[PATCH] kallsyms: Always include _edata
From: Christophe Leroy
Date: Wed Jan 08 2025 - 04:50:37 EST
Since commit 69a87a32f5cd ("perf machine: Include data symbols in the
kernel map"), perf needs _edata symbol.
Make sure it is always included in /proc/kallsyms and not only when
CONFIG_KALLSYMS_ALL is selected.
