Pull RAS updates from Ingo Molnar:
"Boris is on vacation so I'm sending the RAS bits this time. The main
changes were:
- Various RAS/CEC improvements and fixes by Borislav Petkov:
- error insertion fixes
- offlining latency fix
- memory leak fix
- additional sanity checks
- cleanups
- debug output improvements
- More SMCA enhancements by Yazen Ghannam:
- make banks truly per-CPU which they are in the hardware
- don't over-cache certain registers
- make the number of MCA banks per-CPU variable
The long term goal with these changes is to support future
heterogenous SMCA extensions.
- Misc fixes and improvements"

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.
