Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
perf record:
Alexey Budankov:
- Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
mask size limitation of cpu_set_t type.
perf report/top TUI:
Arnaldo Carvalho de Melo:
- Make ENTER consistently present the pop up menu with and without call
chains, to eliminate confusion. The menu continues available at all times
use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
the call chains for a top level histogram entry and 'E' to expand all call
chains in all top level entries. Extra info about these options was added to
the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
to the main vmlinux entries, to avoid having to press enter and then select
"Zoom into the kernel DSO".
perf sched timehist:
David Ahern:
- Add support for filtering on CPU.
perf tests:
Arnaldo Carvalho de Melo:
- Show expected versus obtained values in bp_signal test.
libperf:
Jiri Olsa:
- Move to tools/lib/perf.
- Add man pages.
libapi:
Andrey Zhizhikin:
- Fix gcc9 stringop-truncation compilation error.
tools lib:
Vitaly Chikunov:
- Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.

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.
