Subject: [PATCH AUTOSEL 4.4 082/100] ARM: 8951/1: Fix Kexec compilation issue.
Date: Fri, 14 Feb 2020 11:24:06 -0500 [thread overview]
Message-ID: <20200214162425.21071-82-sashal@kernel.org> (raw)
In-Reply-To: <20200214162425.21071-1-sashal@kernel.org>
From: Vincenzo Frascino <vincenzo.frascino@arm•com>
[ Upstream commit 76950f7162cad51d2200ebd22c620c14af38f718 ]
To perform the reserve_crashkernel() operation kexec uses SECTION_SIZE to
find a memblock in a range.
SECTION_SIZE is not defined for nommu systems. Trying to compile kexec in
these conditions results in a build error:
linux/arch/arm/kernel/setup.c: In function ‘reserve_crashkernel’:
linux/arch/arm/kernel/setup.c:1016:25: error: ‘SECTION_SIZE’ undeclared
(first use in this function); did you mean ‘SECTIONS_WIDTH’?
crash_size, SECTION_SIZE);
^~~~~~~~~~~~
SECTIONS_WIDTH
linux/arch/arm/kernel/setup.c:1016:25: note: each undeclared identifier
is reported only once for each function it appears in
linux/scripts/Makefile.build:265: recipe for target 'arch/arm/kernel/setup.o'
failed
Make KEXEC depend on MMU to fix the compilation issue.
