Andrii Nakryiko 57385ae31f selftests/bpf: Make perf_buffer selftests work on 4.9 kernel again 
Recent change to use tp/syscalls/sys_enter_nanosleep for perf_buffer
selftests causes this selftest to fail on 4.9 kernel in libbpf CI ([0]):

  libbpf: prog 'handle_sys_enter': failed to attach to perf_event FD 6: Invalid argument
  libbpf: prog 'handle_sys_enter': failed to attach to tracepoint 'syscalls/sys_enter_nanosleep': Invalid argument

It's not exactly clear why, because perf_event itself is created for
this tracepoint, but I can't even compile 4.9 kernel locally, so it's
hard to figure this out. If anyone has better luck and would like to
help investigating this, I'd really appreciate this.

For now, unblock CI by switching back to raw_syscalls/sys_enter, but reduce
amount of unnecessary samples emitted by filter by process ID. Use
explicit ARRAY map for that to make it work on 4.9 as well, because
global data isn't yet supported there.

README 

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.
