      drm: Add Grain Media GM12U320 driver v2 · e4f86e43
      Hans de Goede authored
      Add a modesetting driver for Grain Media GM12U320 based devices
      (primarily Acer C120 projector, but there may be compatible devices).
      
      This is based on the fb driver from Viacheslav Nurmekhamitov:
      https://github.com/slavrn/gm12u320
      
      This driver uses drm_simple_display_pipe to deal with all the atomic
      stuff, gem_shmem_helper functions for buffer management and
      drm_fbdev_generic_setup for fbdev emulation, so that leaves the driver
      itself with only the actual code for talking to the gm12u320 chip,
      leading to a nice simple and clean driver.
      
      Changes in v2:
      -Add drm-misc tree to MAINTAINERS
      -Drop mode_config.preferred_depth = 24 / fix fbdev support

      drm/fb: remove unused function: drm_gem_fbdev_fb_create() · 73415b4e
      Sam Ravnborg authored
      After migrating several drivers to the generic fbdev
      emulation there are no users left of drm_gem_fbdev_fb_create.
      Delete the function.
      
      Noticed that there was no callers while browsing
      around in the drm_fb* code.
      
      The code that referenced the function was removed by:
      commit 13aff184 ("drm/qxl: remove dead qxl fbdev emulation code")
      
      The actual use was removed by:
      commit 26d4707d ("drm/qxl: use generic fbdev emulation")
      
      v2:
      - Updated changelog based on feedback from Noralf

      iommu/amd: fix a crash in iova_magazine_free_pfns · 8cf66504
      Qian Cai authored
      The commit b3aa14f0 ("iommu: remove the mapping_error dma_map_ops
      method") incorrectly changed the checking from dma_ops_alloc_iova() in
      map_sg() causes a crash under memory pressure as dma_ops_alloc_iova()
      never return DMA_MAPPING_ERROR on failure but 0, so the error handling
      is all wrong.

      pte_free_kernel() and pte_free() is identical to the generic except of
      lack of __GFP_ACCOUNT for the user PTEs allocation.
