!!!! THIS SOURCE IS NOT FOR THE RASPBERRY PI KERNEL !!!!
The kernel configuration file .config was taken from slackware-current
meant for use in 'huge' kernel 5.4.41 as slackware devs term it.
I've disabled the ORC unwinder and am instead using frame pointer in the below
location using <make menuconfig> and the kernel builds fine.
Kernel hacking -> Choose kernel unwinder
The kernel build generates errors like these if ORC unwinder is chosen and
ultimately fails:
