Currently each sub-architecture has its own implementation if init_freemem().
There is two different cases that the various implementations deal with.
They either free the init memory, or they don't. We only need a single instance
to cover all cases.
The non-MMU version did some page alignment twidling, but this is not
neccessary. The current linker script enforces page alignment. It also
checked for CONFIG_RAMKERNEL, but this also is not necessary, the linker
script always keeps the init sections in RAM.
The MMU ColdFire version of free_initmem() was empty. There is no reason it
can't carry out the freeing of the init memory. So it is now changed and
tested to do this.
For the other MMU cases the code is the same. For the general Motorola MMU
case we free the init memory. For the SUN3 case we do nothing (though I
think it could safely free the init memory as well).

free_area_init_node() gets passed in the node id as well as the node
descriptor. This is redundant as the function can trivially get the node
descriptor itself by means of NODE_DATA() and the node's id.
I checked all the users and NODE_DATA() seems to be usable everywhere
from where this function is called.

As noted by Akinobu Mita in patch b1fceac2b9,
alloc_bootmem and related functions never return NULL and always return a
zeroed region of memory. Thus a NULL test or memset after calls to these
functions is unnecessary.
This was fixed using the following semantic patch.

General compile fixes for 2.6.16 for sun3, and some updates to make the new
bootloader work correctly. Tested on 3/50, 3/60, 3/80.

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!
