perf kvm tool defines its own cached list which is managed with RB tree, histograms also provide RB tree to manage data entries. Since now we have introduced histograms in the tool, it's not necessary to use the self defined list and we can directly use histograms list to manage KVM events. This patch changes to use histograms list to track KVM events, and it invokes the common function hists__output_resort_cb() to sort result, this also give us flexibility to extend more sorting key words easily. After histograms list supported, the cached list is redundant so remove the relevant code for it. Committer notes: kvm_hists__reinit() is only used by functions enclosed in: #if defined(HAVE_KVM_STAT_SUPPORT) && defined(HAVE_LIBTRACEEVENT) So do it with this new function 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.
