#     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.
#     
#     Instead, in-kernel Makefiles should explicitly add $(srctree)/ to
#     the search paths in the srctree.
#     
#     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.
#     
#     Going forward, in-kernel Makefiles should explicitly specify
#     $(srctree)/ if extra search paths are needed.
#     
#      Example)    ccflags-y += -I $(srctree)/foo/bar
#     
#     You do not have to change external module Makefiles because $(src)
#     is already an absolute path for external modules.
#     
#      Example)    ccflags-y += -I $(src)/foo/bar

WARNING: vmlinux.o(.text+0x40e): 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.

WARNING: vmlinux.o (.PPC.EMB.apuinfo): unexpected non-allocatable section.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
