr_cont. We can do better. printk already handles NULL pointers properly so all we need is to teach nodemask_pr_args to handle NULL nodemask carefully. This allows simplification of both alloc_warn() and dump_header() and gets rid of pr_cont altogether. This patch has been motivated by patch from Joe Perches http://lkml.kernel.org/r/b31236dfe3fc924054fd7842bde678e71d193638.1509991345.git.joe@perches.com [akpm@linux-foundation.org: fix tile warning, per Arnd] Link: http://lkml.kernel.org/r/20171109100531.3cn2hcqnuj7mjaju@dhcp22.suse.cz Signed-off-by: Michal Hocko <mhocko@suse.com> Acked-by: Joe Perches <joe@perches.com> Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

mm,oom_reaper: remove pointless kthread_run() error check
Since oom_init() is called before userspace processes start, memory allocation failure for creating the OOM reaper kernel thread will let the OOM killer call panic() rather than wake up the OOM reaper.

mm/page_ext.c: check if page_ext is not prepared
online_page_ext() and page_ext_init() allocate page_ext for each section, but they do not allocate if the first PFN is !pfn_present(pfn) or !pfn_valid(pfn). Then section->page_ext remains as NULL. lookup_page_ext checks NULL only if CONFIG_DEBUG_VM is enabled. For a valid PFN, __set_page_owner will try to get page_ext through lookup_page_ext. Without CONFIG_DEBUG_VM lookup_page_ext will misuse NULL pointer as value 0. This incurrs invalid address access. This is the panic example when PFN 0x100000 is not valid but PFN 0x13FC00 is being used for page_ext. section->page_ext is NULL, get_entry returned invalid page_ext address as 0x1DFA000 for a PFN 0x13FC00. To avoid this panic, CONFIG_DEBUG_VM should be removed so that page_ext will be checked at all times.
