When the kernel is compiled with -ffunction-sections and perf uses the
kernel debuginfo, perf fails the very first symbol lookup and ends up with
an hex offset inside [kernel.vmlinux]. It's due to how perf loads the maps.
Indeed only .text gets loaded by map_groups__find() into al->map.
When the kernel is compiled with -ffunction-sections and perf uses the
kernel debuginfo, perf fails the very first symbol lookup and ends up with
an hex offset inside [kernel.vmlinux]. It's due to how perf loads the maps.
