Subject: [PATCH -tip v3 0/7] kprobes: x86: Cleanup jprobe implementation on x86

Hello,

Since we decided to remove jprobe from kernel last year,
its APIs are disabled and we worked on moving in-kernel
jprobe users to kprobes or trace-events. And now no jprobe
users are here anymore.

This is the 3rd version of the series for removing jprobe
from x86 and generic code. V2 is here;

 http://lkml.org/lkml/2018/3/12/558

Changes from v2 are;
 - [1/7] Imported from another series. Just a documentation
   fix.
 - [6/7] Imported from another series. Simplifying execution
   path modifying behavior.
 - [7/7] Modified based on [6/7], because it has done a half
   of changes what this patch does.

I am preparing other series which removes jprobe from
each arch. After all those patches are merged, I will remove
jprobes APIs and data structures, since changing those
definitions will break build on other archs.

Thank you,
