Linux kernel source tree
1d6fea7663
A common idiom in the KVM code is to check if we are currently dealing with a "nested" context, defined as having NV enabled, but being in the EL1&0 translation regime. This is usually expressed as: if (vcpu_has_nv(vcpu) && !is_hyp_ctxt(vcpu) ... ) which is a mouthful and a bit hard to read, specially when followed by additional conditions. Introduce a new helper that encapsulate these two terms, allowing the above to be written as if (is_nested_context(vcpu) ... ) which is both shorter and easier to read, and makes more obvious the potential for simplification on some code paths.

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.
