3.10-stable review patch. If anyone has any objections, please let me know. ------------------ From: Marc Zyngier <marc.zyngier@xxxxxxx> commit 479c5ae2f8a55509b691494cd13691d3dc31d102 upstream. When performing a Stage-2 TLB invalidation, it is necessary to make sure the write to the page tables is observable by all CPUs. For this purpose, add a dsb instruction to __kvm_tlb_flush_vmid_ipa before doing the TLB invalidation itself.
