2017-11-18clean up x86 platform driver default valuesLinus Torvalds
The updates this merge window added several bogus default enablement for new features. We don't do that. If people want new behavior, they ask for it. One 'default n' was also removed as pointless. That's great, but there were eight other ones in the same file that were left alone. Fix it up. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.infradead.org/linux-platform-drivers-x86 Pull x86 platform driver updates from Andy Shevchenko: "Here is the collected material against Platform Drivers x86 subsystem. It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver activity For this cycle we have quite an update for the Dell SMBIOS driver including WMI work to provide an interface for SMBIOS tokens via sysfs and WMI support for 2017+ Dell laptop models. SMM dispatcher code is split into a separate driver followed by a new WMI dispatcher. The latter provides a character device interface to user space. The git history also contains a merge of immutable branch from Wolfram Sang in order to apply a dependent fix to the Intel CherryTrail Battery Management driver. Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0 support is added for Intel Skylake. Peaq WMI hotkeys driver gets its own maintainer and white list of supported models. Silead DMI is expanded to support few additional platforms.

2017-11-17Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "We have two changes to the core framework this time around. The first being a large change that introduces runtime PM support to the clk framework. Now we properly call runtime PM operations on the device providing a clk when the clk is in use. This helps on SoCs where the clks provided by a device need something to be powered on before using the clks, like power domains or regulators. It also helps power those things down when clks aren't in use. The other core change is a devm API addition for clk providers so we can get rid of a bunch of clk driver remove functions that are just doing of_clk_del_provider(). Outside of the core, we have the usual addition of clk drivers and smattering of non-critical fixes to existing drivers. The biggest diff is support for Mediatek MT2712 and MT7622 SoCs, but those patches really just add a bunch of data. By the way, we're trying something new here where we build the tree up with topic branches. We plan to work this into our workflow so that we don't step on each other's toes, and so the fixes branch can be merged on an as-needed basis. Summary: Core: - runtime PM support for clk providers - devm API for of_clk_add_hw_provider() New Drivers: - Mediatek MT2712 and MT7622 - Renesas R-Car V3M SoC Updates: - runtime PM support for Samsung exynos5433/exynos4412 providers - removal of clkdev aliases on Samsung SoCs - convert clk-gpio to use gpio descriptors - various driver cleanups to match kernel coding style - Amlogic Video Processing Unit VPU and VAPB clks - sigma-delta modulation for Allwinner audio PLLs - Allwinner A83t Display clks - support for the second display unit clock on Renesas RZ/G1E - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR - new clock ids for Rockchip rk3188 and rk3368 SoCs - various 'const' markings on clk_ops structures - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs" * tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: (137 commits) clk: stm32h7: fix test of clock config clk: pxa: fix building on older compilers clk: sunxi-ng: a83t: Fix i2c buses bits clk: ti: dra7-atl-clock: fix child-node lookups clk: qcom: common: fix legacy board-clock registration clk: uniphier: fix DAPLL2 clock rate of Pro5 clk: uniphier: fix parent of miodmac clock data clk: hi3798cv200: correct parent mux clock for 'clk_sdio0_ciu' clk: hisilicon: Delete an error message for a failed memory allocation in hisi_register_clkgate_sep() clk: hi3660: fix incorrect uart3 clock freqency clk: kona-setup: Delete error messages for failed memory allocations ARC: clk: fix spelling mistake: "configurarion" -> "configuration" clk: cdce925: remove redundant check for non-null parent_name clk: versatile: Improve sizeof() usage clk: versatile: Delete error messages for failed memory allocations clk: ux500: Improve sizeof() usage clk: ux500: Delete error messages for failed memory allocations clk: spear: Delete error messages for failed memory allocations clk: ti: Delete error messages for failed memory allocations clk: mmp: Adjust checks for NULL pointers ...

2017-11-18ipvlan: NULL pointer dereference panic in ipvlan_port_destroyGirish Moodalbail
When call to register_netdevice() (called from ipvlan_link_new()) fails, we call ipvlan_uninit() (through ndo_uninit()) to destroy the ipvlan port. After returning unsuccessfully from register_netdevice() we go ahead and call ipvlan_port_destroy() again which causes NULL pointer dereference panic. Fix the issue by making ipvlan_init() and ipvlan_uninit() call symmetric. The ipvlan port will now be created inside ipvlan_init() and will be destroyed in ipvlan_uninit().

Pull amdgpu DC display code for Vega from Dave Airlie: "This is the pull request for the AMD DC (display code) layer which is a requirement to program the display engines on the new Vega and Raven based GPUs. It also contains support for all amdgpu supported GPUs (CIK, VI, Polaris), which has to be enabled. It is also a kms atomic modesetting compatible driver (unlike the current in-tree display code). I've kept it separate from drm-next because it may have some things that cause you to reject it. Background story: AMD have an internal team creating a shared OS codebase for display at hw bring up time using information from their hardware teams. This process doesn't lead to the most Linux friendly/looking code but we have worked together on cleaning a lot of it up and dealing with sparse/smatch/checkpatch, and having their team internally adhere to Linux coding standards. This tree is a complete history rebased since they started opening it, we decided not to squash it down as the history may have some value. Some of the commits therefore might not reach kernel standards, and we are steadily training people in AMD to better write commit msgs. There is a major bunch of generated bandwidth calculation and verification code that comes from their hardware team. On Vega and before this is float calculations, on Raven (DCN10) this is double based. They do the required things to do FP in the kernel, and I could understand this might raise some issues. Rewriting the bandwidth would be a major undertaken in reverification, it's non-trivial to work out if a display can handle the complete set of mode information thrown at it. Future story: There is a TODO list with this, and it address most of the remaining things that would be nice to refine/remove. The DCN10 code is still under development internally and they push out a lot of patches quite regularly and are supporting this code base with their display team. I think we've reached the point where keeping it out of tree is going to motivate distributions to start carrying the code, so I'd prefer we get it in tree. I think this code is slightly better than STAGING quality but not massively so, I'd really like to see that float/double magic gone and fixed point used, but AMD don't seem to think the accuracy and revalidation of the code is worth the effort" * tag 'drm-for-v4.15-amd-dc' of git://people.freedesktop.org/~airlied/linux: (1110 commits) drm/amd/display: fix MST link training fail division by 0 drm/amd/display: Fix formatting for null pointer dereference fix drm/amd/display: Remove dangling planes on dc commit state drm/amd/display: add flip_immediate to commit update for stream drm/amd/display: Miss register MST encoder cbs drm/amd/display: Fix warnings on S3 resume drm/amd/display: use num_timing_generator instead of pipe_count drm/amd/display: use configurable FBC option in dm drm/amd/display: fix AZ clock not enabled before program AZ endpoint amdgpu/dm: Don't use DRM_ERROR in amdgpu_dm_atomic_check amd/display: Fix potential null dereference in dce_calcs.c amdgpu/dm: Remove unused forward declaration drm/amdgpu: Remove unused dc_stream from amdgpu_crtc amdgpu/dc: Fix double unlock in amdgpu_dm_commit_planes amdgpu/dc: Fix missing null checks in amdgpu_dm.c amdgpu/dc: Fix potential null dereferences in amdgpu_dm.c amdgpu/dc: fix more indentation warnings amdgpu/dc: handle allocation failures in dc_commit_planes_to_stream. amdgpu/dc: fix indentation warning from smatch. amdgpu/dc: fix non-ansi function decls. ...

The ext4 touches came from Jan, and the xfs touches have Darrick's reviewed-by. An xfstest for the MAP_SYNC feature has been through a few round of reviews and is on track to be merged. - 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.

2017-11-16platform/x86: dell-*wmi*: Relay failed initial probe to dependent driversMario Limonciello
dell-wmi and dell-smbios-wmi are dependent upon dell-wmi-descriptor finishing probe successfully to probe themselves. Currently if dell-wmi-descriptor fails probing in a non-recoverable way (such as invalid header) dell-wmi and dell-smbios-wmi will continue to try to redo probing due to deferred probing. To solve this have the dependent drivers query the dell-wmi-descriptor driver whether the descriptor has been determined valid. The possible results are: -ENODEV: Descriptor GUID missing from WMI bus -EPROBE_DEFER: Descriptor not yet probed, dependent driver should wait and use deferred probing < 0: Descriptor probed, invalid. Dependent driver should return an error. 0: Successful descriptor probe, dependent driver can continue Successful descriptor probe still doesn't mean that the descriptor driver is necessarily bound at the time of initialization of dependent driver. Userspace can unbind the driver, so all methods used from driver should still be verified to return success values otherwise deferred probing be used.

2017-11-16PM / runtime: Drop children check from __pm_runtime_set_status()Rafael J. Wysocki
The check for "active" children in __pm_runtime_set_status(), when trying to set the parent device status to "suspended", doesn't really make sense, because in fact it is not invalid to set the status of a device with runtime PM disabled to "suspended" in any case. It is invalid to enable runtime PM for a device with its status set to "suspended" while its child_count reference counter is nonzero, but the check in __pm_runtime_set_status() doesn't really cover that situation. For this reason, drop the children check from __pm_runtime_set_status() and add a check against child_count reference counters of "suspended" devices to pm_runtime_enable().

2017-11-16dm bufio: fix integer overflow when limiting maximum cache sizeEric Biggers
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.

2017-11-16dm: clear all discard attributes in queue_limits when discards are disabledMike Snitzer
Otherwise, it can happen that the QUEUE_FLAG_DISCARD isn't set but the various discard attributes (which get exposed via sysfs) may be set. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2017-11-16dm: do not set 'discards_supported' in targets that do not need itMike Snitzer
The DM target's 'discards_supported' flag is intended to act as an override. Meaning, even if the underlying storage doesn't support discards the DM target will. Signed-off-by: Mike Snitzer <snitzer@redhat.com>
2017-11-16dm: discard support requires all targets in a table support discardsMike Snitzer
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.
