From e3ecf7c7d0829a00a4fb02531338ab9e7e75ea0d Mon Sep 17 00:00:00 2001 From: Qi Zheng Date: Tue, 25 Feb 2025 11:45:53 +0800 Subject: mm: pgtable: convert some architectures to use tlb_remove_ptdesc() Now, the nine architectures of csky, hexagon, loongarch, m68k, mips, nios2, openrisc, sh and um do not select CONFIG_MMU_GATHER_RCU_TABLE_FREE, and just call pagetable_dtor() + tlb_remove_page_ptdesc() (the wrapper of tlb_remove_page()). This is the same as the implementation of tlb_remove_{ptdesc|table}() under !CONFIG_MMU_GATHER_TABLE_FREE, so convert these architectures to use tlb_remove_ptdesc(). The ultimate goal is to make the architecture only use tlb_remove_ptdesc() or tlb_remove_table() for page table pages.
