init: provide a generic free_initmem implementation
Patch series "provide a generic free_initmem implementation", v2.
Many architectures implement free_initmem() in exactly the same or very
similar way: they wrap the call to free_initmem_default() with sometimes
different 'poison' parameter.
These patches switch those architectures to use a generic implementation
that does free_initmem_default(POISON_FREE_INITMEM).
This was inspired by Christoph's patches for free_initrd_mem [1] and I
shamelessly copied changelog entries from his patches :)

This patch (of 2):
For most architectures free_initmem just a wrapper for the same
free_initmem_default(-1) call. Provide that as a generic implementation
marked __weak.
