From ca38701935138a4aba7dd9e4daf21e13a4663f43 Mon Sep 17 00:00:00 2001 From: "Pedro H. Penna" Date: Fri, 30 Jun 2017 08:33:56 -0300 Subject: [PATCH] irqchip/or1k-pic: Fix interrupt acknowledgement Usually, hardware implicitly acknowledges interrupts when reading them. However, if this is not the case, the IRQ gets fired over and over again in the current implementation. This patch uses the right mask acknowledge function to handle the aforementioned situation on or1k processors that interact with such kind of hardware.
