Hi,

looks like this warning came in with
af73e4d9506d3b797509f3c030e7dcd554f7d9c4 and fires in the

# CONFIG_HUGETLB_PAGE is not set

case because

	struct hstate *hs = hstate_sizelog((shmflg >> SHM_HUGE_SHIFT)
                                        & SHM_HUGE_MASK);

becomes

	struct hstate *hs = ((void *)0)

due to

#define hstate_sizelog(s) NULL

Hmmm, I don't have a quick solution off the top of my head from staring
at the code.
