From caacdbf4aa567ab5e8de1a4070195c5d3e8f1340 Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Wed, 7 Mar 2018 15:57:27 -0800 Subject: genirq: Add CONFIG_GENERIC_IRQ_MULTI_HANDLER The arm multi irq handler registration mechanism has been copied into a handful of architectures, including arm64 and openrisc. RISC-V needs the same mechanism. Instead of adding yet another copy for RISC-V copy the arm implementation into the core code depending on a new Kconfig symbol: CONFIG_GENERIC_MULTI_IRQ_HANDLER. Subsequent patches will convert the various architectures.
