Subject: [PATCH -V1 7/9] arch/powerpc: Use 50 bits of VSID in slbmte
Date: Fri, 29 Jun 2012 19:47:35 +0530 [thread overview]
Message-ID: <1340979457-26018-8-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1340979457-26018-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
From: "Aneesh Kumar K.V" <aneesh.kumar@linux.vnet.ibm.com>
Increase the number of valid VSID bits in slbmte instruction.
We will use the new bits when we increase valid VSID bits.
