get_vcpu_ptr is an assembly accessor for the percpu value kvm_host_data->host_ctxt.__hyp_running_vcpu. kern_hyp_va only applies to nVHE however __hyp_running_vcpu is always assigned a pointer that has already had kern_hyp_va applied in __kvm_vcpu_run_nvhe. kern_hyp_va is currently idempotent as it just masks and inserts the tag, but this could change in future and the second application is unnecessary.

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.
