Libbpf compiles and runs subset of selftests on each PR in its Github mirror repository. To allow still building up-to-date selftests against outdated kernel images, add back BPF_F_CURRENT_CPU definitions back. N.B. BCC's runqslower version ([0]) doesn't need BPF_F_CURRENT_CPU due to use of locally checked in vmlinux.h, generated against kernel with1aae4bdd78("bpf: Switch BPF UAPI #define constants used from BPF program side to enums") applied.

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.
