      powerpc: Enable sys_kcmp() for CRIU · 7978f76c
      Laurent Dufour authored
      The commit 8170a83f ("powerpc: Wireup the kcmp syscall to sys_ni") has
      disabled the kcmp syscall for powerpc.  This has been done due to the use
      of unsigned long parameters which may require a dedicated wrapper to handle
      32bit process on top of 64bit kernel.  However in the kcmp() case, the 2
      unsigned long parameters are currently only used to carry file descriptors
      from user space to the kernel.  Since such a parameter is passed through
      register, and file descriptor doesn't need to get extended, there is,
      today, no need for a wrapper.
      
      In the case there will be a need to pass address in or out of this system
      call, then a wrapper could be required, it will then be to care of it.
      
      As today this is not the case, it is safe to enable kcmp() on powerpc.
      
      Tested (by Laurent) on 64-bit, 32-bit, and 32-bit userspace on 64-bit
      kernel using tools/testing/selftests/kcmp [mpe].

      drm: Zero out invalid vblank timestamp in drm_update_vblank_count. · fdb68e09
      Mario Kleiner authored
      Since commit 844b03f2 we make
      sure that after vblank irq off, we return the last valid
      (vblank count, vblank timestamp) pair to clients, e.g., during
      modesets, which is good.
      
      An overlooked side effect of that commit for kms drivers without
      support for precise vblank timestamping is that at vblank irq
      enable, when we update the vblank counter from the hw counter, we
      can't update the corresponding vblank timestamp, so now we have a
      totally mismatched timestamp for the new count to confuse clients.
      
      Restore old client visible behaviour from before Linux 3.17, but
      zero out the timestamp at vblank counter update (instead of disable
      as in original implementation) if we can't generate a meaningful
      timestamp immediately for the new vblank counter. This will fix
      this regression, so callers know they need to retry again later
      if they need a valid timestamp, but at the same time preserves
      the improvements made in the commit mentioned above.
