From: "Mike Rapoport (IBM)" <rppt@kernel.org> The prompt and help text of ARCH_FORCE_MAX_ORDER are not even close to describe this configuration option. Update both to actually describe what this option does. Signed-off-by: Mike Rapoport (IBM) <rppt@kernel.org> --- arch/arm/Kconfig | 16 +++++++++------- 1 file changed, 9 insertions(+), 7 deletions(-)
