Subject: [RFC PATCH 8/9] powerpc/powernv: Remove machine check handling in OPAL.
Date: Wed, 07 Aug 2013 15:09:22 +0530	[thread overview]
Message-ID: <20130807093922.5389.10511.stgit@mars.in.ibm.com> (raw)
In-Reply-To: <20130807093609.5389.26534.stgit@mars.in.ibm.com>

From: Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>

Now that we are ready to handle machine check directly in linux, do not
register with firmware to handle machine check exception.
