Subject: [PATCH 00/15] x86 cleanups and static_call()

Hi!

Now that all the x86_64 int3_emulate_call() stuff is upstream, here are the
i386 patches and all the rest of the cleanups that resulted from that
discussion.

And I figured I should have a go at making that static_call() thing working now
that we have the prerequisites sorted.  This is mostly a combination of the v2
and v3 static_call() patches done on top of an 'enhanced' text_poke_bp().

I wrote a little self-test and added Steve's ftrace convertion on top for
testing, and suspicously I've not had it explode, so I'm sure this is going to
set all your computers on fire.

Enjoy!
