Remove the function kgdb_post_primary_code() that is not used anywhere.

This was partially found by using a static code analysis program called cppcheck.

<title>all arches, signal: move restart_block to struct task_struct</title>

<id>f56141e3e2d9aabf7e6b89680ab572c2cdbb2a24</id>
<content type='text'>
If an attacker can cause a controlled kernel stack overflow, overwriting
the restart block is a very juicy exploit target.  This is because the
restart_block is held in the same memory allocation as the kernel stack.

Moving the restart block to struct task_struct prevents this exploit by
making the restart_block harder to locate.

Note that there are other fields in thread_info that are also easy
targets, at least on some architectures.

It's also a decent simplification, since the restart code is more or less
identical on all architectures.
