cool! Please Cc: lkml and Harvey as well so that there's less overlap in 
unification work - Harvey spent quite some time unifying and cleaning up 
the kprobes code during the past week.

So i think we could/should use Harvey's latest series as a base, those 
are pretty finegrained already. Note that they break 64-bit kprobes 
though, with such a config:

 CONFIG_KPROBES=y
 CONFIG_NET_TCPPROBE=y

so it crashes with an int3 in the TCP code. It's probably some trivial 
typo somewhere, as 32-bit works fine.

the coordinates for x86.git#mm can be found below - that tree already 
includes Harvey's latest kprobes series. I'll try to bisect the 64-bit 
breakage now.

(do subsequent pulls via "git-pull --force", as we frequently rebase the
git tree. NOTE: this might override your own local changes, so do this
only if you dont mind about losing thse changes in that tree.)
