For reference, here's what GRKERNSEC_HIDESYM looks like in grsecurity.
It's quite a sledgehammer, but it does help to point out at least the
minimum number of things that need fixing.

And, more directly related to this thread, kallsyms hiding is implemented
in s_show instead of via DAC:

/* Some debugging symbols have no name. Ignore them. */
if (!iter->name[0])

Here's the rest, manually extracted, untested, etc...
