Subject: [PATCH 8/8] powerpc/mm: Use generic version of pmdp_clear_flush_young
Date: Tue,  1 Mar 2016 12:59:24 +0530	[thread overview]
Message-ID: <1456817364-3329-9-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1456817364-3329-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>

The radix variant is going to require a flush_tlb_range. We can't then
have this as static inline because of the usage of HPAGE_PMD_SIZE. So
we are forced to make it a function in which case we can use the generic version.
