Subject: [PATCH 02/12] MIPS: Netlogic: Fix low-level flush on core wakeup
Date: Fri, 13 Jul 2012 21:53:15 +0530	[thread overview]
Message-ID: <1342196605-4260-3-git-send-email-jayachandranc@netlogicmicro.com> (raw)
In-Reply-To: <1342196605-4260-1-git-send-email-jayachandranc@netlogicmicro.com>

The L1D cache flush needs to be done for more iterations to ensure
that the cache is clean before waking up threads.

This change is experimental, but should not have any negative impact.
