#     kbuild: remove head-y syntax
#     
#     Kbuild puts the objects listed in head-y at the head of vmlinux.
#     Conventionally, we do this for head*.S, which contains the kernel entry
#     point.
#     
#     A counter approach is to control the section order by the linker script.
#     Actually, the code marked as __HEAD goes into the ".head.text" section,
#     which is placed before the normal ".text" section.
#     
#     I do not know if both of them are needed. From the build system
#     perspective, head-y is not mandatory. If you can achieve the proper code
#     placement by the linker script only, it would be cleaner.
#     
#     I collected the current head-y objects into head-object-list.txt. It is
#     a whitelist. My hope is it will be reduced in the long run.
