Pull perf updates from Ingo Molnar:
"The main kernel changes were:
- add support for Intel's "adaptive PEBS v4" - which embedds LBS data
in PEBS records and can thus batch up and reduce the IRQ (NMI) rate
significantly - reducing overhead and making call-graph profiling
less intrusive.
- add Intel CPU core and uncore support updates for Tremont, Icelake,
- extend the x86 PMU constraints scheduler with 'constraint ranges'
to better support Icelake hw constraints,
- make x86 call-chain support work better with CONFIG_FRAME_POINTER=y
- misc other changes
Tooling changes:
- updates to the main tools: 'perf record', 'perf trace', 'perf
stat'
- updated Intel and S/390 vendor events
- libtraceevent updates
- misc other updates and fixes"

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.
