Subject: [PATCH v2 06/14] init: fold build_all_zonelists() and page_alloc_init_cpuhp() to mm_init()
Date: Tue, 21 Mar 2023 19:05:05 +0200 [thread overview]
Message-ID: <20230321170513.2401534-7-rppt@kernel.org> (raw)
In-Reply-To: <20230321170513.2401534-1-rppt@kernel.org>
From: "Mike Rapoport (IBM)" <rppt@kernel.org>
Both build_all_zonelists() and page_alloc_init_cpuhp() must be called
after SMP setup is complete but before the page allocator is set up.
Still, they both are a part of memory management initialization, so move
them to mm_init().
