[roll] Roll fuchsia [kernel][hypervisor][arm64] Route SError exceptions to EL2 On ARM64, asynchronous SError (system error) exceptions are triggered external to the CPU, such as a memory access which has passed all the MMU checks but encounters an error on the memory bus. The Zircon kernel currently masks SErrors (https://fxbug.dev/72659, https://fxbug.dev/75834), but Linux guest kernels keep them unmasked. The result is that if host Zircon encounters an SError exception, it will remain pending until Zircon finally schedules a Linux guest, which will spuriously take the exception. This CL updates the hypervisor's EL2 config to route SErrors taken by guests to EL2. These are sent to the host Zircon kernel which prints an error message to the kernel log, and then resumes the guest.

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.
