2016-11-30net: phy: bcm7xxx: Plug in support for reading PHY error countersFlorian Fainelli
Broadcom BCM7xxx internal PHYs can leverage the Broadcom PHY library module PHY error counters helper functions, just implement the appropriate PHY driver function calls to do so. We need to allocate some storage space for our PHY statistics, and provide it to the Broadcom PHY library, so do this in a specific probe function, and slightly wrap the get_stats function call.

Since the Broadcom PHY library code is used by several drivers, make it possible for them to specify the storage for the software copy of the statistics.

2016-11-30sfc: separate out SFC4000 ("Falcon") support into new sfc-falcon driverEdward Cree
Rationale: The differences between Falcon and Siena are in many ways larger than those between Siena and EF10 (despite Siena being nominally "Falcon- architecture"); for instance, Falcon has no MCPU, so there is no MCDI. Removing Falcon support from the sfc driver should simplify the latter, and avoid the possibility of Falcon support being broken by changes to sfc (which are rarely if ever tested on Falcon, it being end-of-lifed hardware). The sfc-falcon driver created in this changeset is essentially a copy of the sfc driver, but with Siena- and EF10-specific code, including MCDI, removed and with the "efx_" identifier prefix changed to "ef4_" (for "EFX 4000- series") to avoid collisions when both drivers are built-in. This changeset removes Falcon from the sfc driver's PCI ID table; then in sfc I've removed obvious Falcon-related code: I removed the Falcon NIC functions, Falcon PHY code, and EFX_REV_FALCON_*, then fixed up everything that referenced them. Also, increment minor version of both drivers (to 4.1). For now, CONFIG_SFC selects CONFIG_SFC_FALCON, so that updating old configs doesn't cause Falcon support to disappear; but that should be undone at some point in the future.

2016-11-30drm/bridge: Add ti-tfp410 DVI transmitter driverJyri Sarha
Add very basic ti-tfp410 DVI transmitter driver. The only feature separating this from a completely dummy bridge is the EDID read support trough DDC I2C. Even that functionality should be in a separate generic connector driver. However, because of missing DRM infrastructure support the connector is implemented within the bridge driver. Some tfp410 HW specific features may be added later if needed, because there is a set of registers behind i2c if it is connected. This implementation is tested against my new tilcdc bridge support and it works with BeagleBone DVI-D Cape Rev A3. A DT binding document is also updated.

2016-11-30drm/tilcdc: Recover from sync lost error flood by resetting the LCDCJyri Sarha
Recover from sync lost error flood by resetting the LCDC instead of turning off the SYNC_LOST error IRQ. When LCDC starves on limited memory bandwidth it may sometimes result an error situation when the picture may have shifted couple of pixels to right and SYNC_LOST interrupt is generated on every frame. LCDC main reset recovers from this situation and causes a brief blanking on the screen. Signed-off-by: Jyri Sarha <jsarha@ti.com> Tested-by: Bartosz Golaszewski <bgolaszewski@baylibre.com>

2016-11-30drm: Don't call drm_for_each_crtc with a non-KMS driverMichel Dänzer
Fixes oops if userspace calls DRM_IOCTL_GET_CAP for DRM_CAP_PAGE_FLIP_TARGET on a non-KMS device node. (Normal userspace doesn't do that, discovered by syzkaller) Reported-by: Dmitry Vyukov <dvyukov@google.com> Fixes: f837297ad824 ("drm: Add DRM_MODE_PAGE_FLIP_TARGET_ABSOLUTE/RELATIVE flags v2") Cc: stable@vger.kernel.org Signed-off-by: Michel Dänzer <michel.daenzer@amd.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20161130083002.1520-1-michel@daenzer.net
2016-11-30sched/x86: Change CONFIG_SCHED_ITMT to CONFIG_SCHED_MC_PRIOTim Chen
Rename CONFIG_SCHED_ITMT for Intel Turbo Boost Max Technology 3.0 to CONFIG_SCHED_MC_PRIO. This makes the configuration extensible in future to other architectures that wish to similarly establish CPU core priorities support in the scheduler. The description in Kconfig is updated to reflect this change with added details for better clarity. The configuration is explicitly default-y, to enable the feature on CPUs that have this feature. It has no effect on non-TBM3 CPUs.

2016-11-30xen/events: use xen_vcpu_id mapping for EVTCHNOP_statusVitaly Kuznetsov
EVTCHNOP_status hypercall returns Xen's idea of vcpu id so we need to compare it against xen_vcpu_id mapping, not the Linux cpu id.
