2018-01-23media: lirc: lirc daemon fails to detect raw IR deviceSean Young1-13/+11
Since commit 9b6192589be7 ("media: lirc: implement scancode sending"), and commit de142c324106 ("media: lirc: implement reading scancode") the lirc features ioctl for raw IR devices advertises two modes for sending and receiving. The lirc daemon now fails to detect a raw IR device, both for transmit and receive. To fix this, do not advertise the scancode mode in the lirc features for raw IR devices (however do keep it for scancode devices). The mode can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

2018-01-23sysfs: add attribute specification for /sysfs/devices/.../coredumpArend van Spriel1-0/+10
This patch adds the specification for /sysfs/devices/.../coredump which allows user-space to trigger a device coredump obtaining binary data from the device for (fault) analysis. It relies on CONFIG_DEV_COREDUMP being enabled. Signed-off-by: Arend van Spriel <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>

2018-01-22sparc64: Oracle DAX driverRob Gardner2-0/+1862
DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8 (DAX2) processor chips, and has direct access to the CPU's L3 caches as well as physical memory. It can perform several operations on data streams with various input and output formats. This driver provides a transport mechanism and has limited knowledge of the various opcodes and data formats. A user space library provides high level services and translates these into low level commands which are then passed into the driver and subsequently the hypervisor and the coprocessor. The library is the recommended way for applications to use the coprocessor, and the driver interface is not intended for general use.

ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/dt Pull "Few omap interconnect dts fixes for v4.16 merge window" from Tony Lindgren: Now that we have the dts clocks for the clkctrl clock and the interconnect binding, we need to update the existing ti-sysc users according to the binding to make it usable for drivers. Apologies for not being able to send this earlier but it took me few revisions to get the smartreflex changes right and tested with yet to be posted patches to make smartreflex probe with dts and I wanted to have it sit in next for a while to make sure we're not introducing regressions for legacy platform data based booting. Note that this is based on a merge with commit 20a2742e5784 ("dt-bindings: ti-sysc: Update binding for timers and capabilities") to avoid a merge conflict with the binding changes. * tag 'omap-for-v4.16/dt-clk-dts-signed' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: dts: Update ti-sysc data for existing users ARM: dts: Fix smartreflex compatible for omap3 shared mpu-iva instance dt-bindings: ti-sysc: Update binding for timers and capabilities

2018-01-19KVM: PPC: Book3S: Provide information about hardware/firmware CVE workaroundsPaul Mackerras1-0/+46
This adds a new ioctl, KVM_PPC_GET_CPU_CHAR, that gives userspace information about the underlying machine's level of vulnerability to the recently announced vulnerabilities CVE-2017-5715, CVE-2017-5753 and CVE-2017-5754, and whether the machine provides instructions to assist software to work around the vulnerabilities. The ioctl returns two u64 words describing characteristics of the CPU and required software behaviour respectively, plus two mask words which indicate which bits have been filled in by the kernel, for extensibility. The bit definitions are the same as for the new H_GET_CPU_CHARACTERISTICS hypercall. There is also a new capability, KVM_CAP_PPC_GET_CPU_CHAR, which indicates whether the new ioctl is available.
