[PATCH 1/6] asm-generic/tlb: Track freeing of page-table directories in struct mmu_gather

From: Peter Zijlstra Some architectures require different TLB invalidation instructions depending on whether it is only the last-level of page table being changed, or whether there are also changes to the intermediate (directory) entries higher up the tree. Add a new bit to the flags bitfield in
