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.

Fix the MN10300 vmlinux ldscript. It needs to use various macros from
asm-generic/vmlinux.lds.h to correctly include all that it needs to.

This has the consequence of changing the section name use for head
code from ".text.head" to ".head.text". Since this commit changes all
users in the architecture, this change should be harmless.

Include the linux/page.h header into the MN10300 kernel linker script thus
allowing us to use PAGE_SIZE macro instead of a numeric constant.
Also use the PERCPU macro instead of an explicit section definition.

Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.
This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305. The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
