Will Deacon 71c8fc0c96 arm64: mm: Ensure writes to swapper are ordered wrt subsequent cache maintenance ... When rewriting swapper using nG mappings, we must performance cache maintenance around each page table access in order to avoid coherency problems with the host's cacheable alias under KVM. To ensure correct ordering of the maintenance with respect to Device memory accesses made with the Stage-1 MMU disabled, DMBs need to be added between the maintenance and the corresponding memory access. This patch adds a missing DMB between writing a new page table entry and performing a clean+invalidate on the same line.
