[roll] Roll fuchsia [kernel][lockup] Don't deref an invalid shadow call stack pointer When generating a DAP backtrace for a locked up CPU, don't read the memory pointed to by the SCSP unless it's a kernel address and mapped. Pull the backtrace generation logic out of DumpRegistersAndBacktrace and into its own method GetBacktraceFromDapState so that it can be easily tested. Add test for GetBacktraceFromDapState.

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.
