[roll] Roll fuchsia [kernel][percpu] Add optimized percpu::GetCurrent Add a percpu* field to the low-level arch-specific percpu structs so we can get the current CPU's percpu struct without having to perform an array lookup using the current CPU number. Add arch_get_percpu and arch_setup_percpu. Add static method percpu::GetCurrent() that uses arch_get_percpu. arch_get_percpu will allow a future CPU to break a dependency cycle and inline parts of lockup_detector.

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.
