Subject: [PATCH 0/3] perf report: Add support to print a textual representation of IBS raw sample data

Hello Linux perf tools users and maintainers,

The first patch in this series prepares the perf tool to support
retrieving cpuid and pmu_mappings data when in report mode,
information that is needed to accurately decode IBS data.

The second patch adds a header file tools/arch/x86/include/asm/amd-ibs.h
from a separate kernel-side submittion [1].

The third patch allows the tool to print a textual representation
of the sample data recorded by IBS.
