Subject: [PATCH 2/3] constify struct kobj_type's default_attrs (against
-mm)
In the EDAC code, I took the opportunity to replace the explicit cast
initializer with a safer, cast-less mechanism (as used elsewhere),
which makes this patch somewhat larger than it would have been
otherwise.
Again, the patch doesn't change all instances where 'const' could have
been added as a result of the base structure changes, only where the
change has a real effect (the module loader doesn't enforce read-only
section attributes at present, so only built-in files matter).
