Subject: [PATCH V4 17/18] powerpc/mm: Use generic version of pmdp_clear_flush_young
Date: Tue, 23 Feb 2016 10:18:19 +0530 [thread overview]
Message-ID: <1456202900-5454-18-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1456202900-5454-1-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.
