powerpc/pseries: Add __init attribute to eligible functions Some functions defined in 'arch/powerpc/platforms/pseries' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.

powerpc/pseries: Use of_irq_get helper() in request_event_sources_irqs() Instead of calling both of_irq_parse_one() and irq_create_of_mapping(), call of_irq_get() instead which does essentially the same thing. of_irq_get() also calls irq_find_host() for deferred probe support, but this should be fine as irq_create_of_mapping() also calls that internally. This gets us closer to making the former 2 functions static. In the process of simplifying request_event_sources_irqs(), combine the the pr_err() and WARN_ON() calls to just a WARN().

powerpc: Remove all usages of NO_IRQ NO_IRQ has been == 0 on powerpc for just over ten years (since commit 0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change platforms to use it")). It's also 0 on most other arches. Although it's fairly harmless, every now and then it causes confusion when a driver is built on powerpc and another arch which doesn't define NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least some of which are to work around that problem. So we'd like to remove it. This is fairly trivial in the arch code, we just convert: if (irq == NO_IRQ) to if (!irq) if (irq != NO_IRQ) to if (irq) irq = NO_IRQ; to irq = 0; return NO_IRQ; to return 0; And a few other odd cases as well. At least for now we keep the #define NO_IRQ, because there is driver code that uses NO_IRQ and the fixes to remove those will go via other trees. Note we also change some occurrences in PPC sound drivers, drivers/ps3, and drivers/macintosh. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

of/irq: simplify args to irq_create_of_mapping All the callers of irq_create_of_mapping() pass the contents of a struct of_phandle_args structure to the function. Since all the callers already have an of_phandle_args pointer, why not pass it directly to irq_create_of_mapping()?

of/irq: Rename of_irq_map_* functions to of_irq_parse_* The OF irq handling code has been overloading the term 'map' to refer to both parsing the data in the device tree and mapping it to the internal linux irq system. This is probably because the device tree does have the concept of an 'interrupt-map' function for translating interrupt references from one node to another, but 'map' is still confusing when the primary purpose of some of the functions are to parse the DT data. This patch renames all the of_irq_map_* functions to of_irq_parse_* which makes it clear that there is a difference between the parsing phase and the mapping phase. Kernel code can make use of just the parsing or just the mapping support as needed by the subsystem. The patch was generated mechanically with a handful of sed commands.

powerpc/pseries: Add WARN_ON() to request_event_sources_irqs() on irq allocation/request failure 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.

powerpc/pseries: Make request_ras_irqs() available to other pseries code 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.
