From e77b0852b551ffd8b29fa0225e1ef62c195e3160 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 26 Jul 2016 15:24:12 -0700 Subject: mm/mmu_gather: track page size with mmu gather and force flush if page size change This allows an arch which needs to do special handing with respect to different page size when flushing tlb to implement the same in mmu gather.
