      ACPI: video: Stop trying to use vendor backlight control on laptops from after ~2012 · aa8a950a
      Hans de Goede authored
      There have been 2 separate reports now about a non working
      "dell_backlight" device getting registered under /sys/class/backlight
      1 report for a Raptor Lake based Dell and 1 report for a Meteor Lake
      (development) platform.
      
      On hw from the last 10 years dell-laptop will not register "dell_backlight"
      because acpi_video_get_backlight_type() will return acpi_backlight_video
      there if called before the GPU/kms driver loads. So it does not matter if
      the GPU driver's native backlight is registered after dell-laptop loads.
      
      But it seems that on the latest generation laptops the ACPI tables
      no longer contain acpi_video backlight control support which causes
      acpi_video_get_backlight_type() to return acpi_backlight_vendor causing
      "dell_backlight" to get registered if the dell-laptop module is loaded
      before the GPU/kms driver.
      
      Vendor specific backlight control like the "dell_backlight" device is
      only necessary on quite old hw (from before acpi_video backlight control
      was introduced). Work around "dell_backlight" registering on very new
      hw (where acpi_video backlight control seems to be no more) by making
      acpi_video_get_backlight_type() return acpi_backlight_none instead
      of acpi_backlight_vendor as final fallback when the ACPI tables have
      support for Windows 8 or later (laptops from after ~2012).

      x86/retbleed: Fix return thunk alignment · 9a48d604
      Borislav Petkov (AMD) authored
      SYM_FUNC_START_LOCAL_NOALIGN() adds an endbr leading to this layout
      (leaving only the last 2 bytes of the address):
      
        3bff <zen_untrain_ret>:
        3bff:       f3 0f 1e fa             endbr64
        3c03:       f6                      test   $0xcc,%bl
      
        3c04 <__x86_return_thunk>:
        3c04:       c3                      ret
        3c05:       cc                      int3
        3c06:       0f ae e8                lfence
      
      However, "the RET at __x86_return_thunk must be on a 64 byte boundary,
      for alignment within the BTB."
      
      Use SYM_START instead.

         is used in deduplication tools

         free-space-tree instead of temporarily disabling it that would lead
         to a forced read-only mount
