Thi patch adds PMC events for AMD Family 17 CPUs as defined in [1]. It
covers events described in section: 2.1.13. Regex pattern in mapfile.csv
covers all CPUs of the family.

The perf tools cannot find the proper event list for the Cascadelake
server. Because the Cascadelake server and the Skylake server have the
same CPU model number, which are used by the perf tools to find the
event list.
The stepping for Skylake server is up to 4.
The stepping for Cascadelake server starts from 5.
The stepping can be used to distinguish between them.
The stepping is added in get_cpuid_str().
The stepping information for Skylake server is updated in mapfile.csv.
A x86 specific strcmp_cpuid_cmp() function is added to handle two CPUID
formats in mapfile.csv, "vendor-family-model-stepping" and
"vendor-family-model":
- If a cpuid-regular-expression from the mapfile.csv using the new
stepping format, a cpuid-string generated on the machine must include
stepping. Otherwise, it is a mismatch.
- If the cpuid-regular-expression using the old non-stepping format,
the stepping in the cpuid-string will be ignored.
The script, using environment string "PERF_CPUID" without stepping on
Skylake server, will be broken. If so, users must fix their scripts.
Committer notes:
Fixed this build error on centos:6 and debian:7:
arch/x86/util/header.c: In function 'is_full_cpuid':

identification for mapfile.csv
The powerpc cpuid information includes chip revision information.
Changes between chip revisions are usually minor bug fixes and usually
do not affect the operation of the performance monitoring hardware.
The original mapfile.csv matching requires enumerating every possible
cpuid string. When a new minor chip revision is produced a new entry
has to be added to the mapfile.csv and the code recompiled to allow perf
to have the implementation specific perf events for this new minor
revision. For users of various distibutions of Linux having to wait for
a new release of the kernel's perf tool to be built with these trivial
patches is inconvenient.
Using regular expressions rather than exactly string matching of the
entire cpuid string allows developers to write mapfile.csv files that do
not require patches and recompiles for each of these minor version
changes. If special cases need to be made for some particular versions,
they can be placed earlier in the mapfile.csv file before the more
general matches.
