[PATCH v6 1/4] irqchip: mips-gic: Add context saving for MIPS_REMOTEPROC

2017-03-23 Thread Matt Redfearn
The MIPS remote processor driver allows non-Linux firmware to take control of and execute on one of the systems VPEs. If that VPE is brought back under Linux, it is necessary to ensure that all GIC interrupts are routed and masked as Linux expects them, as the firmware can have done anything it
