Merge branch 'bpf_cubic'

Martin KaFai Lau says:

====================
This set adds bpf_cubic.c example.  It was separated from the
earlier BPF STRUCT_OPS series.  Some highlights since the
last post:

1. It is based on EricD recent fixes to the kernel tcp_cubic. [1]
2. The bpf jiffies reading helper is inlined by the verifier.
   Different from the earlier version, it only reads jiffies alone
   and does not do usecs/jiffies conversion.
3. The bpf .kconfig map is used to read CONFIG_HZ.

v3:
- Remove __weak from CONFIG_HZ in patch 3. (Andrii)

v2:
- Move inlining to fixup_bpf_calls() in patch 1. (Daniel)
- It is inlined for 64 BITS_PER_LONG and jit_requested
  as the map_gen_lookup().  Other cases could be
  considered together with map_gen_lookup() if needed.
- Use usec resolution in bictcp_update() calculation in patch 3.
  usecs_to_jiffies() is then removed().  (Eric)

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.
