Subject: [PATCH 10/27] mm/bootmem_info: export register_page_bootmem_memmap
Date: Mon, 27 Jan 2025 23:21:50 +0000 [thread overview]
Message-ID: <20250127232207.3888640-11-fvdl@google.com> (raw)
In-Reply-To: <20250127232207.3888640-1-fvdl@google.com>
If other mm code wants to use this function for early
memmap inialization (on the platforms that have it),
it should be made available properly, not just
unconditionally in mm.h
Make this function available for such cases.
