Fedora 38 (beta..) has GCC 13, and this causes an error when compiling the kernel with ‘gcc_plugins‘ selected:

# gcc –version
gcc (GCC) 13.0.1 20230215 (Red Hat 13.0.1-0)

The workaround is to simply de-select ‘gcc_plugins’ in the kernel config, but if you need this, then there is a patch – and more info – at:   https://www.spinics.net/lists/kernel/msg4674124.html

I have applied this to Kernel 6.2 on Fedora 38 / GCC 13.0.1, and the kernel compile etc. now works OK..
