IA32_MCG_STATUS.RIPV indicates whether the return RIP value pushed onto the stack as part of machine check delivery is valid or not. Various drivers copied a code fragment that uses the RIPV bit to determine the severity of the error as either HW_EVENT_ERR_UNCORRECTED or HW_EVENT_ERR_FATAL, but this check is reversed (marking errors where RIPV is set as "FATAL"). Reverse the tests so that the error is marked fatal when RIPV is not set.

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.
