From: Rob Landley <rob@landley.net> Remove perl from make headers_install by replacing a perl script (doing a simple regex search and replace) with a smaller and faster shell script implementation. The new shell script is a single for loop calling sed and piping its output through unifdef to produce the target file. Changes from previous version: Added help text and a check for the right number of arguments. Removed unused ARCH input from script and makefile (the makefile incorporates ARCH into INDIR, so the script doesn't care), fixed a whitespace mistake in the makefile pointed out by Sam Ravnborg, changed the shebang to #!/bin/sh and tested under bash and dash. put_changelog_here Signed-off-by: Rob Landley <rob@landley.net> --- scripts/Makefile.headersinst | 6 ++-- scripts/headers_install.pl | 46 --------------------------------- scripts/headers_install.sh | 36 +++++++++++++++++++++++++ 3 files changed, 39 insertions(+), 49 deletions(-) diff -ruN linux-2.6.28/scripts/headers_install.sh linux-2.6.28-new/scripts/headers_install.sh --- linux-2.6.28/scripts/headers_install.sh 1969-12-31 18:00:00.000000000 -0600 +++ linux-2.6.28-new/scripts/headers_install.sh 2009-01-02 22:35:17.000000000 -0600 @@ -0,0 +1,36 @@ +#!/bin/sh + +if [ $# -lt 2 ] +then + echo "Usage: headers_install.sh INDIR OUTDIR [FILES...] + echo + echo "Prepares kernel header files for use by user space, by removing" + echo "all compiler.h definitions and #includes, and removing any" + echo "#ifdef __KERNEL__ sections." + echo + echo "INDIR: directory to read each kernel header FILE from." + echo "OUTDIR: directory to write each userspace header FILE to." + echo "FILES: list of header files to operate on." + + exit 1 +fi + +# Grab arguments + +INDIR="$1" +shift +OUTDIR="$1" +shift + +# Iterate through files listed on command line + +for i in "$@" +do + sed -r \ + -e 's/([ \t(])(__user|__force|__iomem)[ \t]/\1/g' \ + -e 's/__attribute_const__([ \t]|$)/\1/g' \ + -e 's@^#include <linux/compiler.h>@@' "$INDIR/$i" | + scripts/unifdef -U__KERNEL__ - > "$OUTDIR/$i" +done + +exit 0 diff -ruN linux-2.6.28/scripts/Makefile.headersinst linux-2.6.28-new/scripts/Makefile.headersinst --- linux-2.6.28/scripts/Makefile.headersinst 2008-12-24 17:26:37.000000000 -0600 +++ linux-2.6.28-new/scripts/Makefile.headersinst 2009-01-02 22:36:42.000000000 -0600 @@ -44,8 +44,8 @@ quiet_cmd_install = INSTALL $(printdir) ($(words $(all-files))\ file$(if $(word 2, $(all-files)),s)) cmd_install = \ - $(PERL) $< $(srctree)/$(obj) $(install) $(SRCARCH) $(header-y); \ - $(PERL) $< $(objtree)/$(obj) $(install) $(SRCARCH) $(objhdr-y); \ + $(CONFIG_SHELL) $< $(srctree)/$(obj) $(install) $(header-y); \ + $(CONFIG_SHELL) $< $(objtree)/$(obj) $(install) $(objhdr-y); \ touch $@ quiet_cmd_remove = REMOVE $(unwanted) @@ -64,7 +64,7 @@ @: targets += $(install-file) -$(install-file): scripts/headers_install.pl $(input-files) FORCE +$(install-file): scripts/headers_install.sh $(input-files) FORCE $(if $(unwanted),$(call cmd,remove),) $(if $(wildcard $(dir $@)),,$(shell mkdir -p $(dir $@))) $(call if_changed,install) diff -ruN linux-2.6.28/scripts/headers_install.pl linux-2.6.28-new/scripts/headers_install.pl --- linux-2.6.28/scripts/headers_install.pl 2008-12-24 17:26:37.000000000 -0600 +++ linux-2.6.28-new/scripts/headers_install.pl 1969-12-31 18:00:00.000000000 -0600 @@ -1,46 +0,0 @@ -#!/usr/bin/perl -w -# -# headers_install prepare the listed header files for use in -# user space and copy the files to their destination. -# -# Usage: headers_install.pl readdir installdir arch [files...] -# readdir: dir to open files -# installdir: dir to install the files -# arch: current architecture -# arch is used to force a reinstallation when the arch -# changes because kbuild then detect a command line change. -# files: list of files to check -# -# Step in preparation for users space: -# 1) Drop all use of compiler.h definitions -# 2) Drop include of compiler.h -# 3) Drop all sections defined out by __KERNEL__ (using unifdef) - -use strict; - -my ($readdir, $installdir, $arch, @files) = @ARGV; - -my $unifdef = "scripts/unifdef -U__KERNEL__"; - -foreach my $file (@files) { - local *INFILE; - local *OUTFILE; - my $tmpfile = "$installdir/$file.tmp"; - open(INFILE, "<$readdir/$file") - or die "$readdir/$file: $!\n"; - open(OUTFILE, ">$tmpfile") or die "$tmpfile: $!\n"; - while (my $line = <INFILE>) { - $line =~ s/([\s(])__user\s/$1/g; - $line =~ s/([\s(])__force\s/$1/g; - $line =~ s/([\s(])__iomem\s/$1/g; - $line =~ s/\s__attribute_const__\s/ /g; - $line =~ s/\s__attribute_const__$//g; - $line =~ s/^#include <linux\/compiler.h>//; - printf OUTFILE "%s", $line; - } - close OUTFILE; - close INFILE; - system $unifdef .
