Subject: [PATCH 0/5] lkdtm: add usercopy and rodata, fix atomic

This adds several new tests to lkdtm.

To test non-executability of .rodata, lkdtm's build method shifted
around a bit requiring a source file rename. But after some objcopy
magic, there is now an architecture-agnostic way to write functions
into .rodata.

The atomic under/overflow test was split so that each case could be
individually tested.

The biggest addition are the usercopy tests (in preparation for
This tests both directions (copy_to_from, copy_from_user) of the
three error conditions that are checked for: wrong object size,
wrong stack frame, and wrong object markings.

Unless anyone has blocking comments, I'll send a pull to Greg
for this to land in -next soon.
