Subject: Relocation (type 4) overflow on alpha for big module

I decided to try btrfs on one of my alphas and got a surprise - btrfs module does not load:

modprobe: ERROR: could not insert 'btrfs': Exec format error

dmesg has

module btrfs: Relocation (type 4) overflow vs btrfs_attach_transaction_barrier

Happens both natively on alpha:
binutils 2.30.0 (Gentoo 2.30 p2) and gcc version 7.3.0 (Gentoo 7.3.0-r3 p1.4)
or in cross-compiling:
binutils (GNU Binutils for Debian) 2.31.1 and gcc version 8.1.0 (Debian 8.1.0-12)

btrfs.ko has size 2939856. Build-in btrfs initializes and tests itself just fine.

This seems to have happened in the distant past:

Do we have a similar binutils problem again with big modules?
