[PATCH 0/2] jump label: update for .39

[Jason Baron <jbaron@redhat.com>]

Hi,

Re-fresh of updates against latest -tip tree.

I've tried to split this update up somewhat, but I've only succeeded to split
out the dynamic debug bits. The interface changes and re-write are quite
intertwined.

I believe this update should address all the comments from the previous posting
except for Mathieu's request for a section of jump label pointers that point to
the jump label structures (since the compiler might leave gaps in the jump label
structures). I've got a prototype patch to address this issue but its somewhat
invasive, and thus I'd like to leave it as a follow-up item. I have to date,
not seen this issue in practice.

thanks,

-Jason
