Subject: [PATCH v2] m68k: fix flatmem memory model setup
Date: Sun, 28 Feb 2021 20:08:28 +0100	[thread overview]
Message-ID: <20210228190828.392974-1-angelo@kernel-space.org> (raw)

Detected a broken boot on mcf54415, likely introduced from

commit 4bfc848e0981
("m68k/mm: enable use of generic memory_model.h for !DISCONTIGMEM")

Fix ARCH_PFN_OFFSET to be a pfn.

Signed-off-by: Angelo Dureghello <angelo@kernel-space.org>

Change for v2:
- replace PAGE_OFFSET with m68k_memory[0].addr
