Ingo Molnar a89d0c2acf perf/urgent fixes and improvements:
perf stat:
 
 . Add --interval-clear option, to provide a 'watch' like printing (Jiri Olsa)
 
 . Fix metric column header display alignment (Jiri Olsa)
 
 . Improve error messages for default attributes, providing better output
   for error in command lines such as:
 
   $ perf stat -T
   Cannot set up transaction events
   event syntax error: '..cycles,cpu/cycles-t/,cpu/tx-start/,cpu/el-start/,cpu/cycles-ct/}'
                                     \___ unknown term
 
   Where the "event syntax error" line now appears (Jiri Olsa)
 
 perf script:
 
 . Show hw-cache events too (Seeteena Thoufeek)
 
 perf c2c:
 
 . Fix data dependency problem in layout of 'struct c2c_hist_entry', where
   its member 'struct hist_entry' must be at the end because it has a ZLA
   as its last member, that gets space when handling callchains (Jiri Olsa)
 
 Core:
 
 - We cannot assume that a 'struct perf_evsel'  is to be obtained from a
   container_of operation on a 'struct hists' as there are tools, such as
   'perf c2c' that uses 'struct hist' instances without having them in
   container structs that also have 'struct perf_evsel' in a particular
   layout, so provide a different way of figuring out if a 'struct hists'
   and 'struct hist_entry' have callchains (Arnaldo Carvalho de Melo)
 
 - Fix error index in the PMU event parser, so that error messages can
   point to the problematic token (Jiri Olsa)

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
