+Subject: [PATCH] irqchip: Move IRQCHIP_DECLARE macro to
+ include/linux/irqchip.h
+
+At the moment the IRQCHIP_DECLARE macro is only declared locally in
+drivers/irqchip/irqchip.h. It prevents from using it directly in arch/*
+directories whenever irqchip drivers only exist there, which happens in a few
+cases (e.g. arc, arm, microblaze and mips).
+
+This patch makes the macro to be globally defined, i.e. in
+include/linux/irqchip.h, and thus usable for arch-specific declarations of
+irqchip drivers. In this way, it is very similar to what clocksource does (ie
+CLOCKSOURCE_OF_DECLARE is defined in include/linux/clocksource.h).
+
+For now, this patch only moves the declaration of the macro
+IRQCHIP_DECLARE to the global header 'include/linux/irqchip.h' and make
+'drivers/irqchip/irqchip.h' include 'include/linux/irqchip.h'. Later, other
+patches will get rid of 'drivers/irqchip/irqchip.h' and modify all the impacted
+irqchip drivers.
