Brian Gianforcaro 72f348a6cf Meta: Disable printing frame args when debugging the kernel with gdb
The function arguments almost always optimized away, so you never get
much value out of showing these in the default back trace view, it just
adds a bunch of extra stuff that you need to visual wade through.
So lets disable showing them.
