scripts/updatedefconfigs.sh

#!/bin/bash
#
# This script is meant to update all defconfigs when any Kconfig changes.
# Just go to kernel root directory and execute:
# $ scripts/updatedefconfigs.sh
#
# For each ${ARCH}_XXX_defconfig inside arch/x86/configs it will ask to
# run either make oldconfig, make menuconfig or make xconfig.
# In the end all defconfigs will be updated and ready for a patch.
