Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs
when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes
on most platfoms (some reserve PAGE_SIZE for initramfs).

This patch fixes the kernel entry point address of vmlinux.
The m32r kernel entry address is 0x08002000 (physical).
But, so far, the ENTRY point written in vmlinux.lds.S was not point
the correct kernel entry address.

This fix also remedies the following GDB error message (of gdb-6.4 or after)
at the first operation of kernel debugging:
"Previous frame identical to this frame (corrupt stack?)".

Add a vmlinux.lds.h helper macro for defining the eight-level initcall table,
teach all the architectures to use it.
This is a prerequisite for a patch which performs initcall synchronisation for
multithreaded-probing.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
