ARM: 8103/1: save/restore Cortex-A9 CP15 registers on suspend/resume The CP15 diagnostic register holds ARM errata bits on Cortex-A9, so it needs to be saved/restored on suspend/resume. Otherwise, the effectiveness of errata workaround gets lost together with diagnostic register bit across suspend/resume cycle. And the CP15 power control register of Cortex-A9 shares the same problem. The patch adds a couple of Cortex-A9 specific suspend/resume functions to save/restore these two Cortex-A9 CP15 registers across the suspend/resume cycle.
