Support 'perf c2c record' for hybrid platform. On hybrid platform,
such as Alderlake, when executing 'perf c2c record', it actually calls:
record -W -d --phys-data --sample-cpu
-e {cpu_core/mem-loads-aux/,cpu_core/mem-loads,ldlat=30/}:P
-e cpu_atom/mem-loads,ldlat=30/P
-e cpu_core/mem-stores/P
-e cpu_atom/mem-stores/P

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.
