<stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp]
WARNING: vmlinux.o(.text+0x2fd0): Section mismatch in reference from the variable start_here_common to the function .init.text:start_kernel()
The function start_here_common() references
the function __init start_kernel().
This is often because start_here_common lacks a __init 
annotation or the annotation of start_kernel is wrong.
