* Additionally there are a few opt-in features:
*
* HAVE_MMU_GATHER_PAGE_SIZE
* MMU_GATHER_PAGE_SIZE
*
* This ensures we call tlb_flush() every time tlb_change_page_size() actually
* changes the size and provides mmu_gather::page_size to tlb_flush().
*
* This might be useful if your architecture has size specific TLB
* invalidation instructions.
*
* MMU_GATHER_RCU_TABLE_FREE
*
* This provides tlb_remove_table(), to be used instead of tlb_remove_page()
