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.

- Show expected versus obtained values in bp_signal test.

tools ui popup: Allow returning hotkeys

With this patch if an optional pointer is passed to ui__popup_menu()
then when any key that is not being handled (ENTER, ESC, etc) is typed,
it'll record that key in the pointer and return, allowing for hotkey
processing on the caller.

If NULL is passed, no change in logic, unhandled keys continue to be
ignored.

"Kernel side changes:

- Improved kbprobes robustness

- Intel PEBS support for PT hardware tracing

- Other Intel PT improvements: high order pages memory footprint
reduction and various related cleanups

- Misc cleanups

The perf tooling side has been very busy in this cycle, with over 300
commits. This is an incomplete high-level summary of the many
improvements done by over 30 developers:

- Lots of updates to the following tools:

'perf c2c'
'perf config'
'perf record'

- Updates to libperf and libtraceevent, and a consolidation of the
proliferation of x86 instruction decoder libraries.

- Vendor event updates for Intel and PowerPC CPUs,

- Updates to hardware tracing tooling for ARM and Intel CPUs,

- ... and lots of other changes and cleanups - see the shortlog and
Git log for details"

Sometimes we want just to print a message on the center of the screen,

collected before sorting and showing them.

Also expose __ui__info_window() as an optimization for cases where such
message is to be printed while holding the ui lock.
