      drm/etnaviv: make THERMAL selectable · 49b82c38
      Philipp Zabel authored
      The etnaviv driver causes a link failure if it is built-in but THERMAL
      is built as a module:
      
        drivers/gpu/drm/etnaviv/etnaviv_gpu.o: In function `etnaviv_gpu_bind':
        etnaviv_gpu.c:(.text+0x4c4): undefined reference to `thermal_of_cooling_device_register'
        etnaviv_gpu.c:(.text+0x600): undefined reference to `thermal_cooling_device_unregister'
        drivers/gpu/drm/etnaviv/etnaviv_gpu.o: In function `etnaviv_gpu_unbind':
        etnaviv_gpu.c:(.text+0x2aac): undefined reference to `thermal_cooling_device_unregister'
      
      Adding a Kconfig dependency on THERMAL || !THERMAL to avoid this causes
      a dependency loop on x86_64:
      
        drivers/gpu/drm/tve200/Kconfig:1:error: recursive dependency detected!
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/gpu/drm/tve200/Kconfig:1:       symbol DRM_TVE200 depends on CMA
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        mm/Kconfig:489: symbol CMA is selected by DRM_ETNAVIV
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/gpu/drm/etnaviv/Kconfig:2:      symbol DRM_ETNAVIV depends on THERMAL
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/thermal/Kconfig:5:      symbol THERMAL is selected by ACPI_VIDEO
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/acpi/Kconfig:189:       symbol ACPI_VIDEO is selected by BACKLIGHT_CLASS_DEVICE
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/video/backlight/Kconfig:158:    symbol BACKLIGHT_CLASS_DEVICE is selected by DRM_PARADE_PS8622
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/gpu/drm/bridge/Kconfig:62:      symbol DRM_PARADE_PS8622 depends on DRM_BRIDGE
        For a resolution refer to Documentation/kbuild/kconfig-language.txt
        subsection "Kconfig recursive dependency limitations"
        drivers/gpu/drm/bridge/Kconfig:1:       symbol DRM_BRIDGE is selected by DRM_TVE200
      
      To work around this, add a new option DRM_ETNAVIV_THERMAL to optionally
      enable thermal throttling support and make DRM_ETNAVIV select THERMAL
      at the same time.

      drm/etnaviv: Improve unlocking of a mutex in etnaviv_iommu_map_gem() · ff981595
      Markus Elfring authored
      Add a jump target so that a call of the function "mutex_unlock" is stored
      only once at the end of this function implementation.
      Replace three calls by goto statements.
      
      This issue was detected by using the Coccinelle software.

      ARM: BUG if jumping to usermode address in kernel mode · 8bafae20
      Russell King authored
      Detect if we are returning to usermode via the normal kernel exit paths
      but the saved PSR value indicates that we are in kernel mode.  This
      could occur due to corrupted stack state, which has been observed with
      "ftracetest".
      
      This ensures that we catch the problem case before we get to user code.
