Subject: [PATCH 2/3] powerpc: Book E: Remove unused CPU_FTR_L2CSR bit
Date: Tue, 20 Mar 2018 08:46:12 +1100 [thread overview]
Message-ID: <1521495973-3237-3-git-send-email-paulus@ozlabs.org> (raw)
In-Reply-To: <1521495973-3237-1-git-send-email-paulus@ozlabs.org>
The CPU_FTR_L2CSR bit is never tested anywhere, so let's reclaim the bit.
