Anton Blanchard 55fc0c5617 powerpc/pseries: Parse and handle EPOW interrupts ... We have code to take environmental and power warning (EPOW) interrupts but it simply prints a terse error message: EPOW <0x6240040000000b8 0x0 0x0> which tells us nothing about what happened. Even worse, if we don't correctly respond to the interrupt we may get terminated by firmware. Add code to printk some useful information when we get EPOW events. We want to make it clear that we have an error, that it was reported by firmware and that the RTAS error log will have more detailed information. eg: Ambient temperature too high reported by firmware. Check RTAS error log for details Depending on the error encountered, we now issue an immediate or an orderly power down. Move initialization of the EPOW interrupt earlier in boot since we want to respond to them as early as possible.
