Subject: [RESEND PATCH] Convert IA64 sysctl to generic

Hi,

This came out ARC Port's review by Arnd where he suggested using the existing
sysctl knobs in parisc and/or ia64 for runtime controlling unaligned access
emulation.

Turns out that ARC port needs bit of both.

The common sysctl knobs are now #ifdef based on init/Kconfig options which
the corresponding arches now select in their Kconfigs.
No other arch code is touched (although code has not been compile tested).

If this patch is ACKable, I would request you to please take this patch
via your arch tree - to avoid any merge-hassles and other interdependencies
later.

P.S. I've deliberately NOT added the new items at the end of arch/*/Kconfig,
to avoid any merge conflicts going further - anyhow both the ia64/parisc
Kconfigs are not sorted either.

Thx,
-Vineet
