Namhyung Kim 38672c5033 perf test: Skip perf trace tests when running as non-root
perf trace requires root because it needs to use tracepoints and BPF.
Skip those test when it's not run as root.

Before:
  $ perf test trace
   15: Parse sched tracepoints fields                                  : Skip (permissions)
   80: perf ftrace tests                                               : Skip
  105: perf trace enum augmentation tests                              : FAILED!
  106: perf trace BTF general tests                                    : FAILED!
  107: perf trace exit race                                            : FAILED!
  118: probe libc's inet_pton & backtrace it with ping                 : Skip
  125: Check Arm CoreSight trace data recording and synthesized samples: Skip
  127: Check Arm SPE trace data recording and synthesized samples      : Skip
  132: Check open filename arg using perf trace + vfs_getname          : FAILED!

After:
  $ perf test trace
   15: Parse sched tracepoints fields                                  : Skip (permissions)
   80: perf ftrace tests                                               : Skip
  105: perf trace enum augmentation tests                              : Skip
  106: perf trace BTF general tests                                    : Skip
  107: perf trace exit race                                            : Skip
  118: probe libc's inet_pton & backtrace it with ping                 : Skip
  125: Check Arm CoreSight trace data recording and synthesized samples: Skip
  127: Check Arm SPE trace data recording and synthesized samples      : Skip
  132: Check open filename arg using perf trace + vfs_getname          : Skip

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 reStructuredText 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.
