Subject: mm/mmu_gather: remove @delay_remap of __tlb_remove_page_size()
Date: Wed, 31 Dec 2025 03:00:26 +0000

__tlb_remove_page_size() is only used in tlb_remove_page_size() with
@delay_remap set to false and it is passed directly to
__tlb_remove_folio_pages_size().

Remove @delay_remap of __tlb_remove_page_size() and call
__tlb_remove_folio_pages_size() with false @delay_remap.
