Allmodconfig kernels produce a missing-prototypes warning:
arch/powerpc/platforms/ps3/gelic_udbg.c:239:6: error: no previous prototype for 'udbg_shutdown_ps3gelic' [-Werror=missing-prototypes]
Move the declaration from a local header to asm/ps3.h where it can be
seen from both the caller and the definition.

As pointed out by Arnd this is due to there being two symbols that
control the gelic_udbg.c code.
I don't see the need for PS3GELIC_UDBG, without PPC_EARLY_DEBUG_PS3GELIC
it just causes gelic_udbg.c to be built, but never called.
The diff below fixes the error AFAICS.
I can just fold it in if you're happy with that Arnd.

My first thought was: PPC_EARLY_DEBUG_PS3GELIC is meant as an early
debugging console, while PS3GELIC_UDBG can be used with xmon later,
but that does not seem to be the case.

So your changes on top LGTM.
