+ # 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.
