      drm/msm: Fix removal of valid error case when checking speed_bin · 2b0b219e
      John Stultz authored
      Commit 7bf168c8  ("drm/msm: Fix speed-bin support not to
      access outside valid memory"), reworked the nvmem reading of
      "speed_bin", but in doing so dropped handling of the -ENOENT
      case which was previously documented as "fine".
      
      That change resulted in the db845c board display to fail to
      start, with the following error:
      
      adreno 5000000.gpu: [drm:a6xx_gpu_init] *ERROR* failed to read speed-bin (-2). Some OPPs may not be supported by hardware
      
      Thus, this patch simply re-adds the ENOENT handling so the lack
      of the speed_bin entry isn't fatal for display, and gets things
      working on db845c.

      drm/msm: Set drvdata to NULL when msm_drm_init() fails · 5620b135
      Stephen Boyd authored
      We should set the platform device's driver data to NULL here so that
      code doesn't assume the struct drm_device pointer is valid when it could
      have been destroyed. The lifetime of this pointer is managed by a kref
      but when msm_drm_init() fails we call drm_dev_put() on the pointer which
      will free the pointer's memory. This driver uses the component model, so
      there's sort of two "probes" in this file, one for the platform device
      i.e. msm_pdev_probe() and one for the component i.e. msm_drm_bind(). The
      msm_drm_bind() code is using the platform device's driver data to store
      struct drm_device so the two functions are intertwined.
      
      This relationship becomes a problem for msm_pdev_shutdown() when it
      tests the NULL-ness of the pointer to see if it should call
      drm_atomic_helper_shutdown(). The NULL test is a proxy check for if the
      pointer has been freed by kref_put(). If the drm_device has been
      destroyed, then we shouldn't call the shutdown helper, and we know that
      is the case if msm_drm_init() failed, therefore set the driver data to
      NULL so that this pointer liveness is tracked properly.

      will copy 1 byte from userspace to (quite big) on-stack array
      and then stash everything to mm->saved_auxv.
      AT_NULL terminator will be inserted at the very end.
      
      /proc/*/auxv handler will find that AT_NULL terminator
      and copy original stack contents to userspace.
      
      This devious scheme requires CAP_SYS_RESOURCE.

       - A couple of SEV-ES fixes and robustifications: verify usermode stack
         pointer in NMI is not coming from the syscall gap, correctly track
         IRQ states in the #VC handler and access user insn bytes atomically
         in same handler as latter cannot sleep.
      
       - Balance 32-bit fast syscall exit path to do the proper work on exit
         and thus not confuse audit and ptrace frameworks.
      
       - Two fixes for the ORC unwinder going "off the rails" into KASAN
         redzones and when ORC data is missing.

       "Some more powerpc fixes for 5.12:
      
         - Fix wrong instruction encoding for lis in ppc_function_entry(),
           which could potentially lead to missed kprobes.
      
         - Fix SET_FULL_REGS on 32-bit and 64e, which prevented ptrace of
           non-volatile GPRs immediately after exec.
      
         - Clean up a missed SRR specifier in the recent interrupt rework.
      
         - Don't treat unrecoverable_exception() as an interrupt handler, it's
           called from other handlers so shouldn't do the interrupt entry/exit
           accounting itself.
