Subject: [PATCH V2 09/23] kvm tools: Move arch-specific cmdline init into kvm__arch_set_cmdline()
Date: Fri, 09 Dec 2011 17:54:15 +1100	[thread overview]
Message-ID: <4EE1B097.2090105@ozlabs.org> (raw)
In-Reply-To: <cover.1323413420.git.matt@ozlabs.org>

Different systems will want different base kernel commandlines, e.g. non-x86
systems probably don't need noapic, i8042.* etc., so set the commandline up in
arch-specific code.  Then, if the resulting commandline is empty, don't strcat a
space onto the front.
