[ Upstream commit f2913d006fcdb61719635e093d1b5dd0dafecac7 ]
I don't think we can actually die() without a regs pointer, but the
compiler was warning about a NULL check after a dereference. It seems
prudent to just avoid the possibly-NULL dereference, given that when
die()ing the system is already toast so who knows how we got there.
