From bbb0dfa3773f263c5f99e0ea0684ad2074383ce9 Mon Sep 17 00:00:00 2001 From: Joakim Tjernlund Date: Mon, 14 Feb 2022 18:56:43 +0100 Subject: [PATCH] UPSTREAM: arm64: Correct wrong label in macro __init_el2_gicv3 In commit: 114945d84a30a5fe ("arm64: Fix labels in el2_setup macros") We renamed a label from '1' to '.Lskip_gicv3_\@', but failed to update a branch to it, which now targets a later label also called '1'. The branch is taken rarely, when GICv3 is present but SRE is disabled at EL3, causing a boot-time crash. Update the caller to the new label name.
