Its filename was mm-enable-mmu_gather_rcu_table_free-for-m68k-coldfire.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: "Lorenzo Stoakes (ARM)" Subject: mm: enable MMU_GATHER_RCU_TABLE_FREE for m68k-coldfire Date: Tue, 08 Sep 2026 13:32:16 +0100 Similar to sun3, the coldfire variant of m68k uses 2-level page tables. Update its __pte_free_tlb() function to use tlb_remove_ptdesc() in order that, with CONFIG_MMU_GATHER_RCU_TABLE_FREE, page tables are freed under RCU. The page tables occupy a page each and have no odd semantics, so this change suffices to allow enabling of CONFIG_MMU_GATHER_RCU_TABLE_FREE for m68k-coldfire, so do so. This forms part of an overall effort to switch every architecture to this mode.
