Subject: [PATCH 2/2] metag: don't check for cache aliasing on smp cpu boot
Date: Mon, 24 Jun 2013 13:49:48 +0100 [thread overview]
Message-ID: <1372078188-26602-3-git-send-email-james.hogan@imgtec.com> (raw)
In-Reply-To: <1372078188-26602-1-git-send-email-james.hogan@imgtec.com>
The cache configuration of the boot cpu is now duplicated to secondary
cpus, so there's no need to check for cache aliasing again when a
secondary cpu is booted. Therefore remove the check from
secondary_start_kernel().
