Implement the CPU vulnerabilty show functions for meltdown, spectre_v1 and spectre_v2 on Alpha. Tests on XP1000 (EV67/667MHz) and ES45 (EV68CB/1.25GHz) show them to be vulnerable to Meltdown and Spectre V1. In the case of Meltdown I saw a 1 to 2% success rate in reading bytes on the XP1000 and 50 to 60% success rate on the ES45. (This compares to 99.97% success reported for Intel CPUs.) Report EV6 and later CPUs as vulnerable. Tests on PWS600au (EV56/600MHz) for Spectre V1 attack were unsuccessful (though I did not try particularly hard) so mark EV4 through to EV56 as not vulnerable.

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.
