Subject: [PATCH 10/14] powerpc/mm: Use generic version of pmdp_clear_flush_young
Date: Mon, 7 Mar 2016 19:09:30 +0530 [thread overview]
Message-ID: <1457357974-20839-10-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1457357974-20839-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
The radix variant is going to require a flush_pmd_tlb_range. With
flush_pmd_tlb_range added, pmdp_clear_flush_young is same as the generic
version. So drop the powerpc specific variant
