[-- Attachment #1: 0006-kconfig-enable-CONFIG_IKCONFIG-from-streamline_confi.patch --]

From: Steven Rostedt <srostedt@redhat.com>

Ingo Molnar suggested that the streamline_config.pl should enable
CONFIG_IKCONFIG to keep the current config in the kernel.
Then we can use scripts/extract-ikconfig to find the current
modules.

This patch changes streamline_config.pl to check if CONFIG_IKCONFIG
is not set, and if it is not, it enables it to be a module.

[ Impact: make current config options easier to find ]
