#     kbuild: add -fcf-protection=none when using retpoline flags
#     
#     The gcc -fcf-protection=branch option is not compatible with
#     -mindirect-branch=thunk-extern. The latter is used when
#     CONFIG_RETPOLINE is selected, and this will fail to build with
#     a gcc which has -fcf-protection=branch enabled by default. Adding
#     -fcf-protection=none when building with retpoline enabled
#     prevents such build failures.

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.
