/*
 * Generic MMU-gather implementation.
 *
 * The mmu_gather data structure is used by the mm code to implement the
 * correct and efficient ordering of freeing pages and TLB invalidations.
 *
 * This correct ordering is:
 *
 *  1) unhook page
 *  2) TLB invalidate page
 *  3) free page
 *
 * That is, we must never free a page before we have ensured there are no live
 * translations left to it. Otherwise it might be possible to observe (or
 * worse, change) the page content after it has been reused.
 *
 * The mmu_gather API consists of:
 *
 *  - tlb_gather_mmu() / tlb_gather_mmu_fullmm() / tlb_gather_mmu_vma() /
 *    tlb_finish_mmu()
 *
 *    start and finish a mmu_gather
 *
 *    Finish in particular will issue a (final) TLB invalidate and free
 *    all (remaining) queued pages.
 *
 *  - tlb_start_vma() / tlb_end_vma(); marks the start / end of a VMA
 *
 *    Defaults to flushing at tlb_end_vma() to reset the range; helps when
 *    there's large holes between the VMAs.
 *
 *  - tlb_remove_table()
 *
 *    tlb_remove_table() is the basic primitive to free page-table directories
 *    (__p*_free_tlb()).  In it's most primitive form it is an alias for
 *    tlb_remove_page() below, for when page directories are pages and have no
 *    additional constraints.
 *
 *    See also MMU_GATHER_TABLE_FREE and MMU_GATHER_RCU_TABLE_FREE.
 *
 *  - tlb_remove_page() / __tlb_remove_page()
 *  - tlb_remove_page_size() / __tlb_remove_page_size()
 *
 *    __tlb_remove_page_size() is the basic primitive that queues a page for
 *    freeing. __tlb_remove_page() assumes PAGE_SIZE. Both will return a
 *    boolean indicating if the queue is (now) full and a call to
 *    tlb_flush_mmu() is required.
 *
 *    tlb_remove_page() and tlb_remove_page_size() imply the call to
 *    tlb_flush_mmu() when required and has no return value.
 *
 *  - tlb_change_page_size()
 *
 *    call before __tlb_remove_page*() to set the current page-size; implies a
 *    possible tlb_flush_mmu() call.
