Pull RAS fixes from Thomas Gleixner:
"Two fixes for the AMD MCE driver:
- Populate the per CPU MCA bank descriptor pointer only after it has
been completely set up to prevent a use-after-free in case that one
of the subsequent initialization step fails
- Implement a proper release function for the sysfs entries of MCA
threshold controls instead of freeing the memory right in the CPU
teardown code, which leads to another use-after-free when the
associated sysfs file is opened and accessed"

============
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.
