objdump -x of the linked kernel
While trying to link the FreeBSD arm64 kernel I received around 45141 of the
following error:
relocation R_AARCH64_ADR_PREL_PG_HI21 out of range
After commenting out the check I linked the kernel and found the orphaned
sections were placed at the end of the file and started with a virtual address
of 0. This caused an overflow in the relocation.
It would seem binutils has a heuristic to put these sections after a section
with similar attributes:
