      drm/radeon: Fix kernel panic on shutdown · 0a6e2105
      Larry Finger 提交于
      Since commit a481daa8 ("drm/radeon: always apply pci shutdown
      callbacks"), a Dell Latitude D600 laptop has crashed on shutdown. The
      PCI Identification of the graphics adapter is "VGA compatible controller
      [0300]: Advanced Micro Devices, Inc. [AMD/ATI] RV250/M9 GL [Mobility
      FireGL 9000/Radeon 9000] [1002:4c66] (rev 01)".
      
      Prior to commit b0c80bd5 ("drm/radeon: fix up dp aux tear down (v2)"),
      I have no idea where the panic happened as the screen was blanked before
      the crash.  Since that more recent change, the panic has been in routine
      radeon_connector_unregister(), and has been shown to be due to a NULL
      value in the ddc_bus member of struct drm_connector.

       "Here are some mmc fixes intended for v4.9 rc2.
      
        This time I have also included a few changes for a memstick driver
        which has a corresponding mmc driver. They use the same USB device as
        parent, hence both needs to play nice with runtime PM, which they
        didn't.
      
        MMC core:
         - Update MAINTAINERS as the mmc tree moved to kernel.org
         - A few fixes for HS400es mode
         - A few other minor fixes

         - sdhci: Fix an issue when dealing with stop commands

      cpufreq: fix overflow in cpufreq_table_find_index_dl() · c6fe46a7

      'best' is always less or equals to 'pos', so `best - pos' returns
      a negative value which is then getting casted to `unsigned int'
      and passed to __cpufreq_driver_target()->acpi_cpufreq_target()

      arm64: remove pr_cont abuse from mem_init · f7881bd6
      Mark Rutland 提交于
      All the lines printed by mem_init are independent, with each ending with
      a newline. While they logically form a large block, none are actually
      continuations of previous lines.
      
      The kernel-side printk code and the userspace demsg tool differ in their
      handling of KERN_CONT following a newline, and while this isn't always a
      problem kernel-side, it does cause difficulty for userspace. Using
      pr_cont causes the userspace tool to not print line prefix (e.g.
      timestamps) even when following a newline, mis-aligning the output and
      making it harder to read, e.g.
