Subject: arc: use generic_pmdp_establish as pmdp_establish
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=5c8aa7ea4f988f6759b49265b4ad1cdd058e8406;p=openwrt%2Fstaging%2Fblogic.git

arc: use generic_pmdp_establish as pmdp_establish

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