2021-01-25drivers: soc: qcom: rpmpd: Add msm8994 RPM Power DomainsKonrad Dybcio1-0/+1
MSM8994 uses similar to MSM8996, legacy-style voltage control, but does not include a VDD_SC_CX line. This setup is also correct for MSM8992. Do note that there exist some boards that use a tertiary PMIC (most likely pm8004), where SMPB on VDDGFX becomes SMPC. I cannot test this configuration though.

2021-01-25bio: don't copy bvec for direct IOPavel Begunkov1-0/+9
The block layer spends quite a while in blkdev_direct_IO() to copy and initialise bio's bvec. However, if we've already got a bvec in the input iterator it might be reused in some cases, i.e. when new ITER_BVEC_FLAG_FIXED flag is set. Simple tests show considerable performance boost, and it also reduces memory footprint.

2021-01-24fs: make helpers idmap mount awareChristian Brauner1-9/+10
Extend some inode methods with an additional user namespace argument. A filesystem that is aware of idmapped mounts will receive the user namespace the mount has been marked with. This can be used for additional permission checking and also to enable filesystems to translate between uids and gids if they need to. We have implemented all relevant helpers in earlier patches. As requested we simply extend the exisiting inode method instead of introducing new ones. This is a little more code churn but it's mostly mechanical and doesnt't leave us with additional inode methods.

2021-01-24acl: handle idmapped mountsChristian Brauner2-3/+6
The posix acl permission checking helpers determine whether a caller is privileged over an inode according to the acls associated with the inode. Add helpers that make it possible to handle acls on idmapped mounts. The vfs and the filesystems targeted by this first iteration make use of posix_acl_fix_xattr_from_user() and posix_acl_fix_xattr_to_user() to translate basic posix access and default permissions such as the ACL_USER and ACL_GROUP type according to the initial user namespace (or the superblock's user namespace) to and from the caller's current user namespace. Adapt these two helpers to handle idmapped mounts whereby we either map from or into the mount's user namespace depending on in which direction we're translating. Similarly, cap_convert_nscap() is used by the vfs to translate user namespace and non-user namespace aware filesystem capabilities from the superblock's user namespace to the caller's user namespace. Enable it to handle idmapped mounts by accounting for the mount's user namespace. In addition the fileystems targeted in the first iteration of this patch series make use of the posix_acl_chmod() and, posix_acl_update_mode() helpers. Both helpers perform permission checks on the target inode. Let them handle idmapped mounts. These two helpers are called when posix acls are set by the respective filesystems to handle this case we extend the ->set() method to take an additional user namespace argument to pass the mount's user namespace down.

2021-01-22mlxsw: Register physical ports as a devlink resourceDanielle Ratson1-0/+14
The switch ASIC has a limited capacity of physical ('flavour physical' in devlink terminology) ports that it can support. While each system is brought up with a different number of ports, this number can be increased via splitting up to the ASIC's limit. Expose physical ports as a devlink resource so that user space will have visibility to the maximum number of ports that can be supported and the current occupancy. In addition, add a "Generic Resources" section in devlink-resource documentation so the different drivers will be aligned by the same resource name when exposing to user space.

2021-01-22scsi: libsas: Introduce a _gfp() variant of event notifiersAhmed S. Darwish1-0/+2
sas_alloc_event() uses in_interrupt() to decide which allocation should be used. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. The in_interrupt() check is also only partially correct, because it fails to choose the correct code path when just preemption or interrupts are disabled. For example, as in the following call chain: mvsas/mv_sas.c: mvs_work_queue() [process context] spin_lock_irqsave(mvs_info::lock, ) -> libsas/sas_event.c: sas_notify_phy_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation -> libsas/sas_event.c: sas_notify_port_event() -> sas_alloc_event() -> in_interrupt() = false -> invalid GFP_KERNEL allocation Introduce sas_alloc_event_gfp(), sas_notify_port_event_gfp(), and sas_notify_phy_event_gfp(), which all behave like the non _gfp() variants but use a caller-passed GFP mask for allocations. For bisectability, all callers will be modified first to pass GFP context, then the non _gfp() libsas API variants will be modified to take a gfp_t by default.

LLDDs report events to libsas with .notify_port_event and .notify_phy_event callbacks. These callbacks are fixed and so there is no reason why the functions cannot be called directly, so do that. This neatens the code slightly, makes it more obvious, and reduces function pointer usage, which is generally a good thing. Downside is that there are 2x more symbol exports.

See below that the links are not accessible any more. $ git clone http://llvm.org/git/llvm.git Cloning into 'llvm'... fatal: unable to access 'http://llvm.org/git/llvm.git/': Maximum (20) redirects followed $ git clone --depth 1 http://llvm.org/git/clang.git Cloning into 'clang'... fatal: unable to access 'http://llvm.org/git/clang.git/': Maximum (20) redirects followed The LLVM community has adopted new ways to build the compiler. There are different ways to build LLVM and Clang, the Clang Getting Started page [1] has one way. As Yonghong said, it is better to copy the build procedure in Documentation/bpf/bpf_devel_QA.rst to keep consistent. I verified the procedure and it is proved to be feasible, so we should update README.rst to reflect the reality. At the same time, update the related comment in Makefile. Additionally, as Fangrui said, the dir llvm-project/llvm/build/install is not used, BUILD_SHARED_LIBS=OFF is the default option [2], so also change Documentation/bpf/bpf_devel_QA.rst together. At last, we recommend that developers who want the fastest incremental builds use the Ninja build system [1], you can find it in your system's package manager, usually the package is ninja or ninja-build [3], so add ninja to build dependencies suggested by Nathan.

Pull device mapper fixes from Mike Snitzer: - Fix DM integrity crash if "recalculate" used without "internal_hash" - Fix DM integrity "recalculate" support to prevent recalculating checksums if we use internal_hash or journal_hash with a key (e.g. HMAC). Use of crypto as a means to prevent malicious corruption requires further changes and was never a design goal for dm-integrity's primary usecase of detecting accidental corruption. - Fix a benign dm-crypt copy-and-paste bug introduced as part of a fix that was merged for 5.11-rc4. - Fix DM core's dm_get_device() to avoid filesystem lookup to get block device (if possible). * tag 'for-5.11/dm-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: avoid filesystem lookup in dm_get_dev_t() dm crypt: fix copy and paste bug in crypt_alloc_req_aead dm integrity: conditionally disable "recalculate" feature dm integrity: fix a crash if "recalculate" used without "internal_hash"

2021-01-22media: dt-bindings: Convert video-interfaces.txt properties to schemasRob Herring3-639/+751
Convert video-interfaces.txt to DT schema. As it contains a mixture of device level and endpoint properties, split it up into 2 schemas. Binding schemas will need to reference both the graph.yaml and video-interfaces.yaml schemas. The exact schema depends on how many ports and endpoints for the binding. A single port with a single endpoint looks similar to this: port: $ref: /schemas/graph.yaml#/$defs/port-base properties: endpoint: $ref: video-interfaces.yaml# unevaluatedProperties: false properties: bus-width: enum: [ 8, 10, 12, 16 ] pclk-sample: true hsync-active: true vsync-active: true required: - bus-width additionalProperties: false Acked-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Jacopo Mondi <jacopo@jmondi.org> Acked-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Rob Herring <robh@kernel.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

2021-01-22net/mlx5: SF, Add auxiliary device supportParav Pandit1-0/+5
Introduce API to add and delete an auxiliary device for an SF. Each SF has its own dedicated window in the PCI BAR 2. SF device is similar to PCI PF and VF that supports multiple class of devices such as net, rdma and vdpa. SF device will be added or removed in subsequent patch during SF devlink port function state change command. A subfunction device exposes user supplied subfunction number which will be further used by systemd/udev to have deterministic name for its netdevice and rdma device.

2021-01-22dt-bindings: display: mxsfb: Add and fix compatible stringsLaurent Pinchart1-5/+13
Additional compatible strings have been added in DT source for the i.MX6SL, i.MX6SLL, i.MX6UL and i.MX7D without updating the bindings. Most of the upstream DT sources use the fsl,imx28-lcdif compatible string, which mostly predates the realization that the LCDIF in the i.MX6 and newer SoCs have extra features compared to the i.MX28. Update the bindings to add the missing compatible strings, with the correct fallback values. This fails to validate some of the upstream DT sources. Instead of adding the incorrect compatible fallback to the binding, the sources should be updated separately.

2021-01-22dt-bindings: display: mxsfb: Convert binding to YAMLLaurent Pinchart2-87/+101
Convert the mxsfb binding to YAML. The deprecated binding is dropped, as neither the DT sources nor the driver support it anymore. The converted binding is named fsl,lcdif.yaml to match the usual bindings naming scheme. The compatible strings are messy, and DT sources use different kinds of combination of documented and undocumented values. Keep it simple for now, and update the example to make it valid. Aligning the binding with the existing DT sources will be performed separately.
