Merge v5.6-rc2 into drm-misc-next

Lyude needs some patches in 5.6-rc2 and we didn't bring drm-misc-next
forward yet, so it looks like a good occasion.

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf updates from Ingo Molnar:
"Kernel side changes:

- Ftrace is one of the last W^X violators (after this only KLP is
left). These patches move it over to the generic text_poke()
interface and thereby get rid of this oddity. This requires a
surprising amount of surgery, by Peter Zijlstra.

- x86/AMD PMUs: add support for 'Large Increment per Cycle Events' to
count certain types of events that have a special, quirky hw ABI
(by Kim Phillips)

- kprobes fixes by Masami Hiramatsu

Lots of tooling updates as well, the following subcommands were
updated: annotate/report/top, c2c, clang, record, report/top TUI,
sched timehist, tests; plus updates were done to the gtk ui, libperf,
headers and the parser"

Merge tag 'perf-core-for-mingo-5.6-20200106' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

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.

libperf: Add man pages

Change the man page generation to asciidoc, because it's easier to use
and has been more commonly used in related projects. Remove the current
rst pages.

Add 3 man pages to have a base for more additions:

libperf.3 - overall description
libperf-counting.7 - counting basics explained on simple example
libperf-sampling.7 - sampling basics explained on simple example

The plan is to add more man pages to cover the basic API.

The build generates html and man pages:

$ cd tools/lib/perf/Documentation
$ make
ASCIIDOC libperf.xml
XMLTO libperf.3
ASCIIDOC libperf-counting.xml
XMLTO libperf-counting.7
ASCIIDOC libperf-sampling.xml
XMLTO libperf-sampling.7
ASCIIDOC libperf.html
ASCIIDOC libperf-counting.html
ASCIIDOC libperf-sampling.html

Add the following install targets:

install-man - man pages
install-html - html version of man pages
install-examples - examples mentioned in the man pages
