Samuel Holland <samuel.holland@sifive.com> says: This series (or equivalent) is a prerequisite for both user-mode pointer masking and CFI support, as both of those are per-thread features and are controlled by fields in the envcfg CSR. These patches are based on v1 of the pointer masking series[1], with significant input from both Deepak and Andrew.

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 reStructuredText 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.
