2018-05-31arm64: Call ARCH_WORKAROUND_2 on transitions between EL0 and EL1Marc Zyngier
In order for the kernel to protect itself, let's call the SSBD mitigation implemented by the higher exception level (either hypervisor or firmware) on each transition between userspace and kernel. We must take the PSCI conduit into account in order to target the right exception level, hence the introduction of a runtime patching callback.

2018-05-31arm/arm64: smccc: Add SMCCC-specific return codesMarc Zyngier
We've so far used the PSCI return codes for SMCCC because they were extremely similar. But with the new ARM DEN 0070A specification, "NOT_REQUIRED" (-2) is clashing with PSCI's "PSCI_RET_INVALID_PARAMS". Let's bite the bullet and add SMCCC specific return codes. Users can be repainted as and when required.

2018-05-31dax: change bdev_dax_supported() to support boolean returnsDave Jiang
The function return values are confusing with the way the function is named. We expect a true or false return value but it actually returns 0/-errno. This makes the code very confusing. Changing the return values to return a bool where if DAX is supported then return true and no DAX support returns false.

2018-05-31fs: allow per-device dax status checking for filesystemsDarrick J. Wong
Change bdev_dax_supported so it takes a bdev parameter. This enables multi-device filesystems like xfs to check that a dax device can work for the particular filesystem. Once that's in place, actually fix all the parts of XFS where we need to be able to distinguish between datadev and rtdev. This patch fixes the problem where we screw up the dax support checking in xfs if the datadev and rtdev have different dax capabilities. Signed-off-by: Darrick J.

2018-05-31usb: hub: Per-port setting to reduce TRSTRCY to 10 msNicolas Boichat
Currently, the USB hub core waits for 50 ms after enumerating the device. This was added to help "some high speed devices" to enumerate (b789696af8 "[PATCH] USB: relax usbcore reset timings"). On some devices, the time-to-active is important, so we provide a per-port option to reduce the time to what the USB specification requires: 10 ms.

2018-05-31usb: hub: Per-port setting to use old enumeration schemeNicolas Boichat
The "old" enumeration scheme is considerably faster (it takes ~244ms instead of ~356ms to get the descriptor). It is currently only possible to use the old scheme globally (/sys/module/usbcore/parameters/old_scheme_first), which is not desirable as the new scheme was introduced to increase compatibility with more devices. However, in our case, we care about time-to-active for a specific USB device (which we make the firmware for), on a specific port (that is pogo-pin based: not a standard USB port). This new sysfs option makes it possible to use the old scheme on a single port only.

2018-05-31btrfs: Add unprivileged version of ino_lookup ioctlTomohiro Misono
Add unprivileged version of ino_lookup ioctl BTRFS_IOC_INO_LOOKUP_USER to allow normal users to call "btrfs subvolume list/show" etc. in combination with BTRFS_IOC_GET_SUBVOL_INFO/BTRFS_IOC_GET_SUBVOL_ROOTREF. This can be used like BTRFS_IOC_INO_LOOKUP but the argument is different. This is because it always searches the fs/file tree correspoinding to the fd with which this ioctl is called and also returns the name of bottom subvolume. The main differences from original ino_lookup ioctl are: 1. Read + Exec permission will be checked using inode_permission() during path construction. -EACCES will be returned in case of failure. 2. Path construction will be stopped at the inode number which corresponds to the fd with which this ioctl is called. If constructed path does not exist under fd's inode, -EACCES will be returned. 3. The name of bottom subvolume is also searched and filled. Note that the maximum length of path is shorter 256 (BTRFS_VOL_NAME_MAX+1) bytes than ino_lookup ioctl because of space of subvolume's name.

2018-05-31btrfs: Add unprivileged ioctl which returns subvolume's ROOT_REFTomohiro Misono
Add unprivileged ioctl BTRFS_IOC_GET_SUBVOL_ROOTREF which returns ROOT_REF information of the subvolume containing this inode except the subvolume name (this is because to prevent potential name leak). The subvolume name will be gained by user version of ino_lookup ioctl (BTRFS_IOC_INO_LOOKUP_USER) which also performs permission check. The min id of root ref's subvolume to be searched is specified by @min_id in struct btrfs_ioctl_get_subvol_rootref_args. After the search ends, @min_id is set to the last searched root ref's subvolid + 1. Also, if there are more root refs than BTRFS_MAX_ROOTREF_BUFFER_NUM, -EOVERFLOW is returned. Therefore the caller can just call this ioctl again without changing the argument to continue search.

2018-05-31driver core: hold dev's parent lock when neededMartin Liu
SoC have internal I/O buses that can't be proved for devices. The devices on the buses can be accessed directly without additinal configuration required. This type of bus is represented as "simple-bus". In some platforms, we name "soc" with "simple-bus" attribute and many devices are hooked under it described in DT (device tree). In commit bf74ad5bc417 ("Hold the device's parent's lock during probe and remove") to solve USB subsystem lock sequence since USB device's characteristic. Thus "soc" needs to be locked whenever a device and driver's probing happen under "soc" bus. During this period, an async driver tries to probe a device which is under the "soc" bus would be blocked until previous driver finish the probing and release "soc" lock. And the next probing under the "soc" bus need to wait for async finish. Because of that, driver's async probe for init time improvement will be shadowed. Since many devices don't have USB devices' characteristic, they actually don't need parent's lock. Thus, we introduce a lock flag in bus_type struct and driver core would lock the parent lock base on the flag. For USB, we set this flag in usb_bus_type to keep original lock behavior in driver core. Async probe could have more benefit after this patch.

git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu Pull RCU fix from Paul E. McKenney: "This additional v4.18 pull request contains a single commit that fell through the cracks: Provide early rcu_cpu_starting() callback for the benefit of the x86/mtrr code, which needs RCU to be available on incoming CPUs earlier than has been the case in the past."

It is a CQE in compressed form that holds data needed to extra a single full CQE. It is a stride index, byte count and packet checksum. ==================== * mini_cqe: IB/mlx5: Introduce a new mini-CQE format IB/mlx5: Refactor CQE compression response net/mlx5: Exposing a new mini-CQE format Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2018-05-29IB/mlx5: Introduce a new mini-CQE formatYonatan Cohen
The new mini-CQE format includes the stride index, byte count and packet checksum. Stride index is needed for striding WQ feature. This patch exposes this capability and enables its setting via mlx5 UHW data as part of query device and cq creation.

2018-05-29bpf: Drop mpls from bpf_fib_lookupDavid Ahern
MPLS support will not be submitted this dev cycle, but in working on it I do see a few changes are needed to the API. For now, drop mpls from the API. Since the fields in question are unions, the mpls fields can be added back later without affecting the uapi.

2018-05-29bpf: clean up eBPF helpers documentationQuentin Monnet
These are minor edits for the eBPF helpers documentation in include/uapi/linux/bpf.h. The main fix consists in removing "BPF_FIB_LOOKUP_", because it ends with a non-escaped underscore that gets interpreted by rst2man and produces the following message in the resulting manual page: DOCUTILS SYSTEM MESSAGES System Message: ERROR/3 (/tmp/bpf-helpers.rst:, line 1514) Unknown target name: "bpf_fib_lookup". Other edits consist in: - Improving formatting for flag values for "bpf_fib_lookup()" helper. - Emphasising a parameter name in description of the return value for "bpf_get_stack()" helper. - Removing unnecessary blank lines between "Description" and "Return" sections for the few helpers that would use it, for consistency.

2018-05-29block: remove parent device reference from struct bsg_class_deviceChristoph Hellwig
Bsg holding a reference to the parent device may result in a crash if a bsg file handle is closed after the parent device driver has unloaded. Holding a reference is not really needed: the parent device must exist between bsg_register_queue and bsg_unregister_queue. Before the device goes away the caller does blk_cleanup_queue so that all in-flight requests to the device are gone and all new requests cannot pass beyond the queue. The queue itself is a refcounted object and it will stay alive with a bsg file. Based on analysis, previous patch and changelog from Anatoliy Glagolev.
