Subject: [PATCHv4 05/12] mips: Use generic_pmdp_establish as pmdp_establish
Date: Wed, 13 Dec 2017 13:57:49 +0300	[thread overview]
Message-ID: <20171213105756.69879-6-kirill.shutemov@linux.intel.com> (raw)
In-Reply-To: <20171213105756.69879-1-kirill.shutemov@linux.intel.com>

MIPS doesn't support hardware dirty/accessed bits.
generic_pmdp_establish() is suitable in this case.
