Subject: [PATCHv2 11/19] powerpc: expose number of page table levels on Kconfig level
Date: Sat, 31 Jan 2015 02:27:27 +0200 [thread overview]
Message-ID: <1422664047-220637-1-git-send-email-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <1422629008-13689-12-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.
