[PATCH] irqchip: gic: ignore empty processor target registers

2015-01-30 Thread Stefan Agner
On initialization time, the GIC driver reads the processor target register (ICDIPTR) to determine the CPU's mask. On uniprocessor systems with GIC controller (e.g. Cortex-A5 SoC's) this register is RAZ/WI and hence the mask ends up being zero. This leads to the somewhat confusing boot message: [
