Patch from Thomas Gleixner From: Thomas Gleixner <tglx@linutronix.de> Switch the ARM irq core handling to the generic implementation. The ARM specific header files now contain mostly migration stubs and helper macros. Note that each machine type must be converted after this step seperately. This was seperated out from the patch for easier review. The main changes for the machine type code is the conversion of the type handlers to a 'type flow' and 'chip' model. This affects only the multiplex interrupt handlers. A conversion macro needs to be added to those implementations, which defines the data structure which is registered by the set_irq_chained_handler() macro. Some minor fixups of include files and the conversion of data structure access is necessary all over the place. The mostly macro based conversion was provided to allow an easy migration of the existing implementations. The code compiles on all defconfigs available in arch/arm/configs except those which were broken also before applying the conversion patches. The code has been boot and runtime tested on most ARM platforms. The results of an extensive testing and bugfixing series can be found at: http://www.linutronix.de/index.php?page=testing Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
