#     kbuild: remove 'addtree' and 'flags' magic for header search paths
#     
#     The 'addtree' and 'flags' in scripts/Kbuild.include are so compilecated
#     and ugly.
#     
#     As I mentioned in [1], Kbuild should stop automatic prefixing of header
#     search path options.
#     
#     I fixed up (almost) all Makefiles in the kernel. Now 'addtree' and
#     'flags' have been removed.
#     
#     Kbuild still caters to add $(srctree)/$(src) and $(objtree)/$(obj)
#     to the header search path for O= building, but never touches extra
#     compiler options from ccflags-y etc.

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.
