Linus Torvalds 9c5d00cb7b perf tools fixes for v6.6: 2nd batch
- Fix regression in reading scale and unit files from sysfs for PMU
   events, so that we can use that info to pretty print instead of
   printing raw numbers:
 
   # perf stat -e power/energy-ram/,power/energy-gpu/ sleep 2
 
    Performance counter stats for 'system wide':
 
               1.64 Joules power/energy-ram/
               0.20 Joules power/energy-gpu/
 
        2.001228914 seconds time elapsed
   #
   # grep -m1 "model name" /proc/cpuinfo
   model name	: Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz
   #
 
 - The small llvm.cpp file used to check if the llvm devel files are present was
   incorrectly deleted when removing the BPF event in 'perf trace', put it back
   as it is also used by tools/bpf/bpftool, that uses llvm routines to do
   disassembly of BPF object files.
 
 - Fix use of addr_location__exit() in dlfilter__object_code(), making sure that
   it is only used to pair a previous addr_location__init() call.

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.
