We recently added a INIT_TASK(align) in include/asm-generic/vmlinux.lds.h, but there is already a macro INIT_TASK in include/linux/init_task.h, which is quite confusing. We should switch the macro in the linker script to INIT_TASK_DATA. (Sorry that I missed this in reviewing the patch). Since the macros are new, there is only one user of the INIT_TASK in vmlinux.lds.h, arch/mn10300/kernel/vmlinux.lds.S. However, we are currently using INIT_TASK_DATA for laying down an entire .data.init_task section. So rename that to INIT_TASK_DATA_SECTION. I would be worried about changing the meaning of INIT_TASK_DATA, but the old INIT_TASK_DATA implementation had no users, and in fact if anyone had tried to use it, it would have failed to compile because it didn't pass the alignment to the old INIT_TASK.
