Linux kernel source tree
d8bd48e3f0
With ARMv8.4-NV, registers that can be directly accessed in memory by the guest have to live at architected offsets in a special page. Let's annotate the sysreg enum to reflect the offset at which they are in this page, whith a little twist: If running on HW that doesn't have the ARMv8.4-NV feature, or even a VM that doesn't use NV, we store all the system registers in the usual sys_regs array. The only difference with the pre-8.4 situation is that VNCR-capable registers are at a "similar" offset as in the VNCR page (we can compute the actual offset at compile time), and that the sys_regs array is both bigger and sparse.

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.
