Oliver Upton 6db7af0d5b KVM: arm64: Handle ID register reads using the VM-wide values
Everything is in place now to use the generic ID register
infrastructure. Use the VM-wide values to service ID register reads.
The ID registers are invariant after the VM has started, so there is no
need for locking in that case. This is rather desirable for VM live
migration, as the needless lock contention could prolong the VM blackout
period.

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.
