Subject: [PATCH 8/8] Add documentation for extra boot parameters
Date: Fri,  5 May 2006 18:37:27 +0100 (IST)	[thread overview]
Message-ID: <20060505173727.9030.40142.sendpatchset@skynet> (raw)
In-Reply-To: <20060505173446.9030.42837.sendpatchset@skynet>

Once all patches are applied, two new command-line parameters exist -
kernelcore and noeasyrclm. This patch adds the necessary documentation.
