<pre>Projects that manually specify linker scripts (via `-T` arg to linker) should
explicitly place these sections via their custom linker scripts.
For the aarch64 Linux kernel, arch/arm64/kernel/vmlinux.lds.S should be
modified, specifically the .text section output section listing should include
a list of these sections. Otherwise the linker may place these orphan code
sections outside of the _stext/_etext linker symbols which are used to denote a
boundary of code to be mapped at runtime, which is a common cause of boot
failures.
I don't think the toolchain should be modified to not place these thunks in
custom sections; I think the custom linker script used in the kernel should be
modified.</pre>
