modload fails to load any lkms, even ones that worked fine in
the past. I suspect this started happening after binutils was updated
in early February.
On amd64-current with Feb 19 kernel and userland:
ld: section .eh_frame [ffffffff80651768 -> ffffffff8065261f] overlaps section .data [ffffffff806525c0 -> ffffffff80652a27]
modload: can't link `/usr/lkm/udf.o' creating `/usr/lkm/udf' bound to 0xffffffff 8064c000
On alpha-current with June 14 kernel and userland:
ld: section .eh_frame [fffffe000c5a4750 -> fffffe000c5a47f7] overlaps section .data [fffffe000c5a47f0 -> fffffe000c5a48c7]
modload: can't link `nullfs.o' creating `nullfs' bound to 0xfffffe000c5a4000
Attempt to load an LKM with modload. E.g., modload /usr/lkm/nullfs.o
Modifying modload to call ld with the --no-check-sections flag
seems to work, but it seems that the way LKMs are built should be
changed so that the flag isn't required.
