2010-07-09	powerpc/pseries: Add WARN_ON() to request_event_sources_irqs() on irq allocation/request failure	Mark Nelson	1	-8/+15
	At the moment if request_event_sources_irqs() can't allocate or request the interrupt, it just does a KERN_ERR printk. This may be fine for the existing RAS code where if we miss an EPOW event it just means that the event won't be logged and if we miss one of the RAS errors then we could miss an event that we perhaps should take action on. But, for the upcoming IO events code that will use event-sources if we can't allocate or request the interrupt it means we'd potentially miss an interrupt from the device. So, let's add a WARN_ON() in this error case so that we're a bit more vocal when something's amiss. While we're at it, also use pr_err() to neaten the code up a bit.

2010-05-21	powerpc/pseries: Make request_ras_irqs() available to other pseries code	Mark Nelson	1	-0/+79
	At the moment only the RAS code uses event-sources interrupts (for EPOW events and internal errors) so request_ras_irqs() (which actually requests the event-sources interrupts) is found in ras.c and is static. We want to be able to use event-sources interrupts in other pseries code, so let's rename request_ras_irqs() to request_event_sources_irqs() and move it to event_sources.c. This will be used in an upcoming patch that adds support for IO Event interrupts that come through as event sources.
