Subject: [PATCH review for 4.9 30/50] qed: Reserve doorbell BAR space for present CPUs
Date: Mon, 25 Sep 2017 01:12:52 +0000 [thread overview]
Message-ID: <20170925011225.10029-30-alexander.levin@verizon.com> (raw)
In-Reply-To: <20170925011225.10029-1-alexander.levin@verizon.com>
From: Ram Amrani <Ram.Amrani@cavium.com>
[ Upstream commit c2dedf8773e873474535bd4a158609b9eda5403d ]
Reserving doorbell BAR space according to the currently active CPUs
may result in a bug if disabled CPUs are later enabled but no
doorbell space was reserved for them.
