Get rid of multiple definitions of append_elf_note() & final_note()

Also, define Elf_Word and use it instead of generic u32 or the more
specific Elf64_Word.

Changes from v3:
* Dropped hard-coded values and used DIV_ROUND_UP().

Changes from v2:
* Added a definition for Elf_Word.
* Used IA64 version of append_elf_note() and final_note() functions.

Do the powerpc patches later in the series actually depend on this one?
Or is this just an unrelated cleanup?

As it is I can't merge the series until we at least get an ack on this
from the ia64 folks.

If you can just split this out as a separate patch that would make it a
lot easier to get the rest merged.


Hi Michael,

append_elf_note() & final_note() functions were defined statically at three different places,
arch/powerpc/kernel/fadump.c being one of them. With my changes, I would need to add
a fourth static definition if I ignore this cleanup. So, I preferred to clean this up...

Let me ping IA64 folks one last time. Will do a respin without the cleanup if I don't get
any response from them by end of this week..

Thanks
Hari
