2020-05-27drm: Shrink drm_display_mode timingsVille Syrjälä
Store the timings (apart from the clock) as u16. The uapi mode struct already uses u16 for everything so using something bigger internally doesn't really help us.

2020-05-27drm: Shrink {width,height}_mm to u16Ville Syrjälä
Instead of supporting ~2000km wide displayes let's limit ourselves to ~65m. That seems plenty big enough to me. Even with EDID_QUIRK_DETAILED_IN_CM EDIDs seem to be limited to 10*0xfff which fits into the 16 bits.

2020-05-20dma-fence: add might_sleep annotation to _wait()Daniel Vetter
Do it uncontionally, there's a separate peek function with dma_fence_is_signalled() which can be called from atomic context. v2: Consensus calls for an unconditional might_sleep (Chris, Christian) Full audit: - dma-fence.h: Uses MAX_SCHEDULE_TIMOUT, good chance this sleeps - dma-resv.c: Timeout always at least 1 - st-dma-fence.c: Save to sleep in testcases - amdgpu_cs.c: Both callers are for variants of the wait ioctl - amdgpu_device.c: Two callers in vram recover code, both right next to mutex_lock. - amdgpu_vm.c: Use in the vm_wait ioctl, next to _reserve/unreserve - remaining functions in amdgpu: All for test_ib implementations for various engines, caller for that looks all safe (debugfs, driver load, reset) - etnaviv: another wait ioctl - habanalabs: another wait ioctl - nouveau_fence.c: hardcoded 15*HZ ... glorious - nouveau_gem.c: hardcoded 2*HZ ... so not even super consistent, but this one does have a WARN_ON :-/ At least this one is only a fallback path for when kmalloc fails. Maybe this should be put onto some worker list instead, instead of a work per unamp ... - i915/selftests: Hardecoded HZ / 4 or HZ / 8 - i915/gt/selftests: Going up the callchain looks safe looking at nearby callers - i915/gt/intel_gt_requests.c.
