* kvm-arm64/ctr-el0: : Support for user changes to CTR_EL0, courtesy of Sebastian Ott : : Allow userspace to change the guest-visible value of CTR_EL0 for a VM, : so long as the requested value represents a subset of features supported : by hardware. In other words, prevent the VMM from over-promising the : capabilities of hardware. : : Make this happen by fitting CTR_EL0 into the existing infrastructure for : feature ID registers.

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.
