From 7c576f4d3ce43fa0fc1ac258dc4768d0f3b3b992 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 13 Sep 2018 10:42:25 +0100 Subject: powerpc: Convert irq_domain_add_legacy_isa use to irq_domain_add_legacy irq_domain_add_legacy_isa is a pain. It only exists for the benefit of two PPC-specific drivers, and creates an ugly dependency between asm/irq.h and linux/irqdomain.h Instead, let's convert these two drivers to irq_domain_add_legacy(), stop using NUM_ISA_INTERRUPTS by directly setting NR_IRQS_LEGACY. The dependency cannot be broken yet as there is a lot of PPC-related code that depends on it, but that's the first step towards it. A followup patch will remove irq_domain_add_legacy_isa.
