Yang Jihong 4f8ae962f0 perf kwork: Add irq kwork record support
Record interrupt events irq:irq_handler_entry & irq_handler_exit

Test cases:

 # perf kwork record -o perf_kwork.date -- sleep 1
  [ perf record: Woken up 0 times to write data ]
  [ perf record: Captured and wrote 0.556 MB perf_kwork.date ]
  #
  # perf evlist -i perf_kwork.date
  irq:irq_handler_entry
  irq:irq_handler_exit
  dummy:HG
  # Tip: use 'perf evlist --trace-fields' to show fields for tracepoint events

README

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.
