2018-03-08drm/amd/display: disable CRTCs with NULL FB on their primary plane (V2)Shirish S1-0/+28
The below commit "drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2" introduces a slight behavioral change to rmfb. Instead of disabling a crtc when the primary plane is disabled, it now preserves it. This change leads to BUG hit while performing atomic commit on amd driver. As a fix this patch ensures that we disable the CRTC's with NULL FB by returning -EINVAL and hence triggering fall back to the old behavior and turning off the crtc in atomic_remove_fb(). V2: Added error check for plane_state and removed sanity check for crtc.

There have been many reports of Ellesmere and Baffin systems not being able to drive HDMI 4k60 due to the fact that we check the HDMI_6GB_EN bit from VBIOS table. Windows seems to not have this issue. On some systems we fail to the encoder cap info from VBIOS. In that case we should default to enabling HDMI6G support.

2018-03-08drm/amd/display: defer modeset check in dm_update_planes_stateShirish S1-2/+4
amdgpu_dm_atomic_check() is used to validate the entire configuration of planes and crtc's that the user space wants to commit. However amdgpu_dm_atomic_check() depends upon DRM_MODE_ATOMIC_ALLOW_MODESET flag else its mostly dummy. Its not mandatory for the user space to set DRM_MODE_ATOMIC_ALLOW_MODESET, and in general its not set either along with DRM_MODE_ATOMIC_TEST_ONLY. Considering its importantance, this patch defers the allow_modeset check in dm_update_planes_state(), so that there shall be scope to validate the configuration sent from user space, without impacting the population of dc/dm related data structures.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: - Add handling for a missing instruction in our 32-bit BPF JIT so that it can be used for seccomp filtering. - Add a missing NULL pointer check before a function call in new EEH code. - Fix an error path in the new ocxl driver to correctly return EFAULT. - The support for the new ibm,drc-info device tree property turns out to need several fixes, so for now we just stop advertising to firmware that we support it until the bugs can be ironed out. - One fix for the new drmem code which was incorrectly modifying the device tree in place. - Finally two fixes for the RFI flush support, so that firmware can advertise to us that it should be disabled entirely so as not to affect performance.

Pull networking fixes from David Miller: 1) Fix TTL offset calculation in mac80211 mesh code, from Peter Oh. 2) Fix races with procfs in ipt_CLUSTERIP, from Cong Wang. 3) Memory leak fix in lpm_trie BPF map code, from Yonghong Song. 4) Need to use GFP_ATOMIC in BPF cpumap allocations, from Jason Wang. 5) Fix potential deadlocks in netfilter getsockopt() code paths, from Paolo Abeni. 6) Netfilter stackpointer size checks really are needed to validate user input, from Florian Westphal. 7) Missing timer init in x_tables, from Paolo Abeni. 8) Don't use WQ_MEM_RECLAIM in mac80211 hwsim, from Johannes Berg. 9) When an ibmvnic device is brought down then back up again, it can be sent queue entries from a previous session, handle this properly instead of crashing. From Thomas Falcon. 10) Fix TCP checksum on LRO buffers in mlx5e, from Gal Pressman. 11) When we are dumping filters in cls_api, the output SKB is empty, and the filter we are dumping is too large for the space in the SKB, we should return -EMSGSIZE like other netlink dump operations do. Otherwise userland has no signal that is needs to increase the size of its read buffer. From Roman Kapl. 12) Several XDP fixes for virtio_net, from Jesper Dangaard Brouer. 13) Module refcount leak in netlink when a dump start fails, from Jason Donenfeld. 14) Handle sub-optimal GSO sizes better in TCP BBR congestion control, from Eric Dumazet. 15) Releasing bpf per-cpu arraymaps can take a long time, add a condtional scheduling point. From Eric Dumazet. 16) Implement retpolines for tail calls in x64 and arm64 bpf JITs.
