History
David Hildenbrand c30d6bc8d0 mm/mmu_gather: pass "delay_rmap" instead of encoded page to __tlb_remove_page_size() 
We have two bits available in the encoded page pointer to store additional
information.  Currently, we use one bit to request delay of the rmap
removal until after a TLB flush.

We want to make use of the remaining bit internally for batching of
multiple pages of the same folio, specifying that the next encoded page
pointer in an array is actually "nr_pages".  So pass page + delay_rmap
flag instead of an encoded page, to handle the encoding internally.
