ia64 deletes __exit section during the final link stage of vmlinux.
This means that code should not call __exit functions in modules
that can be built in to the kernel.
Building with CONFIG_DEBUG_SECTION_MISMATCH=y we see these build messages:
WARNING: vmlinux.o(.init.text+0x22462): Section mismatch in reference from the function init_xfs_fs() to the function .exit.text:xfs_qm_exit()
The function __init init_xfs_fs() references
a function __exit xfs_qm_exit().
This is often seen when error handling in the init function
uses functionality in the exit path.
The fix is often to remove the __exit annotation of
xfs_qm_exit() so it may be used outside an exit section.
...
`xfs_qm_exit' referenced in section `.init.text' of fs/built-in.o: defined in discarded section `.exit.text' of fs/built-in.o
