Alexei Starovoitov 7d8d535546 Merge branch 'libbpf: support non-mmap()'able data sections'
Andrii Nakryiko says:

====================

Make libbpf more conservative in using BPF_F_MMAPABLE flag with internal BPF
array maps that are backing global data sections. See patch #2 for full
description and justification.

Changes in this dataset support having bpf_spinlock, kptr, rb_tree nodes and
other "special" variables as global variables. Combining this with libbpf's
existing support for multiple custom .data.* sections allows BPF programs to
utilize multiple spinlock/rbtree_node/kptr variables in a pretty natural way
by just putting all such variables into separate data sections (and thus ARRAY
maps).

v1->v2:
  - address Stanislav's feedback, adds acks.

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.
