Consolidate all of the dynamic MSR bitmap adjustments into vmx_update_msr_bitmap_x2apic(), and rename the mode tracker to reflect that it is x2APIC specific. If KVM gains more cases of dynamic MSR pass-through, odds are very good that those new cases will be better off with their own logic, e.g. see Intel PT MSRs and MSR_IA32_SPEC_CTRL. Attempting to handle all updates in a common helper did more harm than good, as KVM ended up collecting a large number of useless "updates".

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.
