Fedora rawhide recently upgraded to binutils 2.29 and this seems
to produce new warnings:

./arch/arm64/include/asm/assembler.h: Assembler messages:
./arch/arm64/include/asm/assembler.h:125: Warning: ignoring attempt to redefine built-in register 'lr'

This is

/*
 * Register aliases.
 */
lr      .req    x30             // link register

https://kojipkgs.fedoraproject.org//packages/kernel/4.13.0/0.rc2.git2.1.fc27/data/logs/aarch64/build.log
has an example log. As far as I can tell this doesn't affect anything at runtime.

Any ideas?

Thanks,
Laura
