[roll] Roll fuchsia [x86][hypervisor] Invalidate EPT on unmap

Invalidates the EPT context when unmapping from EPT page tables. Due to
lack of tracking this is implemented as an IPI broadcast to all CPUs.
Without this invalidation it is possible for the user space VMM code to
either unmap from the vmar, or decommit from the backing VMOs, and then
the guest could keep using the stale EPT TLB entries to write to the
old pages, effectively causing arbitrary memory corruption.

Integration

This repository contains Fuchsia's Global Integration manifest files.

Making changes

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.

Obtaining the source

First install Jiri.

Next run:

$ jiri init
$ jiri import minimal https://fuchsia.googlesource.com/integration
$ jiri update

Third party

Third party projects should have their own subdirectory in ./third_party.
