I'm seeing some unaligned references from this function
on ia64.  Code is loading a 2-byte value from an odd
address. We are dereferencing "dh", so looking at the
dmi_header definition, I'd have thought that we must
be touching dh->handle:

struct dmi_header {
        u8 type;
        u8 length;
        u16 handle;
};

I don't see any code in this function that does this,
so I assume there is some inlining or macro stuff
happening.
