Vitaly Chikunov 49e6f6e2bc perf beauty: Fix fsconfig generator 
[ Upstream commit 2e1daee14e67fbf9b27280b974e2c680a22cabea ]

After gnulib update sed stopped matching `[[:space:]]*+' as before,
causing the following compilation error:

  In file included from builtin-trace.c:719:
  trace/beauty/generated/fsconfig_arrays.c:2:3: error: expected expression before ']' token
      2 |  [] = "",
	|   ^
  trace/beauty/generated/fsconfig_arrays.c:2:3: error: array index in initializer not of integer type
  trace/beauty/generated/fsconfig_arrays.c:2:3: note: (near initialization for 'fsconfig_cmds')

Fix this by correcting the regular expression used in the generator.
Also, clean up the script by removing redundant egrep, xargs, and printf
invocations.

Committer testing:

Continues to work:

  $ cat tools/perf/trace/beauty/fsconfig.sh
  #!/bin/sh
  # SPDX-License-Identifier: LGPL-2.1

  if [ $# -ne 1 ] ; then
  	linux_header_dir=tools/include/uapi/linux
  else
  	linux_header_dir=$1
  fi

  linux_mount=${linux_header_dir}/mount.h

  printf "static const char *fsconfig_cmds[] = {\n"
  ms='[[:space:]]*'
  sed -nr "s/^${ms}FSCONFIG_([[:alnum:]_]+)${ms}=${ms}([[:digit:]]+)${ms},.*/\t[\2] = \"\1\",/p" \
  	${linux_mount}
  printf "};\n"
  $ tools/perf/trace/beauty/fsconfig.sh
  static const char *fsconfig_cmds[] = {
  	[0] = "SET_FLAG",
  	[1] = "SET_STRING",
  	[2] = "SET_BINARY",
  	[3] = "SET_PATH",
  	[4] = "SET_PATH_EMPTY",
  	[5] = "SET_FD",
  	[6] = "CMD_CREATE",
  	[7] = "CMD_RECONFIGURE",
  };

Ian Rogers 1835a026e2 perf trace: Fix the selection for architectures to generate the errno name tables 
[ Upstream commit 7597ce89b3ed239f7a3408b930d2a6c7a4c938a1 ]

Make the architecture test directory agree with the code comment.

Committer notes:

This was split from a larger patch.

The code was assuming the developer always worked from tools/perf/, so make sure we
do the test -d having $toolsdir/perf/arch/$arch, to match the intent expressed in the comment,
just above that loop.
