#     kbuild: remove wrong documentation about mandatory-y
#     
#     This sentence does not make sense in the section about mandatory-y.
#     
#     This seems to be a copy-paste mistake of commit fcc8487d477a ("uapi:
#     export all headers under uapi directories").
#     
#     The correct description would be "The convention is to list one
#     mandatory-y per line ...".
#     
#     I just removed it instead of fixing it. If such information is needed,
#     it could be commented in include/asm-generic/Kbuild and
#     include/uapi/asm-generic/Kbuild.

WARNING: vmlinux.o(.text+0x2fc8): 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.
