[roll] Roll fuchsia [kernel][x86] Spectre V2/RETBLEED: Don't enable STIBP if SMT isn't present STIBP is 'single-thread indirect branch predictor' mode, a mode that prevents code running on one hyperthread from influencing branch predictions on its paired hyperthread. On some processors, fully mitigating Spectre V2 or RETBLEED requires STIBP to be set. STIBP is not required if hyperthreading/SMT isn't present or enabled. Don't bother enabling STIBP for Spectre V2 or RETBLEED mitigations if hyperthreading is not present or enabled; this avoids unnecessary performance impacts from STIBP.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance via the IRC channel #fuchsia on Freenode.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
