Emulating TLBI VMALLS12E1* results in tearing down all the shadow S2 PTs that match the current VMID, since our shadow S2s are just some form of SW-managed TLBs. That teardown itself results in a full TLB invalidation for both S1 and S2. This can result in over-invalidation if two vcpus use the same VMID to tag private S2 PTs, but this is still correct from an architecture perspective.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
