Move the handling of GLOBAL_CTRL, GLOBAL_STATUS, and GLOBAL_OVF_CTRL, a.k.a. GLOBAL_STATUS_RESET, from Intel PMU code to generic x86 PMU code. AMD PerfMonV2 defines three registers that have the same semantics as Intel's variants, just with different names and indices. Conveniently, since KVM virtualizes GLOBAL_CTRL on Intel only for PMU v2 and above, and AMD's version shows up in v2, KVM can use common code for the existence check as well.

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.
