Andrii Nakryiko 3caa7d2e2e Merge branch 'libbpf: Add syscall-specific variant of BPF_KPROBE'
Hengqi Chen says:

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

Add new macro BPF_KPROBE_SYSCALL, which provides easy access to syscall
input arguments. See [0] and [1] for background.

  [0]: https://github.com/libbpf/libbpf-bootstrap/issues/57
  [1]: https://github.com/libbpf/libbpf/issues/425

v2->v3:
  - Use PT_REGS_SYSCALL_REGS
  - Move selftest to progs/bpf_syscall_macro.c

v1->v2:
  - Use PT_REGS_PARM2_CORE_SYSCALL instead
====================

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.
