Do you know why we started creating these?

If it's intentional, should we be putting including them in the same
way as .hash sections?

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/powerpc/kernel/vmlinux.lds.S#n282

  .hash : AT(ADDR(.hash) - LOAD_OFFSET) { *(.hash) }

Cheers,

Joel
