Subject: Re: [PATCH v2 07/12] mm: enable MMU_GATHER_RCU_TABLE_FREE for m68k-coldfire
Date: Tue, 08 Sep 2026 12:46:03 +0000 [thread overview]
Message-ID: <20260908124607.457821F00A3A@smtp.kernel.org> (raw)
In-Reply-To: <20260908-rcu-pagetable-freeing-v2-7-1f60b64e878e@kernel.org>
> 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.
