* 'arm/defconfig/reduced-v2.6.35-rc1' of git://git.pengutronix.de/git/ukl/linux-2.6:
ARM: reduce defconfigs
This is a big change, but results in no loss of information, despite us
losing almost 200k lines:
177 files changed, 652 insertions(+), 194157 deletions(-)
and Grant Likely thinks powerpc can also use the same reduction
technique.
The python script that did the reduction looks like this:
#! /usr/bin/env python
# vim: set fileencoding=utf-8 :

import re
import subprocess
import os
import sys
# This prevents including a timestamp in the .config which makes comparing a
# bit easier.
os.environ['KCONFIG_NOTIMESTAMP'] = 'Yes, please'
# XXX: get these using getopt
kernel_tree = '' # os.path.join(os.environ['HOME'], 'gsrc', 'linux-2.6')
arch = 'arm'
target = sys.argv[1]
defconfig_src = os.path.join(kernel_tree, 'arch/%s/configs/%s' % (arch, target))
subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])
origconfig = list(open('.config'))
config = list(origconfig)
config_size = os.stat('.config').st_size
i = 0
while i < len(config):
print 'test for %r' % config[i]
defconfig = open(defconfig_src, 'w')
defconfig.writelines(config[:i])
defconfig.writelines(config[i + 1:])
defconfig.close()
subprocess.check_call(['make', '-s', 'ARCH=%s' % arch, target])
if os.stat('.config').st_size == config_size and list(open('.config')) == origconfig:
del config[i]
else:
i += 1
defconfig = open(defconfig_src, 'w')
defconfig.writelines(config)
defconfig.close()
which is pretty self-explanatory.
