Paul Chaignon says:
====================
Currently, helpers that expect ARG_PTR_TO_MAP_KEY and ARG_PTR_TO_MAP_VALUE
can only access stack and packet memory. This patchset allows these
helpers to directly access map values by passing registers of type
PTR_TO_MAP_VALUE.
The first patch changes the verifier; the second adds new test cases.
The first three versions of this patchset were sent on the iovisor-dev
mailing list only.
Changelogs:
Changes in v5:
- Refactor using check_helper_mem_access.
Changes in v4:
- Rebase.
Changes in v3:
- Bug fixes.
- Negative test cases.
Changes in v2:
- Additional test cases for adjusted maps.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
