Subject: [PATCH 1/8] sparc/mm: remove register_page_bootmem_info()
Date: Mon, 11 May 2026 16:05:29 +0200	[thread overview]
Message-ID: <20260511-bootmem_info_prep-v1-1-3fb0be6fc688@kernel.org> (raw)
In-Reply-To: <20260511-bootmem_info_prep-v1-0-3fb0be6fc688@kernel.org>

sparc does not select CONFIG_HAVE_BOOTMEM_INFO_NODE, therefore,
register_page_bootmem_info_node() is a nop.

Let's just get rid of register_page_bootmem_info().
