DMI entries are arranged in memory back to back with no alignment
guarantees. This means that the struct dmi_header passed to callbacks
from dmi_walk() itself isn't byte aligned.  This causes problems on
architectures that expect aligned data, such as IA64.

The dmi-sysfs patchset introduced structure member accesses through this
passed in dmi_header.  Fix this by memcpy()ing the structures to
temporary locations on stack when inspecting/copying them.
