From d5a5e4c93dae0dc3feb402cf7ee78d846da1a7e1 Mon Sep 17 00:00:00 2001 From: Aaron Lindsay Date: Thu, 26 Apr 2018 11:04:39 +0100 Subject: [PATCH] target/arm: Fetch GICv3 state directly from CPUARMState This eliminates the need for fetching it from el_change_hook_opaque, and allows for supporting multiple el_change_hooks without having to hack something together to find the registered opaque belonging to GICv3.
