Linux kernel source tree

We currently check for HCR_EL2.NV being set to decide whether we need to repaint PSTATE.M to say EL2 instead of EL1 on exit. However, this isn't correct when L2 is itself a hypervisor, and that L1 as set its own HCR_EL2.NV. That's because we "flatten" the state and inherit parts of the guest's own setup. In that case, we shouldn't adjust PSTATE.M, as this is really EL1 for both us and the guest. Instead of trying to try and work out how we ended-up with HCR_EL2.NV being set by introspecting both the host and guest states, use a per-CPU flag to remember the context (HYP or not), and use that information to decide whether PSTATE needs tweaking.

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.
