perf tools: Allow using PERF_RECORD_MMAP2 to synthesize the kernel modules maps
Jiri Olsa authored

Allow using PERF_RECORD_MMAP2 to synthesize the kernel modules maps so
that we can use PERF_RECORD_MMAP2 to encode the kernel modules build ids
in the following csets.

It's enabled by a new symbol_conf.buildid_mmap2 bool field, which will
be switchable in following changes.

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.
