Subject: [PATCH v9 35/51] selftest/vm: typecast the pkey register
Date: Mon,  6 Nov 2017 00:57:27 -0800	[thread overview]
Message-ID: <1509958663-18737-36-git-send-email-linuxram@us.ibm.com> (raw)
In-Reply-To: <1509958663-18737-1-git-send-email-linuxram@us.ibm.com>

This is in preparation to accomadate a differing size register
across architectures.
