Architecture features that are conditionally visible to the guest will require run-time checks in the ID register accessor functions. In particular, read_id_reg() will need to perform checks in order to generate the correct emulated value for certain ID register fields such as ID_AA64PFR0_EL1.SVE for example. This patch propagates vcpu into read_id_reg() so that future patches can add run-time checks on the guest configuration here. For now, there is no functional change.

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.
