Brings back the cheap dial()

In case you want to bypass the full dial + cs + dialstring parsing.
Poor-man's ftrace has more context

Will output whether we're in a process, IRQ, or ktask context.

Careful using this on certain devices in k/d/dev/, like acpi and console.  One
of the devs locks up if you try to print.

I usually turn off the 'print' bool in kdebug.c for booting, then turn it on
via 'kfunc toggle_print_func'.

To spatch the networking code, try something like:

$ for i in kern/src/net kern/drivers/net kern/drivers/dev/ether.c; do
	spatch --sp-file scripts/spatch/poor-ftrace.cocci  --in-place $i; done
