Subject: [PATCH 08/19] mips: expose number of page table levels on Kconfig level
Date: Fri, 30 Jan 2015 16:43:17 +0200	[thread overview]
Message-ID: <1422629008-13689-9-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1422629008-13689-1-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.
