Subject: [PATCH v3 00/16] x86,objtool: Optimize !RETPOLINE

Hi, another week, another update :-)

Respin of the !RETPOLINE optimization patches.

Boris, the first 3 should probably go into tip/x86/core, it's an ungodly tangle
since it relies on the insn decoder patches in tip/x86/core, the NOP patches in
tip/x86/cpu and the alternative patches in tip/x86/alternatives.

Just to make life easy I'd suggest merging everything in x86/core and
forgetting about the other topic branches (that's what I ended up doing locally).

The remaining 13 patches depend on the first 3 as well as on the work in
tip/objtool/core, just to make life more interesting still ;-)

All except the last 4 patches should be fairly uncontroversial (I hope...).

There's a fair number of new patches and another few have been completely
rewritten, but it all seems to work nicely.
