The metrics "LLC Load Hitm" contains two items: one is "local Hitm" and another is "remote Hitm". "local Hitm" means: L3 HIT and was serviced by another processor core with a cross core snoop where modified copies were found; it's no doubt that "local Hitm" belongs to LLC access. But for "remote Hitm", based on the code in util/mem-events, it's the event for remote cache HIT and was serviced by another processor core with modified copies. Thus the remote Hitm is a remote cache's hit and actually it's LLC load miss. Now the display format gives users the impression that "local Hitm" and "remote Hitm" both belong to the LLC load, but this is not the fact as described. This patch changes the header from "LLC Load Hitm" to "Load Hitm", this can avoid the give the wrong impression that all Hitm belong to LLC.

README
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.
