Subject: [PATCH 04/11] kernel: Build bin2c based on config option CONFIG_BUILD_BIN2C
Date: Mon, 27 Jan 2014 13:57:44 -0500 [thread overview]
Message-ID: <1390849071-21989-5-git-send-email-vgoyal@redhat.com> (raw)
In-Reply-To: <1390849071-21989-1-git-send-email-vgoyal@redhat.com>
currently bin2c builds only if CONFIG_IKCONFIG=y. But bin2c will now be
used by kexec too. So make it compilation dependent on CONFIG_BUILD_BIN2C
and this config option can be selected by CONFIG_KEXEC and CONFIG_IKCONFIG.

kexec is a system call that implements the ability to shutdown your
current kernel, and to start another kernel. It is like a reboot
