- AMD uncore driver:
Replace the open coded sanity check with the core variant, which
provides the correct error code and also leaves a hint in dmesg
- tools:
- Fix the stdio input handling with glibc versions >= 2.28
- Unbreak the futex-wake benchmark which was reduced to 0 test threads
due to the conversion to cpumaps
- Initialize sigaction structs before invoking sys_sigactio()
- Plug the mapfile memory leak in perf jevents
- Fix off by one relative directory includes
- Fix an undefined string comparison in perf diff

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.
