[patch] ip27's _flush_cache_all uninitialized

[Andrew Clausen <clausen@melbourne.sgi.com>]

Hi all,

_flush_cache_all() and ___flush_cache_all() were uninitialized
(i.e. NULL).  Someone probably assumed (incorrectly) that this
was ok, since flush_cache_all() doesn't use _flush_cache_all()
(or so they thought...).

End result: anything that called flush_cache_all() (a macro)
tried to call a function at 0x0, and died.  This includes vmalloc().

I'm not sure what the best solution is, but this makes things work:
