The mysterious comment "We only want the cr8 intercept bits of L1"
dates back to basically the introduction of nested SVM, back when
the handling of "less typical" hypervisors was very haphazard.
With the development of kvm-unit-tests for interrupt handling,
the same code grew another vmcb_clr_intercept for the interrupt
window (VINTR) vmexit, this time with a comment that is at least
decent.
It turns out however that the same comment applies to the CR8 write
intercept, which is also a "recheck if an interrupt should be
injected" intercept. The CR8 read intercept instead has not
been used by KVM for 14 years (commit

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.
