Subject: [PATCH 2/2] powerpc/e500mc: Doorbells need to be taken w/exceptions disabled
Date: Thu,  8 Jan 2009 18:15:16 -0600	[thread overview]
Message-ID: <1231460116-26383-2-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1231460116-26383-1-git-send-email-galak@kernel.crashing.org>

We use Doorbell interrupts for IPIs and thus we need to make sure we aren't
interrupted in the process of processing the IPI.
