Daniel Borkmann a6c39de76d bpf, selftests: Add test cases for pointer alu from multiple paths 
Add several test cases for checking update_alu_sanitation_state() under
multiple paths:

  # ./test_verifier
  [...]
  #1061/u map access: known scalar += value_ptr unknown vs const OK
  #1061/p map access: known scalar += value_ptr unknown vs const OK
  #1062/u map access: known scalar += value_ptr const vs unknown OK
  #1062/p map access: known scalar += value_ptr const vs unknown OK
  #1063/u map access: known scalar += value_ptr const vs const (ne) OK
  #1063/p map access: known scalar += value_ptr const vs const (ne) OK
  #1064/u map access: known scalar += value_ptr const vs const (eq) OK
  #1064/p map access: known scalar += value_ptr const vs const (eq) OK
  #1065/u map access: known scalar += value_ptr unknown vs unknown (eq) OK
  #1065/p map access: known scalar += value_ptr unknown vs unknown (eq) OK
  #1066/u map access: known scalar += value_ptr unknown vs unknown (lt) OK
  #1066/p map access: known scalar += value_ptr unknown vs unknown (lt) OK
  #1067/u map access: known scalar += value_ptr unknown vs unknown (gt) OK

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.
