      cpufreq: imx6q: Move speed grading check to cpufreq driver · 2b3d58a3
      Fabio Estevam authored
      On some i.MX6 SoCs (like i.MX6SL, i.MX6SX and i.MX6UL) that do not have
      speed grading check, opp table will not be created in platform code,
      so cpufreq driver prints the following error message:
      
      cpu cpu0: dev_pm_opp_get_opp_count: OPP table not found (-19)
      
      However, this is not really an error in this case because the
      imx6q-cpufreq driver first calls dev_pm_opp_get_opp_count()
      and if it fails, it means that platform code does not provide
      OPP and then dev_pm_opp_of_add_table() will be called.
      
      In order to avoid such confusing error message, move the speed grading
      check from platform code to the imx6q-cpufreq driver.
      
      This way the imx6q-cpufreq no longer has to check whether OPP table
      is supplied by platform code.
      
      Tested on a i.MX6Q and i.MX6UL based boards.

       "This contains the following fixes and improvements:
      
         - Avoid dereferencing an unprotected VMA pointer in the fault signal
           generation code
      
         - Fix inline asm call constraints for GCC 4.4
      
         - Use existing register variable to retrieve the stack pointer
           instead of forcing the compiler to create another indirect access
           which results in excessive extra 'mov %rsp, %<dst>' instructions
      
         - Disable branch profiling for the memory encryption code to prevent
           an early boot crash
      
         - Fix a sparse warning caused by casting the __user annotation in
           __get_user_asm_u64() away
      
         - Fix an off by one error in the loop termination of the error patch
           in the x86 sysfs init code
      
         - Add missing CPU IDs to various Intel specific drivers to enable the
           functionality on recent hardware
      
         - More (init) constification in the numachip code"

      Pull timer fixes from Thomas Gleixner:
       "This adds a new timer wheel function which is required for the
        conversion of the timer callback function from the 'unsigned long
        data' argument to 'struct timer_list *timer'. This conversion has two
        benefits:
      
         1) It makes struct timer_list smaller
      
         2) Many callers hand in a pointer to the timer or to the structure
            containing the timer, which happens via type casting both at setup
            and in the callback. This change gets rid of the typecasts.
      
        Once the conversion is complete, which is planned for 4.15, the old
        setup function and the intermediate typecast in the new setup function
        go away along with the data field in struct timer_list.
      
        Merging this now into mainline allows a smooth queueing of the actual
        conversion in the affected maintainer trees without creating
        dependencies"

        The lockdep splats are false positives, but there is no way to
