Stafford Horne 27dff9a9c2 openrisc: fix SMP tlb flush NULL pointer dereference ... Throughout the OpenRISC kernel port VMA is passed as NULL when flushing kernel tlb entries. Somehow this was missed when I was testing c28b27416d ("openrisc: Implement proper SMP tlb flushing") and now the SMP kernel fails to completely boot. In OpenRISC VMA is used only to determine which cores need to have their TLB entries flushed. This patch updates the logic to flush tlbs on all cores when the VMA is passed as NULL. Also, we update places VMA is passed as NULL to use flush_tlb_kernel_range instead. Now, the only place VMA is passed as NULL is in the implementation of flush_tlb_kernel_range.
