Linus Torvalds 158405e888 - Get rid of a bunch of function pointers used in MCA land in favor 
of normal functions. This is in preparation of making the MCA code
 noinstr-aware
 
 - When the kernel copies data from user addresses and it encounters a
 machine check, a SIGBUS is sent to that process. Change this action to
 either an -EFAULT which is returned to the user or a short write, making
 the recovery action a lot more user-friendly

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.
