When handling userspace MSR filter updates, recompute interception for possible passthrough MSRs if and only if KVM wants to disabled interception. If KVM wants to intercept accesses, i.e. the associated bit is set in vmx->shadow_msr_intercept, then there's no need to set the intercept again as KVM will intercept the MSR regardless of userspace's wants. No functional change intended, the call to vmx_enable_intercept_for_msr() really is just a gigantic nop.

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.
