2018-12-17PCI: Override Synopsys USB 3.x HAPS device classThinh Nguyen
Synopsys USB 3.x host HAPS platform has a class code of PCI_CLASS_SERIAL_USB_XHCI, and xhci driver can claim it. However, these devices should use dwc3-haps driver. Change these devices' class code to PCI_CLASS_SERIAL_USB_DEVICE to prevent the xhci-pci driver from claiming them.

2018-12-17pinctrl: xway: fix gpio-hog related boot issuesMartin Schiller
This patch is based on commit a86caa9ba5d7 ("pinctrl: msm: fix gpio-hog related boot issues"). It fixes the issue that the gpio ranges needs to be defined before gpiochip_add(). Therefore, we also have to swap the order of registering the pinctrl driver and registering the gpio chip. You also have to add the "gpio-ranges" property to the pinctrl device node to get it finally working.

2018-12-17bpf: remove useless version check for prog loadDaniel Borkmann
Existing libraries and tracing frameworks work around this kernel version check by automatically deriving the kernel version from uname(3) or similar such that the user does not need to do it manually; these workarounds also make the version check useless at the same time. Moreover, most other BPF tracing types enabling bpf_probe_read()-like functionality have /not/ adapted this check, and in general these days it is well understood anyway that all the tracing programs are not stable with regards to future kernels as kernel internal data structures are subject to change from release to release. Back at last netconf we discussed [0] and agreed to remove this check from bpf_prog_load() and instead document it here in the uapi header that there is no such guarantee for stable API for these programs.

This patch adds support to run dual pipes simultaneously. A private ioctl to configure the pipe mode (video or still) is also implemented. IPU3 hardware supports a maximum of 2 streams per pipe. With the support of dual pipes, more than 2 stream outputs can be achieved. This helps to support advanced camera features like Continuous View Finder (CVF) and Snapshot During Video(SDV). Extend ipu3 IMGU driver to support dual pipes 1. Extend current IMGU device to contain 2 groups of video nodes and 2 subdevs 2. Extend current css to support 2 pipeline and make CSS APIs to support 2 pipe 3. Add a v4l2 ctrl to allow user to specify the mode of the pipe 4.

2018-12-17Merge branch 'next-integrity' of ↵James Morris
git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity into next-integrity From Mimi: In Linux 4.19, a new LSM hook named security_kernel_load_data was upstreamed, allowing LSMs and IMA to prevent the kexec_load syscall.  Different signature verification methods exist for verifying the kexec'ed kernel image.  This pull request adds additional support in IMA to prevent loading unsigned kernel images via the kexec_load syscall, independently of the IMA policy rules, based on the runtime "secure boot" flag.  An initial IMA kselftest is included. In addition, this pull request defines a new, separate keyring named ".platform" for storing the preboot/firmware keys needed for verifying the kexec'ed kernel image's signature and includes the associated IMA kexec usage of the ".platform" keyring. (David Howell's and Josh Boyer's patches for reading the preboot/firmware keys, which were previously posted for a different use case scenario, are included here.)
