From 9757d5c4fc3f7e4ab8cab07c4642194f57c551fc Mon Sep 17 00:00:00 2001 From: Shaoying Xu Date: Tue, 16 Feb 2021 18:32:34 +0000 Subject: [PATCH] arm64 module: set plt* section addresses to 0x0 commit f5c6d0fcf90ce07ee0d686d465b19b247ebd5ed7 upstream. These plt* and .text.ftrace_trampoline sections specified for arm64 have non-zero addressses. Non-zero section addresses in a relocatable ELF would confuse GDB when it tries to compute the section offsets and it ends up printing wrong symbol addresses. Therefore, set them to zero, which mirrors the change in commit 5d8591bc0fba ("module: set ksymtab/kcrctab* section addresses to 0x0").
