NEON error when crosscompiling aarch64

[Pavel Hofman]

Hi,

I have been cross-compiling previous aarch64 kernels for RPi on Ubuntu 
20.04 amd64 without any problem. Probably after some upgrade 
(unfortunately I do not know which), when compiling 5.17 with RPi HW 
patches (cloned from 
https://github.com/raspberrypi/linux/tree/rpi-5.17.y, but the same for 
5.18 RC1) I get the following errors:
