Subject: [PATCH v14 02/15] selftests/powerpc: Use the new SPRN_DSCR_PRIV definiton
Date: Mon, 12 Sep 2016 15:33:12 +0800	[thread overview]
Message-ID: <1473665605-11890-3-git-send-email-wei.guo.simon@gmail.com> (raw)
In-Reply-To: <1473665605-11890-1-git-send-email-wei.guo.simon@gmail.com>

From: Anshuman Khandual <khandual@linux.vnet.ibm.com>

Now that the new DSCR register definitions (SPRN_DSCR_PRIV and
SPRN_DSCR) are defined outside this directory, use them instead.
