From 3b0b6aa2cd05b516ecf4b72f9a3c2aadddf3c94e Mon Sep 17 00:00:00 2001 From: Andrew Turner Date: Mon, 9 Feb 2026 17:24:27 +0000 Subject: [PATCH] arm64: Panic if the ID register isn't known This will allow for callers to be simplified & not need to check the return status. Keep the return type for now so this can be MFCd without breaking the KBI.
