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").
