2016-12-30drm/cma-helpers: Use recommened kerneldoc for struct member refsDaniel Vetter
I just learned that &struct_name.member_name works and looks pretty even. It doesn't (yet) link to the member directly though, which would be really good for big structures or vfunc tables (where the per-member kerneldoc tends to be long). Also some minor drive-by polish where it makes sense, I read a lot of docs ... v2: Review from Laurent: - Move misplaced doc change to the right patch. - Remove "DRM driver's", it's redundant. - Spotted 3 more places where where we could add prose reference with a real one.

2016-12-30drm/cma-helper: simplify setup for drivers with ->dirty callbacksDaniel Vetter
If we store the fb funcs pointer, we can remove a bit of boilerplate. Also remove the _fbdev_ in the example code, since the fb_funcs->dirty callback has nothing to do with fbdev. It's a KMS feature, only used by the fbdev deferred_io support to implement flushing/upload.

I reported the include issue for tracepoints a while ago, but nothing seems to have happened. Now it bit us, since the drm_mm_print conversion was broken for armada.

2016-12-30arm64: dts: vexpress: Support GICC_DIR operationsSudeep Holla
The GICv2 CPU interface registers span across 8K, not 4K as indicated in the DT. Only the GICC_DIR register is located after the initial 4K boundary, leaving a functional system but without support for separately EOI'ing and deactivating interrupts. After this change the system supports split priority drop and interrupt deactivation.

Using ancient compilers (gcc-4.5 or older) on ARM, we get a link failure with the vfio-pci driver: ERROR: "__aeabi_lcmp" [drivers/vfio/pci/vfio-pci.ko] undefined!

2016-12-30vfio-mdev: Fix remove raceAlex Williamson
Using the mtty mdev sample driver we can generate a remove race by starting one shell that continuously creates mtty devices and several other shells all attempting to remove devices, in my case four remove shells. The fault occurs in mdev_remove_sysfs_files() where the passed type arg is NULL, which suggests we've received a struct device in mdev_device_remove() but it's in some sort of teardown state. The solution here is to make use of the accidentally unused list_head on the mdev_device such that the mdev core keeps a list of all the mdev devices. This allows us to validate that we have a valid mdev before we start removal, remove it from the list to prevent others from working on it, and if the vendor driver refuses to remove, we can re-add it to the list.

2016-12-30vfio/type1: Restore mapping performance with mdev supportAlex Williamson
As part of the mdev support, type1 now gets a task reference per vfio_dma and uses that to get an mm reference for the task while working on accounting. That's correct, but it's not fast. For some paths, like vfio_pin_pages_remote(), we know we're only called from user context, so we can restore the lighter weight calls. In other cases, we're effectively already testing whether we're in the stored task context elsewhere, extend this vfio_lock_acct() as well.

2016-12-30firmware: arm_scpi: fix reading sensor values on pre-1.0 SCPI firmwaresMartin Blumenstingl
The pre-1.0 SCPI firmwares are using single __le32 as sensor value, while the SCPI v1.0 protocol uses two __le32 as sensor values(64bit) split into 32bit upper and 32bit lower value. Using an "struct sensor_value" to read the sensor value on a pre-1.0 SCPI firmware gives garbage in the "hi_val" field. This patch fixes the issue by reading only the lower 32-bit value for all pre-1.0 SCPI versions.

The function intel_shared_dpll_commit() performs the equivalent of drm_atomic_helper_swap_state() for the shared dpll state, which is not handled by the helpers. So make it do a full swap of the state and rename it for consistency. v2: Fix typo in the commit message. (Durga) v3: Rebase. v4: Swap the states instead of just renaming the function.

2016-12-30drm/i915: Introduce intel_release_shared_dpll()Ander Conselvan de Oliveira
While the details of getting a shared dpll are wrapped by intel_get_shared_dpll(), the release was still hand rolled into the modeset code. Fix that by creating an entry point for releasing the pll and move that code there. v2: Take old_dpll from crtc->state instead of crtc_state.

2016-12-29net: ipv4: dst for local input routes should use l3mdev if relevantDavid Ahern
IPv4 output routes already use l3mdev device instead of loopback for dst's if it is applicable. Change local input routes to do the same. This fixes icmp responses for unreachable UDP ports which are directed to the wrong table after commit 9d1a6c4ea43e4 because local_input routes use the loopback device. Moving from ingress device to loopback loses the L3 domain causing responses based on the dst to get to lost.

2016-12-29parisc: Mark cr16 clocksource unstable on SMP systemsHelge Deller
The cr16 interval timer of each CPU is not syncronized to other cr16 timers in other CPUs in a SMP system. So, delay the registration of the cr16 clocksource until all CPUs have been detected and then - if we are on a SMP machine - mark the cr16 clocksource as unstable and lower it's rating before registering it at the clocksource framework. This patch fixes the stalled CPU warnings which we have seen since introduction of the cr16 clocksource. Signed-off-by: Helge Deller <deller@gmx.de> Cc: <stable@vger.kernel.org> # v4.8+
