Browse Source 
They are all device tree fixes which also worth being in stable:
 
  - Reserve PSCI area on Armada 7K/8K preventing the kernel accessing
    this area and crashing while doing it.
 
  - Use correct PCIe reset signal on MACCHIATOBin  (Armada 8040 based)
 
  - Fix polarity of GPIO fan line D-Link DNS NASes(kikwood based)
