mmc_init_queue only initializes the scatterlists with sg_init_table()

To be able to do this, I need to intercept PTRACE_TRACEME and
PTRACE_ATTACH, as well as PTRACE_DETACH and thread exit. The latter
two can be handled by existing hooks.

Assigning -1 to a u32 member isn't a very nice example. What does it

Oh, and we definitely need a way to report errors. Looks like the
existing drivers want this as well -- I couldn't help but notice this
in the iop-adma driver:
static irqreturn_t
-free fun.
Fix it by incrementing the device's reference count twice for each
channel during registration.
