Subject: [PATCHv3 10/17] s390: expose number of page table levels
Date: Thu, 26 Feb 2015 13:35:13 +0200 [thread overview]
Message-ID: <1424950520-90188-11-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1424950520-90188-1-git-send-email-kirill.shutemov@linux.intel.com>
We would want to use number of page table level to define mm_struct.
Let's expose it as CONFIG_PGTABLE_LEVELS.
