[PATCH] have sgi-gru driver call fs_initcall() if statically linked

[Dean Nelson <dcn@sgi.com>]

If xpc.ko and gru.ko are both statically linked into the kernel, then
xpc_init() can get called before gru_init() and make a call to one of the
gru's exported functions before the gru has initialized itself. The end
result is a NULL dereference.
