Subject[PATCH v4 00/14] various dynamic_debug patches
This started as an experiment to see how hard it would be to change
the four pointers in struct _ddebug into relative offsets, a la
pr_debug site (and thus exactly making up for the extra space used by
the introduction of jump labels in 9049fc74). I stumbled on a few
things that are probably worth fixing regardless of whether that goal
is deemed worthwhile.

Back at v3 (in November), I redid the implementation on top of the
fancy new asm-macros stuff. Luckily enough, v3 didn't get picked up,
since the asm-macros were backed out again. I still want to do the
relative-pointers thing eventually, but we're close to the merge
window opening, so here's just most of the "incidental" patches, some
of which also serve as preparation for the relative pointers.

I'm not sure how long an Ack/Reviewed-by is good for, but OTOH it also
feels rude to just drop them on the floor. I've kept those tags since
the rebasing to current master went completely smooth.

Andrew, please pick these up for soaking in -next.
