Linux kernel source tree

For events that count data cache fills, some combinations of the unit mask bits are useful for counting fills from local caches, DRAM or any far sources. However, named events currently exist for PMCx044 (Any Data Cache Fills) only. Add similar events for the following base events. * PMCx043 (Demand Data Cache Fills) * PMCx059 (Software Prefetch Data Cache Fills) * PMCx05A (Hardware Prefetch Data Cache Fills) While at it, remove "ls_any_fills_from_sys.all_dram_io" since it is a duplicate of "ls_any_fills_from_sys.dram_io_all". Event descriptions can be found in Section 2.1.16.5.2 "Load/Store (LS) Events" of the Processor Programming Reference (PPR) for AMD Family 1Ah Model 02h Revision C1 Processors document available at the link below.

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 reStructuredText 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.
