In the previous discussion (see the Link tag), Ard pointed out that arm/arm64/kernel/head.o does not need any special treatment - the only piece that must appear right at the start of the binary image is the image header which is emitted into .head.text. The linker script does the right thing to do. The build system does not need to manipulate the link order of head.o.

# Head objects
|
|
#
|
|
# The objects listed here are placed at the head of vmlinux. A typical use-case
|
|
# is an object that contains the entry point. This is kept for compatibility
|
|
# with head-y, which Kbuild used to support.
|
|
#
|
|
# A counter approach is to control the section placement by the linker script.
|
|
# The code marked as __HEAD goes into the ".head.text" section, which is placed
|
|
# before the normal ".text" section.
|
|
#
|
|
# If you can achieve the correct code ordering by linker script, please delete
|
|
# the entry from this file.
