Add new __init_task_data macro to be used in arch init_task.c files.
This patch is preparation for replacing most ".data.init_task" in the kernel with macros, so that the section name can later be changed without having to touch a lot of the kernel. The long-term goal here is to be able to change the kernel's magic section names to those that are compatible with -ffunction-sections -fdata-sections. This requires renaming all magic sections with names of the form ".data.foo". Signed-off-by: Tim Abbott <tabbott@ksplice.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
