#     ocxl: do not use C++ style comments in uapi header
#     
#     Linux kernel tolerates C++ style comments these days. Actually, the
#     SPDX License tags for .c files start with //.
#     
#     On the other hand, uapi headers are written in more strict C, where
#     the C++ comment style is forbidden.

WARNING: vmlinux.o(.text+0x39c6): Section mismatch in reference from the variable start_here_multiplatform to the function .init.text:.early_setup()
The function start_here_multiplatform() references
the function __init .early_setup().
This is often because start_here_multiplatform lacks a __init 
annotation or the annotation of .early_setup is wrong.
