Linus Torvalds c813e8c9df Filter MSR writes from user-space by default, and print a syslog entry if 
they happen outside the allowed set of MSRs, which is a single one for now,
 MSR_IA32_ENERGY_PERF_BIAS.
 
 The plan is to eventually disable MSR writes by default (they can still be
 enabled via allow_writes=on).

README 

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.
