Expose FEAT_LPA2 as a capability so that we can take advantage of alternatives patching in the hypervisor. Although FEAT_LPA2 presence is advertised separately for stage1 and stage2, the expectation is that in practice both stages will either support or not support it. Therefore, we combine both into a single capability, allowing us to simplify the implementation. KVM requires support in both stages in order to use LPA2 since the same library is used for hyp stage 1 and guest stage 2 pgtables.

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 Restructured Text 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.
