From 98552307e3a72d480e72744bf5da2a865822f496 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 18 May 2022 09:40:16 +0200 Subject: powerpc/irq64: Remove get_irq_happened() No need to open code the read of local_paca->irq_happened in assembly, we have READ_ONCE() for doing the same. Replace get_irq_happened() by READ_ONCE(local_paca->irq_happened).
