Also count CONFIG_MODVERSIONS warnings, and print a NOTE at start of
SECTION 2 if any were issued.  Section 2 will be empty if the build is
lacking this CONFIG_ item, and user may have missed the warnings, as
they're off screen.

Sort SECTION 2 modules by name.  Within those module listings, sort
the symbol providers by name, and remove the count, as it is
misleading; its the kernel-wide count of uses of that symbol, not the
count pertaining to the module being outlined.  (this can be seen by
grepping the output for a single symbol).  The count is still used to
sort the symbols.

Avoid spawning a shell pipeline doing cat, grep, sed, and do it all
inside perl.  The <*.c> globbing construct works at least as far back
as 5.8.9

Note that this is not just an optimization; the sed command
in the pipeline was unterminated, due to lack of escape on the
end-of-line (\$) in the regex, resulting in this:

    $ perl ../linux-2.6/scripts/export_report.pl  > /dev/null
    sed: -e expression #1, char 5: unterminated `s' command
    sh: .mod.c/: not found

Comments on an earlier patch sought an all-perl implementation.

Use local file handles, use three argument open.
Don't modify arguments in perl grep (use sed instead)

This patch fixes an annoying bug of export_report.pl missing the usages
of some exports.

Signed-off-by: Adrian Bunk <bunk@kernel.org>
Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

The following patch provides the ability to generate a report of
	(1) All the exported symbols and their in-kernel-module usage count
	(2) For each module, lists the modules and their exported symbols, on
	                  which it depends.

	the report can be generated by executing:
	perl scripts/export_report

The tool warns if the modules are not build using MODVERSIONING.
