2019-11-22ice: Don't modify stripping for add/del VLANs on VFBrett Creeley
Currently when adding/deleting vlans in ice_vc_process_vlan_msg() we are calling ice_vsi_manage_vlan_stripping() to enable/disable when adding and deleting a VLAN respectively. This is wrong because adding/deleting VLANs has nothing to do with configuring VLAN stripping. VLAN stripping is configured through the following VIRTCHNL operations: VIRTCHNL_OP_ENABLE_VLAN_STRIPPING VIRTCHNL_OP_DISABLE_VLAN_STRIPPING Unfortunately we can't just remove this because then stripping will never be configured on VF initialization. Fix this by adding a new function that initializes (disables/enables) VLAN stripping for the VF based on the device supported capabilities. This allows us to remove the call to ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

2019-11-22ice: Disallow VF VLAN opcodes if VLAN offloads disabledBrett Creeley
Currently if the host disables VLAN offloads on the VF by not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit we will still honor VF VLAN configuration messages over VIRTCHNL. These messages (i.e. enable/disable VLAN stripping and VLAN filtering) should be blocked when the feature is not supported. Fix that by adding a helper function to determine if the VF is allowed to do VLAN operations based on the host's VF configuration. Also, mirror the VF communicated capabilities in the host's VF configuration.

2019-11-22drm/amdgpu: invalidate mmhub semaphore workaround in gmc9/gmc10changzhu
It may lose gpuvm invalidate acknowldege state across power-gating off cycle. To avoid this issue in gmc9/gmc10 invalidation, add semaphore acquire before invalidation and semaphore release after invalidation. After adding semaphore acquire before invalidation, the semaphore register become read-only if another process try to acquire semaphore. Then it will not be able to release this semaphore. Then it may cause deadlock problem. If this deadlock problem happens, it needs a semaphore firmware fix.

2019-11-22ALSA: aloop: Remove redundant locking in timer open functionAndrew Gabbasov
loopback_parse_timer_id() uses snd_card_ref(), that can lock on mutex, also snd_timer_instance_new() uses non-atomic allocation, that can sleep. So, both functions can not be called from loopback_snd_timer_open() with cable->lock spinlock locked. Moreover, most part of loopback_snd_timer_open() function body works when the opposite stream of the same cable does not yet exist, and the current stream is not yet completely open and can't be running, so existing locking of loopback->cable_lock mutex is enough to protect from conflicts with simultaneous opening or closing. Locking of cable->lock spinlock is not needed in this case.
