Rob Herring (Arm) 1ae981c91d perf: arm_pmuv3: Call kvm_vcpu_pmu_resync_el0() before enabling counters
[ Upstream commit 04bd15c4cbc3f7bd2399d1baab958c5e738dbfc9 ]

Counting events related to setup of the PMU is not desired, but
kvm_vcpu_pmu_resync_el0() is called just after the PMU counters have
been enabled. Move the call to before enabling the counters.

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.
