Subject: [PATCH 09/15] kconfig: keep config.gz around even if CONFIG_IKCONFIG_PROC is not set
Date: Fri, 11 Sep 2009 15:58:58 -0400 [thread overview]
Message-ID: <20090911200034.904723927@goodmis.org> (raw)
In-Reply-To: 20090911195849.451244684@goodmis.org
[-- Attachment #1: 0009-kconfig-keep-config.gz-around-even-if-CONFIG_IKCONFI.patch --]
[-- Type: text/plain, Size: 1120 bytes --]
From: Steven Rostedt <srostedt@redhat.com>
If CONFIG_IKCONFIG is set but CONFIG_IKCONFIG_PROC is not, then
gcc will optimize the config.gz out, because nobody uses it.
This patch adds "__used" to the config.gz data to keep it around so that
code like extract-ikconfig can still find it.
[ Impact: allow extract-ikconfig to find config.gz ]
