Subject: Re: [PATCH v3 7/9] mm/kasan: use hw_pte_t for the early shadow PTE table
Date: Tue, 22 Sep 2026 17:21:30 +0000 [thread overview]
Message-ID: <20260922172131.615D91F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260922-pte0-v3-7-5670b8cb9059@arm.com>
> kasan_early_shadow_pte is a complete PTE table rather than a software
> PTE value. Declare and define its elements as hw_pte_t so the object uses
> the PTE table storage type.
>
> Read the first element through ptep_get(), which returns the software PTE
> value expected by note_page_pte(), instead of accessing hw_pte_t storage
> directly. This also uses the accessor selected by the architecture.
>
> No architecture selects ARCH_HAS_HW_PTE_T at this point, so the storage
> representation remains unchanged.
