Ugh, bad times for networking, I just "fixed" the HSR one a few hours
ago. Any idea what line of code this is? I'm dusting off my powerpc
build but the error is somewhat enigmatic.    

FWIW I couldn't reproduce this with these steps on top of
net-next/main (devmem TCP is there):

make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- ppc64_defconfig
make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- -j80

(build succeeds)

What am I doing wrong?  

I don't see it either, gcc 11.1. Given the burst of powerpc build
failures that just hit the list I'm wondering if this is real.

$ gcc --version
gcc (Debian 14.2.0-3) 14.2.0
$ ld --version
GNU ld (GNU Binutils for Debian) 2.43.1
$ as --version
GNU assembler (GNU Binutils for Debian) 2.43.1

All on a Powerpc 64 LE host.

FIIW, I have been able to reproduce this locally, on x86_64,
using the powerpc64 GCC-14.2.0 cross compiler from
https://mirrors.edge.kernel.org/pub/tools/crosstool/

make ARCH=powerpc CROSS_COMPILE=powerpc64-linux- ppc64_defconfig
make ARCH=powerpc CROSS_COMPILE=powerpc64-linux-
