Subject: [RFC v3 PATCH 15/25] ARM: kexec: disallow kexec for NOMMU builds
Date: Fri,  2 Dec 2016 15:05:33 +0000	[thread overview]
Message-ID: <1480691143-19845-16-git-send-email-vladimir.murzin@arm.com> (raw)
In-Reply-To: <1480691143-19845-1-git-send-email-vladimir.murzin@arm.com>

While building for NOMMU the following error shows up:

kernel/built-in.o: In function `kimage_free_entry':
memremap.c:(.text+0x4dafc): undefined reference to `arch_phys_to_idmap_offset'
memremap.c:(.text+0x4db04): undefined reference to `arch_phys_to_idmap_offset'
kernel/built-in.o: In function `kimage_alloc_page':
memremap.c:(.text+0x4dbc0): undefined reference to `arch_phys_to_idmap_offset'
memremap.c:(.text+0x4dbc8): undefined reference to `arch_phys_to_idmap_offset'
memremap.c:(.text+0x4dc1c): undefined reference to `arch_phys_to_idmap_offset'

That comes from Kexec, add dependency on MMU there.
