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:
