The method to reset Architectural LBRs is different from previous model-specific LBR. Perf has to implement a different function. A function pointer is introduced for LBR reset. The enum of LBR_FORMAT_* is also moved to perf_event.h. Perf should initialize the corresponding functions at boot time, and avoid checking lbr_format at run time. The current 64-bit LBR reset function is set as default.

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.
